1. According to the classification of electrode materials

　　Battery positive material: lithium iron phosphate battery (LFP), lithium cobalt oxide battery (LCO), lithium manganese oxide battery (LMO), (binary battery: lithium nickel -manganese oxide lithium nickel cobalt oxides), triple yuan Battery: lithium nickel cobalt and manganese oxide battery (NCM), lithium nickel cobalt aluminum aluminum battery (NCA))

　　Negative materials: lithium titanate batteries (LTO), graphene batteries, nano -carbon fiber batteries.

　　In the sales market, the key to the concept of graphene is to use graphene -based rechargeable batteries, that is, add graphene base materials to polar TV series or add graphene base coating on the diaphragm. There will be no foundation for the sales market for lithium nickel and magnesium -based rechargeable batteries.

　　2. Classified by product appearance

　　Divided into: cylindrical, soft bag and square

　　The cylindrical and square packaging is usually made of steel or aluminum. The outer packaging of the soft bag is an aluminum -plastic film. In fact, soft bags are also square. The aluminum -plastic packaging used in the sales market is called a soft bag. Some people call the soft bag battery a polymer lithium battery.

　　For lithium ion battery models, it is a universal 5 -bit specification. The first two are direct numbers and intermediate numbers of rechargeable batteries. The company is MM. For example, 186 lithium ions are 58 mm wide and 65 mm high.

　　3. Depending on the electrolyte material, lithium batteries are divided into liquid lithium batteries (LIB) and polymer lithium batteries (PLB)

　　Liquid lithium batteries are used for liquid electrolytes (mainly used for electric rechargeable batteries). The polymer lithium battery is replaced by the electrolytic solution of the solid polymer, and the electrolytic solution of the solid polymer can be dry or colloid. At present, most of the polymer electrolyte solution. For solid -state batteries, the exact meaning is that the liquid level and electrolyte are solid.

　　4. Classification by battery performance

　　Outputable rechargeable batteries and rechargeable batteries. Dynamic rechargeable batteries have the characteristics of high -efficiency energy relative density, and the key is that high -efficiency energy discharge. The output power of lithium ion power increases with the emergence of hybrid electric vehicles. It requires a rechargeable battery to store high power, which can be used for pure electric vehicles that distance. It also has good output power characteristics and enters the hybrid mode of oil and electricity under low power consumption mode.

　　It is not difficult to understand. Similar to the marathon athletes, the type of kinetic energy with physical fitness is to adjust the charging and discharge special of large capacity and large current; then the type of output power is a sprinter, which has strong combat effective The capacity runs close.
