摘要： The present invention comprises: a support formed in a grid; and a porous ion migration inhibition layer with which the grid of the support is coated and which has a plurality of pores formed therein, wherein each of the plurality of pores of the porous ion migration inhibition layer is formed so as to have a size smaller than the size of an electromigration-promoting ion contained in an electrolyte, whereby the electromigration-promoting ion does not pass through the porous ion migration inhibition layer. The present invention has an effect of preventing the performance of a zinc-air battery from being degraded in a manner whereby a plurality of pores in the porous ion migration inhibition layer of the separator are formed so as to have a size smaller than the size of potassium ions contained in an electrolyte, thereby preventing the potassium ions from migrating to a carbon layer to fundamentally prevent potassium hydroxide from being precipitated, whereby the carbon layer is destroyed. In addition, the present invention has an effect of allowing a zinc-air battery to be used as a secondary battery in a manner whereby potassium is prevented from migrating to the carbon layer, thereby preventing potassium hydroxide from being precipitated even when oxygen is moved to a positive electrode side during charging of the zinc-air battery. Furthermore, when the present invention is applied to a separator of an alkaline battery, it is possible to prevent potassium hydroxide from being precipitated during charging, thereby achieving an effect that an alkaline primary battery can be used as a secondary battery.
摘要翻译：本发明包括：形成在网格中的支撑件; 以及多孔性离子迁移抑制层，该多孔性离子迁移抑制层用于涂布所述支撑体的格子，并且其中形成有多个孔，其中所述多孔离子迁移抑制层的所述多个孔中的每一个孔形成为具有小于包含在电解质中的电迁移促进离子的尺寸，由此促电子迁移离子不通过多孔离子迁移抑制层。本发明具有防止锌 - 空气电池的性能劣化的效果，其中隔膜的多孔离子迁移抑制层中的多个孔形成为具有小于钾离子，从而防止钾离子迁移到碳层，从根本上防止氢氧化钾沉淀，由此碳层被破坏。另外，本发明具有如下效果：使锌空气电池作为二次电池以防止钾迁移到碳层的方式使用，由此防止氢氧化物即使在氧移动到在锌空气电池充电期间的正极侧。此外，当将本发明应用于碱性电池的隔膜时，可以防止氢氧化钾在充电过程中沉淀，由此实现碱性一次电池可以用作二次电池的效果。
