ABSTRACT:
A method for forming an electrode for a battery includes the step of forming a porous layer on the surface of an electrode hoop formed at its surface with a mixture layer containing an active material. The porous layer is formed in the following manner: A gravure roll is rotated oppositely to the direction of movement of the electrode hoop while being allowed to abut against the surface of the moving electrode hoop, thereby applying a coating fluid serving as a precursor of the porous layer to the surface of the electrode hoop. A plurality of grooves formed in the circumferential surface of the gravure roll extend in parallel in oblique directions against the rotation direction of the gravure roll from the central line of the circumferential surface to the outer edges of the circumferential surface so as to be arranged in a symmetrical manner relative to the central line.
