Hello:
Usually the temperature exceeds 60 degrees if it is not too high, the battery can still work, but the battery capacity will be affected. This will cause battery leakage and electrolysis. If the liquid leak disappears, the battery will definitely no longer be usable. The risk of explosion is not high. There is an overpressure safety valve inside the battery. If your using environment is harsh, you can consider using high temperature batteries, so don't worry too much about the ambient temperature.
What type of lithium battery can withstand high temperatures?
The suitable operating temperature of lithium polymer batteries is normal temperature (25 degrees Celsius ± 5), and the theoretical operating temperature is -40 to 70 degrees Celsius. The storage temperature conforms to the theoretical operating temperature.ilization (-40 to 70 degrees Celsius).
Lithium polymer batteries use file alloy as the positive electrode of the battery, polymer conductive materials, polyacetylene, polyaniline or polyparaphenol as the negative electrode of the battery, and the electrolyte uses organic solvents. The temperature limit of lithium polymer batteries is that because the electrolyte is made of colloidal material, no gas will be generated from inside the battery under high temperature conditions, thereby improving the safety of the battery .
Detailed informationLithium polymer batteries have the following characteristics and advantages:
1. Lithium polymer batteries have extremely high plasticity and can be made into thin batteries (the minimum thickness can be as thin as possible). like 0.5mm), can also be made into batteries of different shapes,greatly improving user portability.
2. The storage capacity of lithium polymer batteries has been significantly improved compared to previous lithium batteries. Theoretical data obtained from the production process shows that the storage capacity of lithium polymer batteries is 10% higher than that of lithium polymer batteries. ordinary lithium-ion batteries.

In lithium batteries, different types of lithium materials and electrolytes will affect the high temperature resistance of the battery . Here are some types of lithium batteries with better resistance to high temperatures:
1. Lithium iron phosphate (LiFePO4) battery: Lithium iron phosphate battery has high thermal stability and good high temperature resistance. up to 60-70 degrees Celsius.
2. Batterylithium titanate (Li-TiO2): Lithium titanate battery has higher thermal stability and can operate normally at temperatures up to 80 degrees Celsius.
3. Lithium iron oxide (LiFeO2) battery: Lithium iron oxide battery also has good high temperature resistance and can work normally in high temperature environments.
In addition, some new lithium battery technologies and improved electrolytes are also undergoing continuous research and development to improve the high temperature resistance of lithium batteries. However, even high temperature resistant lithium batteries may still be affected to some extent under extremely high temperature conditions. In practical applications, care must therefore be taken to avoid excessive exposure to high temperatures in order to protect performance andbattery safety.
