Confined assembly of ultrathin dual-functionalized Z-MXene nanosheet intercalated GO nanofilms with controlled structure was realized for size-selective permeation.
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.
Layered vanadium-based oxides are regarded as promising cathode material for zinc-ion batteries (ZIBs), due to their open-framework crystal structure and high theoretical specific capacity. However, the sluggish Zn2+ diffusion and...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
