  • Publication number: 20110165447
    Abstract: The printed battery has cathode and anode electrodes with terminals to connect to an external circuit, separator therebetween and electrolyte. An anode electrode material is applied on one side of the separator and a cathode electrode material on the opposite side. The anode material is dry and hydrophobic and is prepared by providing an anode active material, conductive material, solvent and a binder that are mixed to form an anode ink. The anode ink is applied on a substrate and then dried. In response to the drying, the solvent evaporates and the anode ink forms a film on the substrate. The prepared anode material is applied on the separator. An electrolyte solution is printed on the separator that has the anode material thereon. A cathode material is applied between a collector material and separator.

  • Patent number: 7901807
    Abstract: A band-shaped laminate having a flexible elongated substrate, a negative collector, a solid electrolyte, a positive active material, and a positive collector in this order is wound in a plate shape with the flexible elongated substrate placed inside. The band-shaped laminate that is laminated in a particular order is wound with the substrate placed inside, whereby a short-circuit occurrence ratio can be decreased. Furthermore, the band-shaped laminate includes the solid electrolyte, and is wound in a plate shape, whereby the reduction in thickness and the increase in volumetric energy density can be achieved.
