摘要： An alkaline zinc secondary battery in accordance with the present invention comprises a separator layer comprising a gel electrolyte comprising a water absorbent polymer and an alkaline aqueous solution, disposed between a negative electrode comprising at least one selected from the group consisting of zinc and zinc oxide and a positive electrode. Because the separator layer is in a gel form, transfer of zinc ions is limited. Thereby, deformation of the negative electrode and generation of dendrite due to charge and discharge of the battery are substantially inhibited. Moreover, since impurity ions such as nitrate ions become less prone to move, self-discharge of the battery is also inhibited.
摘要翻译：根据本发明的碱性锌二次电池包括一个隔离层，该隔离层包含一种包含吸水聚合物和一种碱性水溶液的凝胶电解质，设置在包含选自锌和氧化锌中的至少一种的负电极和正极。因为隔离层是凝胶形式，锌离子的转移是有限的。由此，基本上抑制了由于电池的充放电引起的负极变形和枝晶的产生。此外，由于诸如硝酸根离子的杂质离子变得不容易移动，因此电池的自放电也被抑制。
