Original Abstract Submitted

An active material layer is provided with at least one first pore structure, and the active material layer satisfies the following conditions: (a) 0≤M/d≤0.5, where M is a mass percentage of the first active material in the active material layer, and d is a ratio of a depth of the first pore structure to a thickness of the active material layer; and (b) −1%≤0.2M−S≤3%, where S is a porosity of the active material layer. Adding the first active material with a larger gram capacity can increase the capacity of the electrochemical apparatus.
