Issues and opportunities facing aqueous zinc-ion batteries

摘要: Zinc-ion batteries built on water-based electrolytes featuring compelling price-points, competitive performance, and enhanced safety represent advanced energy storage chemistry as a promising alternative to current lithium-ion battery systems. Attempts develop rechargeable aqueous zinc-ion (ZIBs) can be traced early the 1980s; however, since 2015, research activity in this field has surged throughout world. Despite achievements made exploring electrode materials so far, significant challenges remain at material level even whole ZIBs system, leading failure of meet commercial requirements. This review aims discuss how pave way for developing ZIBs. The efforts related are summarized, including an analysis problems encountered both cathode/anode electrolyte optimization. Some concerns feasible solutions achieving practical discussed detail. We would like point out that merely improving is not enough; synergistic optimization strategies toward system also deeply needed. Finally, some perspectives provided subsequent design further ZIB field.
