Abstract
An electrochemical apparatus includes an electrode plate, where the electrode plate has a current collector and an active material layer disposed on at least one surface of the current collector, the active material layer has at least one pore, and an included angle between an axial direction of the at least one pore and a plane on which a surface of the active material layer lies is θ, where θ°≤θ<90°. This improves efficiency of the electrode plate in infiltration and absorption of the electrolyte, thereby improving rate performance, cycling performance, safety, stability, and other qualities of the electrochemical apparatus.
