Provided in the present application are an electrode sheet and a lithium-ion battery including the same; the active layer of the electrode sheet includes a first layer and a second layer, wherein the first layer is disposed close to the current collector, the second layer is disposed on one side of the first layer which is facing away from the current collector, and the mass percentage of the binder in the first layer is greater than that of the second layer; by redistributing the binder, the peeling force and adhesion are ensured, and simultaneously the migration of the binder is improved; the influence of binder migration on uniformity and conductivity is reduced, thereby, the manufacturability and electrical properties such as energy density of the electrode sheet are improved.
An electrode sheet, comprising a current collector and an active layer disposed on the current collector, wherein the active layer comprises a first layer and a second layer, wherein the first layer is disposed close to the current collector, and the second layer is disposed on one side of the first layer which is facing away from the current collector, wherein a mass percentage of a binder in the first layer is greater than a mass percentage of a binder in the second layer.
