TMAXCN Brand 18650/21700/26650/32650 Cylindrical Cell Lab Line Material Lithium Battery Preparation Material

18650/21700/26650/32650 Cylindrical Cell Lab Line Material Lithium Battery Preparation Material FeaturesThe main materials of lithium-ion battery include electrolyte, separator, anode and cathode materials, etc. The anode materials account for a large proportion (the mass ratio of anode and cathode materials is 3:1 ~ 4:1). Because the performance of anode materials directly affects the performance of lithium-ion batteries, the selection of high-quality battery materials plays a key role in batteries.Specification  TypeProduct NameMain FeaturesCathode Material for Li-ion BatteryLiCoO2 Powder 1. Formula:LiCoO22. Appearance: Black Powder3. Molecular Weight:97.884. First Discharge Capacity (mA/g) : 145 @1C5. Reasonable A-G Range: 6. 6.
