  "textContent": "An electrochemical apparatus formed by stacking and then winding a first separator, a negative electrode plate, a second separator, and a positive electrode plate. The negative electrode plate includes a negative electrode current collector, a first active material layer and a second active material layer. In a winding direction, a length of the first active material layer is greater than a length of the second active material layer. The first separator comprises a first substrate layer, a first coating layer and a second coating layer. The second separator comprises a second substrate layer, a third coating layer and a fourth coating layer. A bonding force between a first active material layer and a second coating layer is less than a bonding force between a second active material layer and a fourth coating layer.",
