Rechargeable Lithium Battery Performance and Testing
What are the main performance of the secondary battery /rechargeable lithium
battery
It
mainly includes voltage, internal resistance, capacity, energy density,
internal pressure, self-discharge rate, cycle life, sealing performance, safety
performance, storage performance, appearance, etc. There are also over-charge,
over-discharge, and corrosion resistance.
