Lithium battery "refers to a type of battery made of lithium metal or lithium alloy as positive/negative electrode material, using a non-aqueous electrolyte solution. It can be seen everywhere in our lives, such as headphones, massagers, hydration devices. The safety of lithium batteries is crucial for us. Let's take a look at the testing items involved in lithium batteries
Performance testing items for primary and secondary batteries
Voltage, internal resistance, capacity, internal pressure, self discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc., as well as overcharge, over discharge, weldability, corrosion resistance, etc 2. Reliability Test Items
1. Cycle Life
2 Different rate discharge characteristics
3 Discharge characteristics at different temperatures
4 Charging characteristics
5. Self discharge characteristics
6. Self discharge characteristics at different temperatures
