Abstract
(a) An aerosol including an active material, a binder, and a gas is made. (b) A film-like flow of the aerosol is formed. (c) An electrically-charged region is formed by corona discharge. (d) The film-like flow passes through the electrically-charged region. (e) The film-like flow is introduced into an electric field after passing through the electrically-charged region. In the electric field, an active material layer is formed by adhering a solid component of the film-like flow onto a surface of a substrate by electrostatic force.

A method of producing an electrode for a lithium-ion battery, the method comprising:
- (a) making an aerosol including an active material, a binder and a gas;
- (b) forming a film-like flow of the aerosol;
- (c) forming an electrically-charged region by corona discharge;
- (d) allowing the film-like flow to pass through the electrically-charged region;
- (e) introducing the film-like flow into an electric field after passing through the electrically-charged region, and
- (f) applying at least one of heat and pressure to the active material layer to fix the active material layer to a substrate;
- wherein, in the electric field, an active material layer is formed by adhering a solid component of the film-like flow onto a surface of the substrate by electrostatic force.
