LiFePO4 vs lithium ion battery

Which is better LiFePO4 vs lithium ion battery?

/in /by

When it comes to choosing the correct battery for your needs, there are a lot of considerations to make. LiFePO4 and lithium-ion batteries are popular choices, but which is the better option? This article will compare these two battery types in terms of their performance, environmental impact, and cost to help you make an informed decision when choosing between LiFePO4 vs lithium-ion batteries.

LiFePO4 vs lithium ion battery

Background on lithium-ion batteries

History and development of lithium-ion batteries

The history and development of lithium-ion batteries began in the 1970s with actual work by scientists on the technology. In 1985, Akira Yoshino developed a prototype of the modern Li-ion battery, which used a carbonaceous anode instead of lithium metal. This was commercialized by a Sony and Asahi Kasei team led by Yoshio. 

In the late 1970s, a team of global scientists started developing the lithium-ion battery, which was later used in consumer products such as mobile phones and laptops in 1996. Goodenough, Akshaya Padhi, and coworkers proposed lithium iron in the 1990s. 

In 1991, Sony commercialized secondary Lithium-ion batteries for rapid growth in sales and benefits compared to rechargeable battery systems. Alessandro Volta invented the first actual battery in 1800, made of copper (Cu) and zinc discs stacked together. Since then, there has been remarkable progress made with lithium-ion batteries.

How lithium-ion batteries work

Lithium-ion batteries transfer lithium ions and electrons from the anode to the cathode. The movement of the lithium ions creates free electrons in the anode, which creates a charge at the positive current collector. This electrical current flows from the current collector through a powered device (cell phone, computer, etc.) to the negative current collector. 

At the anode, neutral lithium is oxidized and gives up its single electron as it travels toward the cathode. Meanwhile, at the cathode, oxygen molecules accept these electrons and combine them with lithium ions to form molecules of lithium peroxide. This process is reversed when the battery recharges: oxygen molecules break apart and release electrons and lithium ions, which travel back to the anode. This cycle of charging and discharging allows lithium-ion batteries to provide a steady power source.

Advantages of lithium-ion batteries

Lithium-ion batteries offer a variety of advantages over other types of rechargeable batteries. One of the main benefits of these batteries is their high energy density, which is one of the highest in the rechargeable-battery market at 100-265 Wh/kg. This allows for a longer charge time and higher power-to-weight ratio than other types of batteries. 

Additionally, these batteries have a long shelf life, estimated at 5-7 years at 68°F/20°C. They also have high energy efficiency and low self-discharge rate. Furthermore, lithium batteries have a higher depth of discharge than other battery types. All these characteristics make lithium-ion batteries an attractive choice for many applications.

Background on LiFePO4 batteries

History and development of LiFePO4 batteries

The history and development of LiFePO4 batteries date back to the 1970s when fundamental works on lithium-ion batteries began. Since then, remarkable progress has been made in developing LiFePO4 batteries. 

Whittingham proposed using lithium in batteries in 1976 while he was an engineer at an American oil company. In 1996, John B. Goodenough’s research group at the University of Texas published their research on LiFePO4 as a cathode material. 

Subsequently, the technology has been further developed and improved, leading to fast charging, more considerable autonomy, lighter batteries, and lower cost. Moreover, polymer electrolytes have allowed for greater design freedom and higher energy density. Today, LiFePO4 batteries are used in various applications due to their low cost and long lifetime.

How LiFePO4 batteries work

Lithium iron phosphate (LiFePO4) batteries are lithium-ion (Li-Ion) rechargeable batteries. LiFePO4 batteries use lithium iron phosphate as the cathode material, along with a graphite carbon electrode and a metallic current collector. When charging the battery, a charger passes current to the battery, and lithium ions move in or out of the LiFePO4 material. This process releases electricity when discharging the battery. 

The benefits of LiFePO4 batteries over other lithium-ion batteries include their ability to operate in a wide temperature range, making them suitable for various applications.

Advantages of LiFePO4 batteries

LiFePO4 batteries boast many advantages over other lithium batteries and lead acid batteries. They have a longer lifespan, with a 350-day storage capacity, and can last up to four times longer than lead acid batteries. 

