Abstract

Rechargeable aqueous zinc-ion batteries (ZIBs) are regarded as a promising candidate for next-generation green energy storage systems owing to their high safety, low-cost, and low toxicity. Metal oxides with layered or tunnel structure are commonly applied as cathodes for ZIBs, but the electrochemical performance is severely limited by the structure collapse and sluggish diffusion kinetics. Preintercalating guest species into host structure is an effective strategy to solve these problems. Herein, a comprehensive overview on the recent developments of intercalation strategy in ZIBs is presented. The category and effect of guest species used in different cathode materials are presented. The issues and future research prospects in intercalation strategy are also discussed in this review.
