Abstract:
A method for manufacturing a positive electrode for an alkaline storage battery comprising:a first process of filling a paste of an active material for the positive electrode in a first porous metal sheet provided with a plurality of oblate pores whose major axes are arranged substantially in one direction; and a second process of pressing the first porous metal sheet that has undergone the first process using a roller press such that the one direction and a direction of a rotation axis of a roller in the roller press substantially are parallel, so as to produce a positive electrode sheet provided with a second porous metal sheet; wherein, in the second porous metal sheet, a value obtained by dividing a length of the pores in the one direction by that of the pores in a direction perpendicular to the one direction and parallel to a surface of the second porous metal sheet averages in a range of 0.9 to 1.1.
