How much high temperature can a high temperature lithium battery withstand?

How much high temperature can a high temperature lithium battery withstand? According to expert analysis, 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 are subjected to high temperature tests, such as 200 degrees, 500 degrees, and 800 degrees. However, under normal circumstances, we will not be exposed to such high temperatures in our daily life, but we can sometimes see charging or The battery is damaged when the appliance is overused. In particular, more and more smart devices are equipped with curved batteries. There are up to 50 safety monitoring procedures for safety detection alone. Among them, high-temperature items exceed 50 degrees when the curved battery is formed. In daily life At this temperature, it is unlikely that a bent battery will be exposed to it. Some large appliances and equipment require high-temperature lithium batteries. Because lead-acid is not environmentally friendly, it has low energy density, large size, short life span, and heavy weight. Nowadays, new products developed by merchants or batteries upgraded through transformation basically use high-temperature-resistant lithium batteries as the main power supply system of the equipment. . In order to ensure the life and safety and reliability of lithium batteries, advanced protection and management systems are used in the battery packs of high-temperature lithium batteries to prevent overcharging, overdischarging, high temperature operation, low temperature charging, or short circuit damage, and even safety problem. The service life of high-temperature lithium batteries is generally only two to three years. High-temperature lithium batteries can generally be charged and discharged 300-500 times. It is best to discharge the lithium battery partially rather than completely, and try to avoid frequent full discharge. Once the battery is off the production line, the clock starts to move. Regardless of whether you use it or not, the service life of lithium batteries is only two to three years. High temperature lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and can be charged. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are superior to those of lithium-ion batteries. Due to its own high-tech requirements, only a few companies in a few countries are producing this kind of lithium metal battery.