In addition, LiFePO4 batteries offer a high discharge capacity of nearly 100% versus 80% for lead-acid batteries, meaning fewer charge cycles are needed. Recent independent degradation tests have also proven that LiFePO4 chemistry is safer and has a longer lifespan than other lithium batteries. All these benefits make LiFePO4 batteries an ideal choice for portable and stationary applications.

Comparison of lithium-ion and LiFePO4 batteries

Comparing lithium-ion (Li-ion) and LiFePO4 batteries is essential to determine the best option for various applications. Li-ion batteries are more energy dense than LiFePO4 batteries, with an energy density ranging from 160-265 Wh/kg, whereas LiFePO4 batteries have an energy density of around 100-170 Wh/kg. 

LiFePO4 batteries have a longer lifespan than Li-ion batteries, with a life expectancy of 5-7 years compared to the 3-5 years of Li-ion batteries. Also, LiFePO4 batteries are generally considered safer than Li-ion batteries due to their lower operating voltages and better safety profile. Cost is also a factor to consider when comparing the two types of battery, as lithium-ion batteries tend to be more expensive than LiFePO4 batteries. 

Finally, the life cycle climate and cost impacts of both batteries should also be considered when comparing. Lithium-ion batteries tend to have a more significant environmental impact than LiFePO4 batteries.

Applications of lithium-ion and LiFePO4 batteries

Lithium-ion batteries are widely used in various electronic devices, from smartphones and laptops to energy storage systems. These rechargeable batteries offer a high energy density, long cycle life, and low self-discharge rate, making them ideal for powering portable devices. Lithium-ion batteries also have the potential for large-scale applications such as grid-level energy storage systems. 

LiFePO4 batteries are also becoming increasingly popular due to their lower cost and cobalt-free construction. They are often used in boats, solar systems, and vehicles such as plug-in hybrids and all-electric cars. LiFePO4 batteries also have advantages over lithium-ion batteries, such as higher thermal stability and longer life cycle. Both batteries should not be disposed of in domestic garbage or recycling bins and require special recycling facilities for proper disposal.

Conclusion

After reviewing the key points of comparison between lithium-ion and LiFePO4 batteries, it is clear that the two technologies have distinct advantages and disadvantages. Lithium-ion cells are more energy-dense, have a higher power output, and are more cost-effective than LiFePO4 batteries. However, LiFePO4 cells have a longer lifespan and are safer than lithium-ion batteries. Depending on the application, either technology may be more suitable. For example, you need a high power output and don’t mind replacing the battery every few years. Lithium-ion batteries could be the better choice. However, if safety is paramount or you require a longer battery life, LiFePO4 cells may be the better option.

8 Packaging Processes For Lithium Polymer Batteries

/560 Comments/in /by

Lithium battery soft packs have good safety performance, so they are widely used in electronic digital products, medical equipment, medical equipment, and handheld electronic equipment. I believe that many people do not understand the packaging process of lithium battery soft packs. Technology will share with you the packaging process of lithium battery soft pack through this article.
1. Soft pack battery.
The soft-wrapped cells that everyone has encountered are all cells that use aluminum-plastic film as the packaging material. Different packaging materials determine the use of different packaging methods. Welding is used for packaging batteries.
2. The outer layer of outer packaging, aluminum plastic film.
The aluminum-plastic composite film can be roughly divided into three layers – the inner layer is the bonding layer, and polyethylene or polypropylene materials are mostly used to play the role of sealing and bonding; the middle layer is aluminum foil, which can avoid the infiltration of water vapor from the outside of the battery. At the same time, the leakage of the internal electrolyte is avoided; the outer layer is a protective layer, and high-melting polyester or nylon materials are mostly used, which have strong mechanical properties, avoid damage to the battery by external forces, and protect the battery.
3. Aluminum-plastic film stamping forming process.
The soft-packed cells can be designed into different sizes according to the needs of customers. After the external dimensions are designed, the corresponding molds need to be opened to stamp and form the aluminum-plastic film. The forming process is also called punching, which is to use a forming die to punch out a core-rolling hole on the aluminum-plastic film.
4. Packaging side sealing, top sealing process.
The packaging process includes two processes of top sealing and side sealing. The first step is to put the wound core into the punched pit, and then fold the unpunched side along the punched pit side.
5. Liquid injection and pre-sealing process.
After the soft-packed cells are sealed on the top side, x-ray must be done to check the parallelism of the core, and then enter the drying room to remove moisture. After standing in the drying room for a few times, it enters the liquid injection and pre-sealing process.
6. Standing, forming, fixture shaping.
After the liquid injection and sealing are completed, the cells need to be left to stand. According to the difference in the production process, it is divided into high temperature static and normal temperature static. The effect of standing is to allow the injected electrolyte to fully infiltrate the machine. , which can then be used to make
7. Two sealing process.
During the second seal, the first step is to puncture the air bag with a guillotine knife, and at the same time, vacuumize, so that the gas and a part of the electrolyte in the air bag will be drawn out. Then immediately carry out the second seal to ensure the airtightness of the cell. Finally, the air bag is cut off, and a soft-packed cell is almost formed.
8. Post-processing.
After the two air bags are cut, it is necessary to trim and fold the edges to ensure that the width of the cells does not exceed the standard. The folded cells will enter the capacity distribution cabinet for capacity separation, which is actually a capacity test.

