How much heat does the lithium battery tolerate?

I haven't found the answer to that question yet! The lithium battery we usually see is engraved with an explosion-proof valve. Because the battery pressure is too large at high temperatures, the explosion-proof Valve will work at this time. First, the explosion-proof Valve will open and the pressure will be released. The safety test of the battery also involves high temperature processes, such as 150 degrees hot box, 800 degrees iron plate, high temperature catapult  and so on to fail to explode. In fact, it is not rigorous, because the anti-explosion valve may not be able to be found on time, so there is also a saying that in how long it will not explode as a qualified standard.

In general, lithium batteries are tested at temperatures of 130 degrees, 150 degrees, 800 degrees, etc. However, under normal circumstances, they will not be exposed to such high temperatures at all in peacetime, but we sometimes see battery damage when charging or overusing electrical appliances situation. In particular, the recently heated smart device, the built-in bending battery, has 48 processes for safety testing alone, and the high-temperature project exceeds 50 degrees when the bending battery is converted. In daily life, such temperatures, bending batteries are unlikely to be touched.

While looking for bending batteries on Baidu, there is only one energy company found to explain the basic parameters of polymer lithium batteries (smart equipment bending batteries). Among them, the link to high temperature detection was discussed. I don't understand it. I only know that the bending battery process is very complicated. Finally, this special battery has eliminated the possibility of battery heat damage, and it will not explode. I don't know about the new bent batteries, and I find this kind of information is very poor, basically only some news, search for a bent battery, and only one company is doing it, which made me very headache.
