What is the maximum temperature that a lithium battery can withstand?

As a new generation of energy storage technology, lithium batteries have been widely studied and used, but they can almost only work in room temperature environments. High temperature or low temperature will cause the performance of lithium battery to decrease. Especially under high temperature conditions, large heat fluctuations will occur inside, which may cause safety accidents such as explosions. The temperature limit set for mobile phone lithium batteries is generally 40-60 degrees, and the battery is generally marked with an explosion-proof valve, and the high-temperature lithium battery can withstand a high temperature of up to 800 degrees. Generally, lithium batteries can withstand high temperature detection, such as 200 degrees, 500 degrees and 800 degrees, but under normal circumstances, they will not be exposed to such high temperatures in daily life. Regarding lithium batteries, there is currently no clear theory in the industry to support the inevitable connection of internal resistance, discharge platform, life, and capacity under various temperature performance. The relevant calculation formulas and mathematical models are still in the groping stage. In general, lithium batteries are not sensitive to the temperature in the range of 0-40°C, but once the temperature exceeds this range, the life and capacity will be compromised. In order to ensure the life and safety and reliability of the lithium battery, the high temperature resistant lithium battery will adopt an advanced protection management system in the battery pack to guard against overcharging, overdischarging, high temperature operation, low temperature charging, or short circuit damage, and even safety problem.
