| abstract | Embodiments of the present application provide electrochemical devices and electronic devices. The electrochemical device includes a negative pole piece, the negative pole piece includes a negative electrode current collector, a first layer and a second layer, and the first layer is located between the negative electrode current collector and the second layer; wherein, the first layer includes a first negative electrode active material, The second layer includes a second negative active material; the first negative active material contains a first doping element, and the second negative active material contains a second doping element; the mass of the first doping element in the first layer The percentage is greater than the mass percentage of the second doping element in the second layer, the first doping element and the second doping element are of the same type, and the first doping element and the second doping element each independently include At least one of S, N, P, B, Sn or Sb. In this way, while improving the energy density of the electrochemical device, the adverse effect on the fast charging performance is reduced. |
