Abstract
A mixture of a polyolefin-based resin and a solvent is heated to a temperature at which at least part of the polyolefin-based resin melts to produce a viscous, gel-like adhesive solution. A mixture of the adhesive solution, an active material, and a conductive material is kneaded to produce a paste-form mixture, and a collector is coated with this paste-form mixture to form a mixture layer. The collector with the mixture layer formed thereon is then heated and dried, after which it is press-molded to a specific thickness and cut to a specific size to produce electrode plates.
