| description | An electrode includes a current collector; a first active material layer including a first active material; and a second active material layer including a second active material; wherein the first active material layer is arranged between the current collector and the second active material layer. The first active material layer is formed on a surface of the current collector, and a particle size of 90% accumulative volume of the first active material is less than 40 μm. The active material layer is used to ensure that the electrochemical device and the electronic device do not generate a short circuit when pressed by an external force, thereby ensuring the mechanical safety performance of the electrochemical device and the electronic device. |
