How to prevent spontaneous combustion of lithium-ion batteries in electric vehicles?

In order to prevent the spontaneous combustion of electric vehicles, it is necessary to pay attention to the safety of lithium-ion batteries. The national industry has been paying attention to a problem. Although the above-mentioned technology has made great progress, this kind of undesirable hidden danger still exists. Relevant experts pointed out that combustion and explosion are caused by various reasons. For example, a vehicle collision may cause the anode material of the battery to break the diaphragm, and the rapid charging of the brake energy may cause the battery to be short-circuited and the temperature rises, causing combustion or even explosion. At the same time, the organic electrolyte of lithium-ion battery electrolyte, these substances are more likely to be exposed to the air after a fire. At the lithium-ion battery forum, the general manager of synes energy technology compared gasoline batteries and lithium-ion batteries at the meeting. In principle, a tank of gasoline is safer than lithium-ion batteries. With lithium-ion batteries, battery energy storage batteries, the negative electrode is negative, immersed in a flammable electrolyte solution, and separated by only a 20-micron thick middle diaphragm, without any external conditions, the internal structure itself, the battery negative energy release Calorie combustion conditions, so the probability of safety problems for power lithium batteries is one in one million to one in ten million. Prior to this, due to the small number of electric vehicles, this probability was not significant, but the number of vehicles would be dangerous. The longer the battery life, the worse the safety. The difficulty facing the company lies in the probability of one in a thousand. It is difficult to draw safety conclusions using dozens of prototype vehicles and tens of thousands of kilometers of tests. At present, the country is vigorously promoting new energy electric vehicles and further unifying lithium-ion battery standards. However, in continuous improvement, the potential safety hazards of lithium-ion batteries still occur frequently in safety accidents, which also has a great negative impact on the promotion of electric trams.
