1. Battery performance parameters
Capacity: Customized ultra-low temperature lithium batteries should have a high enough energy density to ensure stable power output under extreme conditions to meet the long-term operation needs of military equipment.
Self-discharge rate: The self-discharge rate of the battery during storage should be controlled at a low level to extend the service life of the battery.
Two, ultra-low temperature working environment
Operating temperature range: The battery should work normally in an ultra-low temperature environment of -60 degree C to -40 degree C, without performance degradation or failure.
Low temperature discharge performance: in the ultra-low temperature environment, the battery should have good discharge performance to ensure the normal operation of the equipment.