Lithium Batteries May One Day Replace Conventional Submarine Diesel Engines

Lithium Batteries May One Day Replace Conventional Submarine Diesel Engines

/1 Comment/in /by

With the advancement of lithium technology, it is possible that lithium batteries may one day replace conventional submarines’ diesel engines. The Japanese Navy has already implemented the use of LIBs in its Soryu-class attack subs. South Korea is also testing the technology for their next-generation attack subs. Other applications for LIBs include the US Special Forces delivery vehicle, as well as the Russian Surrogat unmanned mini-sub.

However, the technology has its drawbacks. Lithium is flammable and can catch fire when exposed to water. Leaks in lithium can reach temperatures of 3,600 degrees Fahrenheit. Furthermore, a fire in a lithium battery releases hydrogen gas, which is highly flammable. While the benefits of using lithium batteries for submarines are numerous, there are still significant concerns about the safety of this technology.

While there are a number of downsides to lithium-ion batteries, the technology has proven to be reliable. Japan, for example, plans to build one more Soryu-class submarine with LIBs. The development of a LIB-submarine would also allow Japan to upgrade its older Stirling AIP powered Soryus. So, while LIBs present certain risks, they are expected to make an impact in the future of submarine propulsion.

While LIBs have some risks, these batteries have been proven to be safer than lead-acid batteries. The research and development of light-metal batteries will benefit from this data. The US Navy has already chosen lithium-ion main batteries for its KSS-III batch 2 submarines. In addition, South Korea has chosen to use lithium-ion batteries in its nuclear-powered Soryu-class boats. The seventh Soryu-class boat is also expected to incorporate a combination of Stirling Engines and lithium-ion batteries. These vessels will serve as a bridge between lead-acid and lithium-ion technologies.

The development of LIB batteries is a challenge for the lead-acid-powered submarines. They can’t be fully replaced by lead-acid batteries and will remain a major asset for the military for years to come. But the advancements in the technology have opened up new doors for submarines. The resulting improved performance means they can cruise for longer periods of time under the water.

Despite the risks of Lithium-ion batteries, they are the most reliable option for submarines. Although the lithium-ion batteries are safer than lead-acid batteries, they do have some drawbacks. In addition to high cost, they have high maintenance and are not completely safe to use in the ocean. Moreover, they are expensive to operate, requiring extensive maintenance.

The benefits of LIBs are considerable. In addition to their high-speed capability, they are also incredibly safe and durable. If the marine environment is a threat to the life of a submarine, it is essential to ensure that it is safe to use and a reliable and long-lasting power supply. Ultimately, LIBs will save lives. But for now, these batteries are not without risks.

Because of the huge benefits of lithium-ion batteries for underwater vehicles, they have many other advantages. Compared to conventional submarines, they have a lower cost than lead-acid submarines. They can also be operated for longer periods of time. This makes lithium-ion-powered subs an attractive option for many companies and governments. This technology can be used in other fields as well, including for commercial purposes.

The use of lithium batteries for conventional submarines could dramatically reduce their costs. The cost of lithium-ion batteries could be cheaper than traditional lead-acid batteries, and the technology may be more efficient than lead-acid. Additionally, the high-energy density of lithium-ion-based batteries will provide longer service life. They are also more reliable than lead-acid batteries.

