Abstract
The method for producing a secondary battery electrode disclosed here includes steps of: preparing a moisture powder formed by aggregated particles that contain electrode active material particles, a binder resin, and solvent, wherein a solid phase, liquid phase, and gas phase in at least 50 number % or more of the aggregated particles in the moisture powder form a pendular or funicular state; forming a coating film composed of the moisture powder, on an electrode current collector, while the gas phase remains present; carrying out depression/elevation transfer into a surface part of the coating film; forming an electrode active material layer by drying the coating film; and pressing the electrode active material layer. The electrode active material particles are aspherical particles in which a ratio of a short side to a long side in a cross sectional view is less than 0.95.
