Abstract

This invention provides a material for forming electrodes in non-aqueous secondary batteries, which exhibits excellent electrolyte durability (electrolyte resistance) and film-forming properties, and can form secondary batteries with excellent charge-discharge efficiency and capacity retention. This invention is a material for forming electrodes in non-aqueous secondary batteries, comprising core-shell particles (A) having a shell composed of polymer (a1) and a core composed of polymer (a2), and an aqueous medium (B). Polymer (a1) contains structural units derived from reactive emulsifiers, structural units derived from vinyl monomers with acidic groups, and structural units derived from (meth)acrylate monomers. Polymer (a2) contains structural units derived from vinyl monomers with crosslinking reactive groups and structural units derived from aromatic vinyl monomers. none
