Abstract

The invention discloses an electrode plate and a battery, and belongs to the technical field of batteries. The electrode plate comprises a polymer matrix, and the surface of the first side of the polymer matrix is provided with a first coating and a second coating which are laminated, wherein one of the first coating and the second coating is an active material layer, and the other one of the first coating and the second coating is a conductive coating. According to the electrode plate, a winding type battery cell and the battery provided by the invention, the energy density of the battery can be improved.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to an electrode sheet and a battery. Background technique [0002] At present, the electrode sheet of the wound battery usually includes a current collector, and the current collector is used as a carrier for coating the active material, which can facilitate the coating of the active material. However, due to the high mass ratio of the current collector in the entire battery cell, the energy density of the battery will be reduced to a certain extent. It can be seen that in the prior art, the battery has a problem of low energy density. Contents of the invention [0003] The electrode sheet and the battery provided by the application can improve the energy density of the battery. [0004] In order to solve the above-mentioned technical problems, the application is implemented as follows: [0005] In a first aspect, an embodiment of the present application provides an ...
