When used for long periods of time, lithium polymer batteries can experience catastrophic failure. These fires can result from thermal runaway, an exothermic reaction within the cell, which results in overheating and boiling of the pyrophoric liquid electrolyte. This process can cause the casing of the battery to explode, as it has in many cases in consumer electronic devices. But luckily, there are many safety features built into these batteries to help prevent this from happening.

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.

While lithium polymer batteries may not explode, a common cause for them to fail is overcharging. This occurs when a high voltage is applied across the cells of the battery. For normal lithium polymer batteries, the charging voltage should be 4.2V or higher. Any higher will trigger a chemical reaction that will produce gas and heat. If the cell walls become swollen, the battery will eventually burst and cause an explosion.

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.

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.
