Electrode sheet of the battery cell

Type: The mutual conversion between chemical energy and electrical energy
Features: The battery electrode sheet is the core component of a battery, playing a crucial role in conducting electricity and facilitating electrochemical reactions. It consists of a positive electrode sheet and a negative electrode sheet, which are separated and connected by an electrolyte to form the electrochemical reaction area of the battery, enabling the conversion between chemical energy and electrical energy.
