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.
Claims4
A method for manufacturing electrode plates for a battery, comprising:
- mixing a solvent into a polyolefin-based resin used as a binder;
- heating the mixture of the polyolefin-based resin and the solvent at a temperature at which at least part of the polyolefin-based resin will melt, thereby producing a viscous, gelled adhesive solution;
- kneading a mixture of a conductive material, a battery active material, and the gelled adhesive solution to produce a paste mixture;
- coating a collector with the paste mixture to form a mixture layer;
- heating and drying the collector on which the mixture layer is formed;
- and
- press-molding the mixture layer to a specific thickness.