The development of lithium-ion batteries for submarines is an exciting development. The advanced batteries will give the submarines better endurance under water, which is crucial for a modern submarine. These batteries may also be the main power supply for conventional submarines. They are not only cheaper than lead-acid batteries, but they are lighter, more efficient and more environmentally friendly. In the future, these submarines may use this technology to be able to operate at greater depths than ever before.

How to Detect the Charging Loss of an 18650 Lithium Battery Pack

How to Detect the Charging Loss of an 18650 Lithium Battery Pack

/200 Comments/in /by

How to detect the charging loss of an 18650 lithium battery pack?
1. Battery consumption performance: battery voltage does not go up and capacity decreases. Measure directly with a voltmeter, if the voltage across the 18650 battery is lower than 2.7V or there is no voltage. Indicates that the battery or battery pack is damaged. The normal voltage is 3.0V ~ 4.2V (generally the 3.0V battery will cut off the voltage, the 4.2V battery voltage will be fully charged, and some have 4.35V).
2. If the battery voltage is lower than 2.7V, you can use the charger (4.2V) to charge the battery. After ten minutes, if the battery voltage has rebounded, you can continue to charge until the charger indicates that it is fully charged, and then check the full voltage.
If the fully charged voltage is 4.2V, it means that the battery is normal. It should be that the power consumption was too much in the last use, and the battery is cut off. If the fully charged voltage is much lower than 4.2V, it means the battery is damaged. If the battery has been used for a long time, it can be judged that the battery life has expired and the capacity is basically exhausted. should be replaced. Basically there is no way to fix it. After all, lithium batteries have a lifespan, not infinite.
3. If the 18650 lithium battery pack is measured and the battery has no voltage, there are two situations at this time. One is that the battery was originally good, and it was caused by long-term power loss storage. This kind of battery has a certain probability of recovery. Generally, it is activated by a lithium battery pulse. It is possible to recharge the battery several times in a short period of time by using an instrument (lithium battery charging and discharging instrument). Generally, the repair cost is not low, and it is better to buy a new one. Another possibility is that the battery is completely worn out, the battery separator is broken down, and the positive and negative electrodes are short-circuited. There is no way to fix this kind of thing, just buy a new one.
18650 lithium battery pack battery repair method principle:
1. The metal surface of the 18650 lithium battery pack that has been used for a long time will be oxidized to a certain extent, which will lead to poor contact between the mobile phone battery and the mobile phone, and the use time of the lithium battery will be shortened. Rusty substances that make the battery better in contact with the phone.
2. The low temperature can change the electrolyte inside the lithium battery pack and promote the chemical reaction of the battery that has just been frozen. The use of lithium batteries is actually a charging and discharging process. During this time, the negative and positive charges in the battery collide with each other. When the lithium battery is placed in a low temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface will change significantly, resulting in a temporary inactivity inside the battery and a reduction in leakage current. So after charging again, the standby time of the phone will increase.
The cycle life of the lithium battery pack is about 600 times. If there are too many charging times, the thermal motion of the molecules will gradually destroy the microstructure of the internal molecular arrangement, and the efficiency of storing electric charges will gradually decrease.

How to DIY a 12v LiFePO4 Battery Pack From a 32650 LiFePO4 Battery Cell

How to DIY a 12v LiFePO4 Battery Pack From a 32650 LiFePO4 Battery Cell

/106 Comments/in /by

Nowadays, many rechargeable electrical appliances in life use lithium batteries, such as soft packs, cylindrical, rectangular and so on. Among them, cylindrical lithium batteries are divided into various models according to their size, such as the most common 18650, 22650, 32650 and so on. The number 18 in the model like 18650 indicates the diameter of the battery, 65 indicates the length of the battery, and 0 indicates that the battery is a cylinder.

The voltage of a single-cell lithium battery is generally 3.2V to 3.7v, and the voltage used by many electronic devices is 12V, so we need to use multiple lithium batteries to form a group to achieve 12v, and the lithium battery assembly also needs to be equipped with a protective plate.

The main purpose of the protection board is to play overload protection, short circuit protection, overheat protection, low voltage protection, overvoltage protection, battery balance, overcharge protection, etc., mainly to protect the battery from being damaged.

Since the capacity of a single battery is relatively small, 12 32650 lithium batteries are prepared, four are connected in series to form a group of 12V, and then three groups of 12V are connected in parallel to increase the capacity and voltage.

