    • 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.
    • 公开了使用设置在阳极和充电电极之间的高导电性聚合物固体凝胶膜分离器的可充电电化学电池。 分离器包括载体或底物和在其溶液相中具有离子种类的聚合物凝胶组合物。 在制备隔膜时,在聚合之前将离子物质加入到单体溶液中,并在聚合后保持嵌入所得的聚合物凝胶中。 离子物质表现为液体电解质,而同时基于聚合物的固体凝胶膜提供了光滑的不透明表面,其允许用于电池的放电和充电的离子交换。 有利地,分离器减少枝晶渗透并防止反应产物如金属氧化物扩散到电池的剩余部分。 此外,分离器的测量离子电导率远高于现有技术的固体电解质或电解质聚合物膜。 所公开的可充电电化学电池包括例如金属/空气,Zn / Ni,Zn / MnO 2,Zn / AgO,Fe / Ni和铅酸体系。

    • An electrolyte composition for zinc-based electrochemical cells that contains KOH and potassium acetate (KAcet) and/or soluble salts of cesium. 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.
