How does the temperature of a high-temperature battery affect battery performance?

The temperature of high-temperature batteries can have a significant impact on their performance. Typically, high-temperature batteries are designed to operate at high temperatures, typically between 60 ° C and 120 ° C, to achieve higher energy and power density.

At higher temperatures, the chemical reactions occurring within the battery can proceed faster, resulting in higher current output and higher energy density. However, if the temperature is too high, the battery may be damaged and performance may deteriorate.

Some effects of temperature on the performance of high-temperature batteries include:

Capacity: The capacity of high-temperature batteries will decrease at high temperatures. This is due to an increase in the rate of chemical reaction, which may lead to faster degradation of the battery active material.

Cycle life: The number of charging and discharging cycles a high-temperature battery can experience before its capacity decreases will also decrease at high temperatures.

Power output: High temperature batteries can provide higher power output at higher temperatures. This is due to the low internal resistance of the battery at high temperatures.

Safety: High temperature batteries are more prone to thermal runaway and other safety hazards at high temperatures, especially in the case of improper design or operation.
