Abstract
A conductive composition for coating a current collector of coating a current collector for a battery or an electrical double layer capacitor, where the adhesion properties between a battery current collector and an active material layer are increased to improve the battery characteristics is presented. A battery using the battery current collector using the composition is also presented. The conductive composition for coating the current collector includes a vinylsilane copolymer, a polycarboxylic acid, and a conductive auxiliary. The formulation of the vinylsilane copolymer is also presented.
