Abstract
A water-soluble binder useful for preparing an electrode for either primary or secondary batteries, having either aqueous or non-aqueous electrolyte, contains polyacrylamide and at least one copolymer selected from carboxylated styrene-butadiene copolymer and styrene-acrylate copolymer. The water-dispersible binder eliminates or reduces the need for organic solvents during preparation of an electrode made of a particulate active electrode material. The binder exhibits good chemical resistance, adhesive properties, flexibility and resilience, making it well suited for use in preparing batteries having a spirally wound electrode assembly.
