Abstract

This invention provides a battery forming composition with improved adhesion. Specifically, a battery forming composition includes an adhesive resin and an adhesion modifier, wherein the adhesion modifier is a polyester represented by the following general formula (1-1), general formula (1-2), or general formula (1-3) (G is an aliphatic diol residue with 2 to 50 carbon atoms, A is an aromatic dicarboxylic acid residue with 4 to 18 carbon atoms, X is a monocarboxylic acid residue with 1 to 20 carbon atoms, Y is a monool residue with 1 to 30 carbon atoms, and n represents the repeating number).
