Abstract
An electrochemical device includes a positive electrode, the positive electrode includes a current collector and a film layer containing a positive active material. The film layer is disposed on at least one surface of the current collector. The positive active material includes a primary particle and/or a secondary particle. When a mass percent A of the primary particle in the positive active material based on a mass of the positive active material satisfies 20%≤A≤100%, the film layer, the positive active material, and the current collector satisfy: D≥Dv−D; and, when a mass percent A' of the primary particle in the positive active material based on the mass of the positive active material satisfies 0≤A′≤20%, the film layer, the positive active material, and the current collector satisfy: D≥1.1 Dv.
