Abstract
A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.
