Lityum polimer piller uzun süre kullanıldıklarında feci arızalarla karşılaşabilirler. Bu yangınlar, piroforik sıvı elektrolitin aşırı ısınmasına ve kaynamasına neden olan hücre içindeki ekzotermik bir reaksiyon olan termal kaçaktan kaynaklanabilir. Bu süreç, tüketici elektroniği cihazlarında birçok durumda olduğu gibi, pilin muhafazasının patlamasına neden olabilir. Ancak neyse ki, bunun olmasını önlemeye yardımcı olmak için bu pillere yerleştirilmiş birçok güvenlik özelliği vardır.

One of the biggest dangers of lithium polymer batteries is the risk of fire. While lithium is not considered flammable, the anode material is, typically, graphite. However, the flammability of the battery’s electrolyte is comparable to that of gasoline. The solution for this potential hazard would be a non-flammable electrolyte, which would greatly reduce the risk of fire. Still, a large amount of heat is still required for a battery to catch fire.

While a lithium polymer battery can explode, it is unlikely that the ensuing fires will kill anyone. The main dangers of these batteries are the potential for short circuits, high temperatures, and improper storage. As a result, batteries must be tested regularly to ensure that they will not overheat and cause an accident. While some lithium polymer batteries can explode due to overcharging, most won’t.

Lityum polimer piller patlamasa da, arızalanmalarının yaygın bir nedeni aşırı şarjdır. Bu, pil hücrelerine yüksek voltaj uygulandığında meydana gelir. Normal lityum polimer piller için şarj voltajı 4,2V veya daha yüksek olmalıdır. Daha yükseği gaz ve ısı üretecek bir kimyasal reaksiyonu tetikleyecektir. Hücre duvarları şişerse, batarya sonunda patlayacak ve bir patlamaya neden olacaktır.

In the past, some lithium polymer batteries were known to explode at high temperatures. Fortunately, they never exploded in any way. The battery’s packaging was not the only cause of the explosions, which were caused by faulty cells. The outer packaging of a lithium polymer battery can be deformed and shattered, but a full-charged battery can still experience a dangerous explosion.

Another cause of battery explosions in lithium polymer batteries is the improper handling of the batteries. It is important to follow proper procedures to avoid this problem. For example, if you’re storing the batteries in an area with hot weather, be sure to store them in an area where temperatures will be low enough for the batteries to last for an extended period of time. This prevents accidents in your home, and is crucial for ensuring the safety of your family and your home.

1. Charge retention capability.
The charge retention capability is usually referred to as self-discharge, which usually refers to the retention capability of the battery stored in the corresponding environmental conditions in the open circuit state. Self-discharge is mainly determined by various factors such as lithium battery materials, manufacturing processes, and storage conditions. Generally, the higher the temperature, the greater the self-discharge rate. The corresponding degree of self-discharge of the rechargeable battery is a normal phenomenon
2. Internal resistance.
The internal resistance of a battery usually refers to the resistance to current flowing through the interior of the battery. The internal resistance of the rechargeable battery is very small, and it is necessary to use a special instrument to accurately measure the more accurate conclusion. Under normal circumstances, the internal resistance of the battery is the internal resistance in the charging state, even if the internal resistance of the battery is fully charged (corresponding to the internal resistance in the discharging state, which refers to the internal resistance after the battery is fully discharged. Generally speaking, the internal resistance in the discharging state The resistance is larger than the internal resistance in the charging state, and at the same time, it is not stable). The greater the internal resistance of the battery, the more energy the battery itself consumes, and the lower the battery’s use efficiency.
4. Capacity.
Refers to the total power that the battery can release under the corresponding discharge conditions.
5. Safety performance.
It is impossible to accept batteries with poor safety and reliability performance indicators. The most influential among them are explosions and leaks. The occurrence of explosion and liquid leakage is mainly related to the internal pressure, structure and process design of the battery, as well as incorrect operation.

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.

