  • Patent number: 11637328
    Abstract: Development of a flexible battery based on periodate/iodate-zinc system is disclosed. H3PO4—KCl dual quasi-solid electrolytes separated by an anion-exchange-membrane maintain the desired pH in electrodes and block unwanted ion movements. Poly(acrylic acid) fortifies the electrodes, enhances electrode flexibility, and avoids the free-flow of liquids. The NaMnIO6 shows a specific capacity of 650 mAg?1, approximately 81% of its theoretical capacity even when cells are bent. The overall technology is scalable by printing methods.

  • Patent number: 8574742
    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.
