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;
Absolutely not. Lithium batteries are divided into lithium-cobalt-phosphate systems, lithium-iron-phosphate systems, etc. Among them, the lithium cobalt phosphate system has high capacity, but it is generally easy to explode. , high-capacity mobile phones and Tesla cars all use this system. Once the outer cover is broken, it should be replaced and the battery should not be thrown away casually and disposed of properly. Otherwise the consequences will be serious
