  "textContent": "The application discloses an electrochemical device and electronic device, including an electrode assembly. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator disposed between the first electrode plate and the second electrode plate. The first electrode plate includes a first active material layer and a second active material layer provided along the length of the electrode plate. A lithium ion diffusion rate of the first active material layer is greater than a lithium ion diffusion rate of the second active material layer. Thus, a lithium ion kinetic performance of the first active material layer is better than a lithium ion kinetic performance of the second active material layer, which can reduce the occurrence of lithium evolution.",