Assembling the battery requires the use of nickel tape, high temperature tape, and battery brackets.

Generally, the connection of lithium batteries is to use spot welding to bring the nickel to the point. If there is no spot welding machine, you can use sandpaper to polish both ends of the battery, and then you can use an electric soldering iron to weld.

Get the battery line, measure the voltage, and see if the capacity is the same. Don’t put the different ones together.

Then install the battery and battery holder and arrange them in a positive and negative order.

Then wrap the heat resistant tape around it.

Connect the batteries with nickel tape, a soldering iron will do without a spot welder. By the way, stick the protective plate on top of the tape.

For the effect of spot welding of nickel strips, it is necessary to distinguish which one is connected with which one, otherwise it will cause a short circuit.

Then solder the protection board and the plug. Generally, the protection board will indicate the connection method in detail, and it is enough to connect with wires.

If you feel that one plug is too few, you can add another one, and the 12V lithium battery is completed.

Use and Maintenance of Electric Vehicle Lithium Batteries

Use and Maintenance of Electric Vehicle Lithium Batteries

/in /by

In recent years, lithium battery electric vehicles have been the development direction of various countries. It can be seen from the market and the investment of various car companies that they have made efforts in electric vehicles. Now, there is a trend of lithium battery electric vehicles replacing internal combustion engine vehicles in some parts of our country, because lithium batteries have strong sailing ability, ranging from more than 100 kilometers to 500 kilometers of Tesla, and you get what you get for every penny, so in the price It is also more expensive than an internal combustion engine car. So, for lithium battery electric vehicles, how should we use and maintain them?

1. It should be checked regularly during use. You can contact the sales center or the maintenance department of the agent for inspection, repair or matching. If there is a need to replace the new battery, it should be replaced in time to avoid unnecessary troubles during driving. In fact, regular inspections can virtually save you money.

2. It is forbidden to be in a power-loss state. Storing the battery in a power-deficient state is prone to sulfation, and the lead sulfate crystals adhere to the plate, which will block the ion channel, resulting in insufficient charging and a decrease in battery capacity. In this case, the longer the idle time, the more severe the battery damage. To have a good battery, we should recharge it once a month.

3. Try to avoid large current discharge. When starting, going uphill, or carrying people, we should try to reduce the amount of slamming on the accelerator, because this will instantly discharge a large current and damage the physical properties of the battery plate.

4. It is forbidden to expose electric vehicles in the sun. An environment with excessively high temperature will increase the internal pressure of the battery and cause the battery to lose water, causing a decrease in battery activity and accelerating the aging of the plates.

5. Electric vehicles should be cleaned in accordance with normal car washing methods. During the cleaning process, more attention should be paid to the water flowing into the charging parts of the car body to avoid short circuit of the car body lines.

In summary, we can use and maintain lithium battery electric vehicles from these aspects to increase its service life.

The Difference Between a Lead-Acid Battery and a Lithium Battery for Electric Vehicles

The Difference Between a Lead-Acid Battery and a Lithium Battery for Electric Vehicles

/64 Comments/in /by

In today’s China, there are thousands of international famous brands of electric vehicles on the market at this stage, and the two factions of electric vehicles with lead-acid batteries and lithium batteries have their own characteristics and advantages. Although electric vehicles are rapidly transforming For so many years, many people have been confused about the choice of batteries for a long time, and they do not know what the difference between the two is. Well, today we will talk about the difference between lead-acid batteries for electric vehicles and lithium batteries for electric vehicles.

The difference between lead-acid and lithium battery electric vehicles.

1. The appearance design of lithium battery is better than that of lead-acid battery.

Lithium batteries need to be much smaller in size and quality than lead-acid batteries. In most cases, the total weight of lead-acid batteries is 16-30 kg, and the size is relatively large; while the total weight of lithium batteries is 3 in most cases. -3.0KG, the body is relatively small, so it is light for riding and convenient for shipping. In most cases, lithium battery electric vehicles are light and beautiful, easy to move, and many lithium battery electric vehicles can also be folded.

1. Durability and battery life:

The service life of lead-acid batteries is usually 2 years, while lithium batteries are more durable, with a lifespan of 4-5 years; and lead-acid batteries are usually fully charged and discharged within 300 cycles, while lithium batteries are fully charged and discharged. more than five hundred times.

