What is the operating temperature of lithium batteries?

Lithium batteries are divided into three categories: low temperature lithium batteries, normal temperature lithium batteries and high temperature lithium batteries. Needless to say, everyone knows about normal temperature lithium batteries. For example, our commonly used mobile phone batteries and mobile power supplies have a working temperature range of 0℃～60℃. Under normal circumstances, the temperature is about 45℃. If it exceeds It will be very hot at 50 degrees, and the battery will be easily aging and scrapped. High temperature resistant lithium iron phosphate battery High temperature lithium battery At present, the best high temperature resistant performance is the lithium iron phosphate battery. The high temperature resistance performance is 2 to 3 times that of other types of lithium batteries, and the peak value of electric heating can reach 350℃-500℃ , Compared with other types of lithium batteries, the temperature resistance performance of about 200 ℃ is significantly better, so lithium iron phosphate batteries are safer and more reliable in application. Regarding the operating temperature of low-temperature lithium batteries, the low-temperature batteries of Gripp batteries are representative in the industry. The parameters are as follows: (1) High low-temperature discharge performance, at least 0.2c discharge at -40°C, with an efficiency above 65%; Under the environment of 30℃, discharge at 0.2c, the discharge capacity is 85%; (2) Wide operating temperature range, -50C to 50C; (3) Excellent low temperature cycle performance, charge and discharge at 0.5c at -30℃, 300 After the second cycle, the capacity remains above 85%; (4) High safety performance and UL/CE/UN certification; (5) Flexible size, which can be designed and customized according to the size and shape of the customer; (6) With batch processing Ability, battery consistency is good; (7) Large current can be generated at -40°C, and large capacity can be maintained; (8) Excellent performance can still be maintained under -40°C working environment; Lithium battery working temperature is resistant to high temperature However, the lithium iron phosphate battery is the best. It can maintain battery performance at higher temperatures and ensure the operation of high-temperature electronic equipment. Therefore, many computer rooms use lithium iron phosphate batteries to provide temporary power supply. In terms of the low temperature resistance of lithium batteries, polymer lithium batteries are relatively good. They can withstand low temperatures -50C and can continue to discharge. They can be used in some special areas of electronic equipment to provide temporary backup power for low-temperature areas to ensure certain Work demands.
