Cylindrical Cell Assembly Pilot Lithium Battery Preparation Material For 18650 21700 26650 32650 Making


Features

The 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.
