Positive electrode sheet of the battery cell

Type: The mutual conversion between chemical energy and electrical energy
Features: The positive electrode sheet is one of the core components of a battery. Together with the negative electrode sheet, it forms the electrochemical reaction area of the battery, responsible for providing and receiving electrons during the charging and discharging process of the battery, and achieving the conversion between chemical energy and electrical energy.
