Abstract
A method of producing an electrode disclosed here includes a step in which a moisture powder formed of agglomerated particles; a step in which a coating film composed of the moisture powder is formed on an electrode current collector by using the moisture powder, with a gas phase of the coating film being remained, so that the average film thickness of the coating film is 50 μm or more; a step in which the coating film on the electrode current collector is transported, concavo-convex transfer is performed by using a roll mold, and thus a plurality of grooves extending in a direction orthogonal to a transport direction are formed on a surface part of the coating film so that a depth of the groove satisfies ( 9/10×t)>t, and a step in which the coating film formed on the electrode current collector is dried to form an electrode active material layer.
