Fundamental Understanding and Effect of Anionic Chemistry in Zinc Batteries

With the merit of high capacity, safety, and low cost, zinc-ion batteries (ZIBs) possess huge application potential in domain large-scale energy storage. However, due to relatively narrow voltage window large lattice distortion cationic redox reaction, ZIBs tend present density, poor kinetics, unstable cyclic performance. Anion chemistry seems provide a novel strategy solve these issues from different aspects, such as enhanced operating voltage, extra capacity contribution, boosted reaction kinetics. Considering significance this theory lack relevant literatures, herein, in-depth comprehension anionic its positive effects on zinc storage performance have been emphasized summarized. This review aims full scope furnish systematic cognition for rational design advanced with density. Furthermore, insightful analysis perspectives based current research status also proposed, which may point out some scientific suggestions directions future research.
