Abstract

A current collector for a battery includes: a layer () formed from an electrically conductive material and at least one of (a) a polymer compound having an alicyclic structure, (b) a saturated hydrocarbon polymer compound having a hydroxyl group, (c) a phenoxy resin and an epoxy resin, and (d) an amine having an amine equivalent of 120 g/eq or less and an epoxy resin; a layer () which is formed on at least one surface of the layer (); and a layer () formed from an electrically conductive material. The current collector for a battery has stability to an equilibrium potential environment in a negative electrode, a low electric resistance, a blocking property to solvent in electrolytic solution, and a blocking property to a component in an electrolyte. In addition, the current collector for a battery has a high capacity retention rate, and battery durability is improved.