To recharge the 26650 LiFePO4 battery, you need to first understand how the battery works. Normally, this type of battery takes three to six hours to fully charge. There are different types of batteries, and different charging times. Some products do not have a built-in charger. Other brands sell the batteries separately. To determine which type of battery you should use, check the manufacturer’s manual.

Some of the most common types of 26650 batteries are INR and IMR. Choosing the right one depends on the battery type and application. IMR and INR batteries are better suited for motorcycles than unprotected ones. Nonetheless, protected 26650 batteries are more expensive and have smaller capacity than unprotected versions. It is best to check the instructions and follow them carefully.

To ensure proper battery performance, purchase batteries that have the same chemistry. You should avoid using older batteries that may not be compatible with current standards. Some of the latest models have protection features that prevent overcharging. Then, make sure you get a properly sized charger. This will protect your battery and prevent the battery from overheating. Also, the battery should fit into the compartment.

The 26650 battery can be used for motorcycles, and it has a long shelf life. The 26650 can deliver up to 20 Amps continuously and 40 Amps for a short period of time. However, you should avoid disassembling or incorrectly disposing of it. You should also make sure you do not expose the battery to extreme temperatures. If not, it can overheat and catch fire. Intelligent chargers are safe for the 26650 lithium ion battery packs. You can also find them online at affordable prices.

When charging the 26650 LiFePO4 battery, it is important to be careful when using the charger. It is possible to use the same charger for other batteries, but if the charger does not have the appropriate adapter, the battery may not work properly. The batteries should be charged with a USB port. This way, you can use the battery on the go without having to worry about damaging the batteries.

If you want to use the battery as a flashlight, you can use a charger that supports both types. It is important to use a suitable charger when using a 26650. The power of a lithium cell is determined by the current it can handle. If the voltage is higher, the longer the battery will last. In the case of an 18650, you will need to buy a new adapter for a new battery.

The 26650 LiFePO4 battery is a size C lithium battery that can be recharged. These batteries can be recharged by an intelligent battery charger. This charger uses a micro-USB port to identify the battery. It can be used in the same way as the standard 26650 battery. If you don’t have a dedicated charger, you can buy one that supports both of these types.

High-drain 26650 batteries have the ability to deliver up to 40 Amps continuously and 60-70 Watts for short periods of time. Due to their low internal resistance, the voltage drop is minimal. Therefore, a high-capacity battery will deliver up to 110-140 Watts. When recharging the 26650 LiFePO4 battery, it is essential to use a smart charger that can detect the battery condition and determine whether it is in good condition.

There are a few precautions when using a 26650 lithium-ion battery. This type of battery is the largest type and is used in a wide variety of electronic devices. This battery has a nominal voltage of 3.6 or 3.7 volts per cell and can deliver up to 20-30 Amps. The battery’s maximum charge voltage is 4.2 V, so be sure to use a charger that can handle this voltage range.

1. Prevent charging at too low temperature

If the lithium battery is used in a low temperature environment, that is, below 4C, the use time of the 26650 lithium ion battery will also be reduced, and the original lithium battery of some mobile phones cannot even be charged in a low temperature environment. But don’t worry too much, this is only a temporary situation, different from the use in a high temperature environment, once the temperature rises, the molecules in the battery are heated and immediately return to the previous power level.

2. Prevent charging at high temperature

If the 26650 lithium-ion battery is used in an environment higher than the specified operating temperature, that is, above 35C, the battery’s power will continue to decrease, that is, the battery’s power supply time will not be as long as usual. If the device is charged at such a temperature, the damage to the battery will be even greater. Even if the battery is stored in a hot environment, it will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a suitable operating temperature is a good way to extend the life of lithium batteries.

3. Frequent use

Life is movement. In order to maximize the performance of the 26650 lithium-ion battery, it is necessary to use it frequently so that the electrons in the lithium battery are always in a state of flow. If the lithium battery is not used frequently, please remember to complete a charging cycle for the lithium battery every month and do a power calibration, that is, a deep discharge and deep charge.
