    摘要： Rechargeable electrochemical cells that employ a highly conductive polymer-based solid gel membrane separator disposed between the anode and charging electrode are disclosed. The separator comprises a support or substrate and a polymeric gel composition having an ionic species contained in a solution phase thereof. In preparing the separator, the ionic species is added to a monomer solution prior to polymerization and remains embedded in the resulting polymer gel after polymerization. The ionic species behaves like a liquid electrolyte, while at the same time, the polymer-based solid gel membrane provides a smooth impenetrable surface that allows the exchange of ions for both discharging and charging of the cell. Advantageously, the separator reduces dendrite penetration and prevents the diffusion of reaction products such as metal oxide to remaining parts of the cell. Furthermore, the measured ionic conductivity of the separator is much higher than those of prior art solid electrolytes or electroyte-polymer films. The disclosed rechargeable electrochemical cells include, for example, metal/air, Zn/Ni, Zn/MnO2, Zn/AgO, Fe/Ni, and lead-acid systems.

    摘要： A separator for zinc electrode-based cells that is effective in preventing dendrite growth in a zinc rechargeable cell is prepared as A standalone membrane, or as a composite membrane by impregnating the membrane into a nonwoven fabric. Interpenetrating polymer networks are employed by combining two different polymers. The two polymers penetrate each other on a molecular scale so that mechanical strength, water content and conductivity of the membranes can be effectively optimized. Since the water content of membrane can be optimized by introducing high water content polymers other than polyvinyl alcohol, wherein the diffusion of water from the separator membrane when the membrane contacts alkaline electrolyte solution can be largely reduced. Such membranes demonstrate excellent dendrite blocking capability in a practical zinc rechargeable cell.

    摘要： A solid-state hydroxide (OH−) conductive membrane provides up to five times higher ionic conductivity and surface oxygen exchange rate than conventional MIEC membranes, while operating at significantly lower temperatures and providing reduced overall system cost. The hydroxide conductive membrane utilizes a porous ceramic backbone, pores of which are injected with an electrolyte. A catalyst is provided as discrete layers disposed at the anode and cathode. The membrane of the present invention may be utilized in combination with an external voltage source to drive the oxygen generating reaction. Alternatively, the pores may be metallized and a pressure gradient utilized to drive the reaction. The membrane thus provides discrete materials to provide ionic conduction, electronic conduction, and structural support.

The electrolyte significantly eliminates shape change and dendrite growth while retaining high ionic conductivity. Anticorrosion compounds such as soluble indium compounds may be included alone or in combination with auxiliary anticorrosion compounds such as soluble tin compounds to improve charged stand and shelf life. Optionally, lithium hydroxide may be added to the electrolyte to facilitate charge acceptance of the positive electrode, particularly at cold temperatures.
