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.

Abstract: An electric field is formed between a substrate and a screen by applying a first voltage to the substrate and applying a second voltage to the screen. Coating powder is introduced into the electric field through the screen. An electrode is manufactured by causing the coating powder to adhere to the substrate. The first voltage has a polarity opposite to a polarity of the second voltage. When the coating powder passes through the screen, the coating powder comes into contact with the screen to apply a charge to the coating powder. The coating powder flies in the electric field by an electrostatic force to reach the substrate. An angle between a flight direction of the coating powder and a vertically downward direction is 90 degrees to 270 degrees.

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.

Abstract: An aerosol including an active material powder, a binder, and a gas is prepared. An electric field is formed between a substrate and a porous electrode. The aerosol is electrically charged. The aerosol after the electrically charging is introduced into the electric field. The aerosol passes through the porous electrode and thereby the aerosol is introduced into the electric field. At the time of the aerosol passing through the porous electrode, the aerosol comes into contact with the porous electrode and thereby the aerosol is electrically charged. In the electric field, the aerosol after the electrically charging flies toward the substrate due to electrostatic force. The aerosol adheres to a surface of the substrate and thereby an active material layer is formed.

Abstract: Granules including an active material powder and a binder are prepared. The granules are supplied onto a surface of a roller. The granules are electrically charged. The granules are transferred from a first region to a second region by way of rotation of the roller. A first electric field is formed between the second region and a third region to allow the granules to fly from the second region toward the third region. A second electric field is formed between the third region and a substrate to allow the granules to fly from the third region toward the substrate.
