  "textContent": "An electrochemical device includes a negative electrode sheet. The negative electrode sheet includes a current collector, a first coating layer, and a second coating layer. The first coating layer is located between the current collector and the second coating layer. The second coating layer includes a negative active material. The first coating layer includes a conductive carbon material. The conductive carbon material includes at least one of carbon nanotubes or graphene. Based on a mass of the first coating layer, a mass percent of the conductive carbon material is 20% to 60%. The main material of the first coating layer is at least one of carbon nanotubes or graphene.",
