Abstract
A method of manufacturing a battery electrode includes a powder supply step, a vibration step, a sorting step, a moving step, and a deposition step, in the powder supply step, a powdercomposed of granulated particles is supplied, in the vibration step, vibration is applied to the powder, in the sorting step, the powder is caused to pass through at least one opening H, Hto adjust a particle diameter of the granulated particles to a particle diameter that allows passing through the opening, in the moving step, the powder that has passed through the opening is moved from an outlet position Pof the opening to a supply position Pwhere the powder is supplied to the surface of a current collector, and in the deposition step, the powder is deposited on the surface of the current collector. With the method of manufacturing a battery electrode, it is possible to provide a battery electrode that can improve battery performance by making a thickness and a density of the powder composed of granulated particles supplied onto the current collector uniform.
