Are lithium batteries afraid of low temperatures? Military low-temperature lithium battery standards. Among all environmental factors, temperature has a significant impact on the charging and discharging performance of batteries, as the electrochemical reactions at the electrode/electrolyte interface are related to the ambient temperature. Currently, military low-temperature lithium batteries operate at temperatures as low as -50°C, but due to the special usage environment, military low-temperature lithium battery standards must adapt to certain conditions. Below, the editor from Seneng Electric will explain.
Are lithium batteries afraid of low temperatures?
Lithium batteries have characteristics such as large storage capacity, stable operation, and almost no memory effect. They also have advantages in adapting to environmental temperatures. For example, lithium thionyl chloride batteries can operate in a temperature range of -40°C to +55°C. However, when the temperature drops to -40°C, the capacity will also change to about 50% of that at room temperature. This indicates that low temperatures have a significant impact on lithium batteries, and they should be stored and used at room temperature as much as possible.
