1. Excessive charging leads to too much lithium release, and the negative pole capacity is insufficient. The lithium generated during the charging process cannot be inserted into the inter -layer structure of the negative polar graphite, and metal lithium will be formed on the negative surface. For a long time, lithium molecules will grow from the negative surface layer to the lithium -ion battery growth mesh crystal structure. This lithium metal crystal will cause a short -circuit failure through the membrane. Sometimes, the rechargeable battery will explode before the short -circuit failure, because raw materials such as lithium battery electrolytes will destroy the steam, causing the battery sleeve or pressure valve to rupture, causing carbon dioxide to react with the lithium atoms deposited on the negative surface layer, and then explode
2. When the battery is charged, the current limit is needed. When the current is too large, the lithium -ion battery cannot catch up with the upper structure and will gather on the surface of the positive electrode material. This lithium ion battery will generate lithium ion crystals on the surface of the raw material, just like over -charging, which will lead to risk factors
Therefore, in the lithium battery group, in addition to lithium batteries, there is also a lithium battery protection board, commonly known as BMS (battery management system), and the Chinese name is the intelligent management system of charging batteries. It can detect the lithium power supply according to the working voltage, current, and temperature information content of the lithium power supply.
Whether it is a pure electric car or an electric vehicle, it is not new for lithium ion safety accidents. During the old national standard, the lithium -ion application was small in the electric vehicle industry, and there were many safety accidents. The key reason is that the lithium battery battery is unstable, the packaging and processing technology are immature, and the habits of lithium ion application are very small. With the increase of lithium ions during the national standard period, if some countermeasures are not taken, the possibility of safety accidents is very high
