Why do lithium batteries for electric vehicles and bicycles explode and catch fire? Analysis of various reasons

With the increasing awareness of environmental protection issues and the advancement of technology, lithium battery technology for electric vehicles and bicycles has developed into an important trend for us. However, in recent years,ESS battery machine incidents of lithium battery explosions and fires have become common, causing public concern about the safety of batteries. What are the reasons that lead to these tragedies?

1. The quality of the battery itself

Inferior batteries: There are a large number of inferior lithium batteries on the market. These batteries often use substandard raw materials and processes,Solid-state batteries causing the internal structure of the battery to be unstable and prone to safety problems such as short circuits and thermal runaway.

Battery aging: As the use time of lithium batteries increases, its internal structure will gradually age, its performance will decrease, and its safety will decrease. Aging batteries are more susceptible to thermal runaway and explosion.

2. Problems during charging

Overcharging: Overcharging is one of the common causes of lithium battery explosions and fires. When the battery is fully charged, continuing to charge it will cause the internal temperature and pressure of the battery to increase,sodium ion battery eventually leading to an explosion.

Excessive charging current: Using an inappropriate charger or charging cable will cause your own charging current to be too large, which will also increase the internal ambient temperature of the battery, causing safety management issues.

Poor charging environment: Charging in harsh environments such as high temperature and humidity can easily cause the internal structure of the battery to become unstable and cause safety issues.

3. Problems during use

Overloading: If an electric vehicle or bicycle is overloaded during use, the internal temperature of the battery will increase, causing safety issues.

Short circuit: A short circuit between the positive and negative batteries will generate a large amount of heat, causing the battery to explode and catch fire. A short circuit may be caused by external damage to the battery, damage to the internal structure, or faulty wiring.

Impact: An impact from an electric car or bicycle while driving may damage the internal structure of the battery and cause safety issues.

4. Problems during storage

Poor storage environment: Storing lithium batteries in harsh social environments such as high temperature and humidity can easily lead to instability in the internal control structure of the battery and information security management issues.

Long-term idling: Long-term idling of lithium-ion batteries may cause self-discharge, causing damage to the internal structure of the battery and reducing safety.

5. How to prevent explosion and fire in lithium battery technology?

Choose formal channels to purchase brand-name batteries: When purchasing lithium batteries, you should choose formal channels to purchase brand-name batteries and avoid purchasing inferior batteries.

Use the appropriate charger and charging cable: Use the original charger and charging cable for charging to avoid excessive charging current.

Follow correct charging techniques and methods: Follow a correct charging method to avoid bad charging habits such as overcharging and high-temperature charging.

Check the battery status regularly: Check the battery status regularly. If the battery is aging, damaged, etc., it should be replaced in time.

Correct use and storage of batteries: Avoid overloading and short circuiting during use; during storage, batteries should be stored in a dry and cool place.

In summary, there are many reasons for the explosion and fire of lithium-ion batteries, including the quality of the battery, the charging process, the use process and the storage process. In order to avoid tragedies, the safety issues of lithium batteries should be prevented from many aspects.
