Abstract

PURPOSE:To prevent the damage of an anode in use due to deformation, expansion, cracks or the like, by subjecting a smallish pre-molded anode body to heat-treatment, then by secondary molding the pre-molded anode body to a certain size, by leaving the pre-molded anode body as it is. CONSTITUTION:An anode body is smallishly pre-molded in external diameter, smaller by 3-10% or so than that of an objective size; the specified sized anode body used can be produced by subjecting the pre-molded anode body to heat-treatment and then to secondary molding to form the aimed anode body or by leaving the pre-molded anode body as it is to form the aimed anode body. Here, a compression molded anode body made of anode materials, conductive agents (particularly, carbon powder, acetylene black), and binding agents is expanded after compression, after heat-treatment, and after impregnation with electrolyte. Considering this expansion, the anode body which was previously pre-molded smallishly and expanded by a specified treatment can be employed as the anode body 9 by secondary molding or by leaving as it is. Thereby, the damage of the anode body due to deformation expansion, cracks, or the like, can be prevented.
