Reliable lateral Zn deposition along (002) plane by oxidized PAN separator for zinc-ion batteries.

ABSTRACT: Aqueous zinc ion batteries (AZIBs) are the promising candidate for energy storage where safety and low cost are the major concerns. However, the uneven and random electrodeposition of Zn has become a serious impediment to the deep recharging of AZIBs. Conventional modifications on zinc substrate can promote homogenous zinc deposition initially, but not sustainably. Here, an oxidized polyacrylonitrile (OPAN) membrane with a conjugated planar structure is proposed as a zinc ion battery separator. This separator can continuously regulate the growth of Zn with (002) texture to inhibit dendrites. In addition, the separator has a fast Zn²⁺ ion transfer, which can spontaneously repel SO₄^2- and relieve side reactions. As a result, the Zn-symmetric batteries show cy
