The energy storage prospects of zinc batteries

Zinc ion batteries (ZIBs) that use Zn metal as anode have emerged as promising candidates in the race to develop practical and cost-effective grid-scale energy storage systems. 2 ZIBs have potential to rival and even surpass LIBs and LABs for grid scale energy storage in two key aspects: i) earth abundance of Zn, ensuring a stable and affordable raw material source, and ii) high safety that is associated with the utilization of aqueous-based electrolytes and non-toxic Zn metal anode. 3 While LIBs hold great advantages in terms of their high working voltage and low self-discharge rate, the improvements for overall performance of ZIBs rely heavily on intensive studies.
