1. Lithium batteries are divided by appearance: square (such as commonly used mobile phone battery cells) and cylindrical (such as 18650) lithium batteries;
2. Lithium battery with aluminum case, lithium battery with steel case, soft battery;
3. Lithium batteries are divided into positive and negative electrode materials (additives): lithium phosphate (LiCoO2) or lithium manganate (LiMn2O4) battery, lithium iron phosphate battery, disposable lithium manganese dioxide battery; another branch: lithium ion LIB, polymer PLB
IV. Divided into different performances and uses:
Disposable --- Lithium manganese battery. -- 3 volt coin cell battery
High capacity (high deck) -- used in digital mobile phone products
High rate --- used in electric cars, power tools and model airplaneses
High temperature; ---miner's lamp, interior lighting, built-in machine emergency power supply;
Low temperature ---outdoor environment, North (winter) Antarctica;
