I haven't found the answer to this question yet! We usually see lithium batteries with explosion-proof valves engraved on them. Due to the excessive pressure inside the battery at high temperatures, the explosion-proof valve becomes effective. Firstly, the explosion-proof valve will open to release the pressure. In the safety testing of batteries, high temperature processes are also involved, such as a 150 degree heat box, an 800 degree iron plate, and high-temperature ejection. Non explosion is considered qualified. In fact, it is not rigorous because explosion-proof valves may not be able to be opened on time, so there is a saying that the qualified standard is based on how long it will not explode.

In general, lithium batteries can withstand high temperatures such as 130 ° C, 150 ° C, 800 ° C, etc. However, in daily life, they are not exposed to such high temperatures. However, we often see battery damage during charging or excessive use of electrical appliances. Especially with the recent popularity of smart devices, which have built-in curved batteries, there are 48 safety detection processes. Among them, high-temperature projects exceed 50 degrees Celsius when the curved battery is formed. In daily life, such temperatures are unlikely to be exposed to curved batteries.

When searching for bent batteries on Baidu, I only found one energy company that explained the basic parameters of polymer lithium batteries (smart device bent batteries), which discussed the process of high temperature detection. I don't understand it very well, but I only know that the bending battery process is very complex. Finally, I said that this special battery eliminates the possibility of high temperature damage to the battery and will not explode. I am not familiar with the new type of curved battery, and I have found that there is very little information in this area. Basically, there are only some news. When searching for curved batteries, only one company is doing it, which is very headache inducing.