2. Volume quality and ease of operation.

Compared with the lightweight body of only 2.5/3 kilograms of lithium batteries, lead-acid batteries of the same capacity usually weigh about 16/30 kilograms; not only the battery quality is relatively large, but also the volume; The disassembly design makes it more convenient and quick to carry.

3. Market price and cost performance.

At this stage, the mainstream lead-acid batteries on the market are about 450 yuan, while the price of lithium batteries is more expensive at 1,000 yuan; the prices of the two types of batteries are different, and the corresponding electric vehicle prices are also relatively different. At the same time, the warranty period of lithium battery is 1 year longer than that of lead acid, and the warranty period is 2 years.

4. Cruising range and battery capacity.

The same is a 48V battery. Under the condition of full power, the cruising range of lead-acid/lithium battery electric vehicles is almost the same. In fact, the key lies in factors such as speed and motor size. Naturally, lead-acid batteries will slightly exceed lithium batteries in terms of battery capacity.

In general, lead-acid batteries are the most numerous. The price of lead-acid batteries is the lowest and most common. China is the largest producer and exporter of lead-acid batteries in the world. It contains relatively few polluting components and has good recyclability. The disadvantage is that the specific volume is small. In other words, under the same capacity, the battery weight and volume are large. At this stage, most of the lead-acid batteries are transformed from floating charge batteries. Float rechargeable batteries reject fast charging and high-current discharge. Although professional and technical personnel have spent a lot of effort and made fruitful improvements, they can be put into practical use, but their lifespan is still very unsatisfactory. Which one is better depends on your own cost budget and needs. However, considering that after the announcement of the new national standard national policy, electric vehicles must be changed to the registered side before they can ride on the road normally, so it is best to choose an electric vehicle that meets the standard.

For batteries, the focus is often on capacity and energy density, and these data can often intuitively reflect the length of cruising range. But what we should note is that most batteries are electrochemical products. Since it is related to chemistry, its performance has a great relationship with temperature. Let’s first look at the effect of temperature on battery performance through data.

The capacity of the battery is most closely related to the cruising range. How much does temperature affect the battery capacity? It can be seen that when the discharge current is 100A, the battery capacity shrinks by 1.7% and 7.7% respectively from 20°C to 0°C and then to -20°C. This means that even if the temperature is as low as -20°C, the battery can still reach more than 90% of the nominal capacity. It can be said that the effect of temperature on battery capacity is relatively small. However, this does not mean that we can ignore the effect of temperature on the battery. According to the information provided by experts, under the condition that the charging current is 5A, the charging time at the ambient temperature of -25℃ is 63% slower than the charging time at 25℃.

Battery life is also a concern. According to the data, if a battery with a capacity of 3500mAh works in an environment of -10°C, after less than 100 charge and discharge cycles, the power will rapidly decay to 500mAh, and it will basically be scrapped. That is to say, in a working environment of -10°C, if you charge and discharge once, the battery will be scrapped and replaced after three months. This figure may be a bit exaggerated, but low temperatures do drastically shorten battery life.

Therefore, regarding the impact of low temperature on the battery, the conclusion is that although the low temperature environment has little effect on the discharge performance of the battery, it will seriously affect the charging performance of the battery and greatly shorten the life of the battery.

There are two main aspects to the battery technology winter solution for low temperature environment, one is the progress of battery technology, and the other is the maintenance of electric vehicle battery in winter.

For electric vehicle lithium battery maintenance methods in winter: In addition to relying on the technological progress of lithium battery factories, consumers can also perform winter maintenance of electric vehicle batteries through some simple methods. So how do you go about doing it? First, pay attention to the charging method, try not to charge the battery under low temperature conditions, and the same is true for high temperatures. When the high temperature exceeds 30 °C, the charging needs to increase the current input. Second, when charging in winter, you can use the method of charging several times. When the battery is charged, you can charge more at one time. Third, maintain a full power state. In winter, when the battery discharge exceeds 50%, the electrolyte will be in danger of freezing. Therefore, in winter, the battery should try to keep it above 50% of the power. Fourth, every other period Time to start the car, charge it, don’t let the battery discharge too much, don’t let the electric car sit outside for too long in the winter. In this way, I believe that our lithium battery electric vehicle will be safe this winter.
