ABSTRACT:
Disclosed is a battery with a light weight and a high energy density. The battery includes a anode5, having a layer of an anode active material9formed on an anode substrate8, a cathode6, including a layer of a cathode active material14formed on a cathode substrate13, and a non-aqueous liquid electrolyte4. The anode substrate8includes an anode resin film11containing a polymer and an anode metal layer12containing an electrically conductive metal. Since the anode resin film11reduces the weight of the anode substrate8and the anode metal layer12imparts electron conductivity to the anode substrate8, the battery may be reduced in weight without detracting from battery characteristics to increase the energy density.
