The coated positive electrode roll

Key features and functions:

Energy storage: During charging, the active material undergoes lithium extraction; during discharge, lithium is inserted. This is the core of the battery's energy.

Conduction and ion transport: The conductive agent network transmits electrons, and the coating pores store electrolyte and transport lithium ions.

Processing adaptability: After drying, it has some flexibility and can be rapidly rolled (with a compression density increased to 3.2–3.8g/cm³), slit, without tearing or powder shedding.

Interface stability: The coating is strongly bonded to the aluminum foil, resistant to electrolyte corrosion, and does not fall off or bulge during cycling.
