Abstract Aqueous zinc‐ion batteries (AZIBs) are of interest in next‐generation energy storage applications owing to their safety, environmental friendliness, and cost‐effectiveness. Vanadium‐based oxides promising cathodes for AZIBs due appropriate structure multielectron redox processes. Although hundreds studies devoted understanding the mechanisms developing high‐performance vanadium‐based cathodes, many puzzles controversies still exist, especially regarding two representative by‐products, basic zinc salt (BZS) pyrovanadate (ZVO). BZS ZVO often observed on cathode anode during cycling, directly affecting battery performance. However, by‐products’ controversial unclassified insights unclear have severely limited Zn‐V batteries’ progress. Therefore, this review aims exhaustively elucidate “past present” by‐products following a logical sequence origin, role, inhibition strategy, prospect. Notably, incorporates substantial comments understandings long‐neglected issues related BZS‐related ZVO‐related dissolution mechanisms. This is expected provide scientific guidelines future optimization commercialization batteries.

Activating H₃O⁺ Intercalation Chemistry in Aqueous Zn‐VO₂(B) Batteries via Tungsten Doping and Oxygen Vacancies

Small, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

Vanadium-based materials have shone brightly in aqueous Zn metal batteries due to their high theoretical capacity and excellent high-rate capability. However, the severe vanadium dissolution attacked by H+ during cycling has persistently resulted unsatisfactory stability at low current density (generally ≤0.5 A g-1). To address this critical issue, a reversible H3O+ intercalation chemistry tunnel-structured VO2(B) is herein reported, which activated disordered substitution doping of V4+ W5+/6+ ions while simultaneously introducing oxygen vacancies. Both experiments calculations demonstrate that exhibits stronger adsorption energy on (110) plane synthesized W0.05V0.95O1.94(B) electrode than H+. Moreover, synergy between dopants vacancies can effectively improve distribution sites for H3O+, contributing an enhanced utilization surface-active sites. As result, cathode delivers specific 407 mAh g-1 0.1 maintains 357 with almost no decay after 100 cycles 0.5 g-1. These findings offer promising pathway developing rechargeable long-life vanadium-based cathodes.
