Abstract
The first coating material adheres to the surface of the substrate to form a first layer. A first pressing force is applied to the first layer to compress the first layer. The second coating material adheres to the surface of the first layer after compression, thereby forming the second layer. A second pressing force is applied to the second layer to compress the second layer. An active material layer including a first layer and a second layer is formed. The second coating material is dry. The first coating material and the second coating material each independently include an active material and a binder.
Claims12
An electrode manufacturing method comprising:
- (a) forming a first layer by adhering a first coating material on a surface of a substrate;
- (b) compressing the first layer by applying a first pressing force to the first layer;
- (c) forming a second layer by applying a second coating material to a surface of the first layer after compression;
- (d) compressing the second layer by applying a second pressing force to the second layer;
- and
- (e) forming an active material layer including the first layer and the second layer,
- wherein the second coating material is in a dry state, and
- wherein the first coating material and the second coating material each independently include an active material and a binder.
An electrode comprising:
- a substrate;
- and
- an active material layer,
- wherein the active material layer is disposed on a surface of the substrate,
- wherein the active material layer includes a first layer and a second layer,
- wherein the first layer is disposed between the substrate and the second layer,
- wherein the second layer is in contact with the first layer,
- wherein the first layer and the second layer each independently include an active material and a binder, and
- wherein a surface of the first layer is flat at an interface between the first layer and the second layer.
