Abstract
Provided is a fabrication method of an electrode for a secondary battery including coating an electrode slurry containing an electrode active material and a binder on a current collector; drying the current collector on which the electrode slurry is coated to form an electrode active material layer; and surface-treating the electrode active material layer formed on the current collector to remove a binder layer on a surface of the electrode active material layer.
Claims10
A fabrication method of an electrode for a secondary battery, comprising the steps of:
- (a) coating an electrode slurry containing an electrode active material and a binder on a current collector;
- (b) drying the current collector on which the electrode slurry is coated to form an electrode active material layer;
- and
- (c) surface-treating the electrode active material layer formed on the current collector to remove a binder layer on a surface of the electrode active material layer.
An electrode for a secondary battery, comprising:
- a current collector;
- and
- an electrode active material layer positioned on at least one surface of the current collector and containing an electrode active material and a binder,
- wherein a content of the binder in a surface portion of the electrode active material layer is 0 to 1 wt % based on a total content of the binder in the electrode active material layer.
