Types of separators There are two broad classes of separators employed in nickel--zinc batteries. These are a main separator which exhibits resistance to dendrite penetration (dendristatic), and an interseparator which principally acts as an electrolyte reservoir and wicking layer.
Significantly, as the carrier of electrolyte and the bridge of ions, the separators show promising potential of inhibiting dendrites growth by regulating the ions migration and the electric field of the electrolyte-anode interface. However, a technical review about the separators of zinc ion batteries is still rare.
The separator acts as an effective and rapid channel for zinc ions to travel between the two electrodes and directly interacts with the electrode surfaces . The properties of separators significantly affect the mode of ion transfer and the deposition of Zn 2+; thus, the separator is crucial to the performance of ZIBs .
The widespread use of nickel—zinc batteries, particularly as electric vehicle power sources, would be strongly enhanced by significantly extending the deep-discharge cycle life beyond the current level of 100—300 cycles. p]The nickel—zinc battery's cycle life is governed in part by the properties of the battery separator system.

And these protrusions can act as nucleation sites for the formation of severe dendrites due to the uneven distribution of the electric field, leading to more uneven zinc ions deposition . The formed dendrites may pierce the separator and cause short circuit .
