CONDUCTIVE FILM, CURRENT COLLECTOR USING SAME, BATTERY AND BIPOLAR BATTERY.

摘要

This conductive film has a layer (1) formed by a conductive material (1) that contains conductive particles (1) and a polymeric material (1) containing any one of: (1) an amino and an epoxy resin (the mixing ratio of the epoxy resin and the amino is at least 1.0 in terms of the ratio of the number of active hydrogen atoms in the amino with respect to the number of functional groups in the epoxy resin); (2) a phenoxy resin and an epoxy resin; (3) a saturated hydrocarbon-based polymer having a hydroxyl group; and (4) a curable resin and an elastomer. The conductive film has excellent stability in an environment of equilibrium potential in a negative electrode, has low electrical resistance per unit area in the thickness direction, has excellent interlayer adhesion when used as a multilayer conductive film, and enables a battery that is both lightweight and durable to be obtained when used as current collector.
