以交联聚丙烯酸钾和KOH水溶液为电解质制备了聚合物水凝胶电解质，组装成新型镍/锌（Ni/Zn）电池，并对其充放电特性进行了研究。与KOH水溶液相比，采用聚合物水凝胶电解质的实验Ni/Zn电池表现出良好的充放电曲线和显著改善的充放电循环性能。此外，有人发现，树枝状生长几乎没有发生在锌电极表面上的充放电循环期间的聚合物水凝胶电解质。这些结果表明，聚合物水凝胶电解质可以成功地用作Ni/Zn电池的电解质，具有优异的性能。
A new nickel/zinc (Ni/Zn) battery was assembled by using polymer hydrogel electrolyte prepared from cross-linked potassium poly(acrylate) and KOH aqueous solution, and its charge–discharge characteristics were investigated. The experimental Ni/Zn cell with the polymer hydrogel electrolyte exhibited well-defined charge–discharge curves and remarkably improved charge–discharge cycle performance, compared to that with a KOH aqueous solution. Moreover, it was found that dendritic growth hardly occurred on the zinc electrode surface during charge–discharge cycles in the polymer hydrogel electrolyte. These results indicate that the polymer hydrogel electrolyte can successfully be used in Ni/Zn batteries as an electrolyte with excellent performance.
