Low-cost, environment-friendly aqueous Zn batteries have great potential for large-scale energy storage, but the intercalation of zinc ions in cathode materials is challenging and complex. Herein, critical role structural H2 O on Zn2+ into bilayer V2 O5 ·nH2 demonstrated.

A zinc foil or sheet is the most common form of anode for aqueous ion batteries since it massively manufactured and readily accessible. Short circuits from dendrites grown on anodes can dramatically decrease cycling stability lead to premature failure batteries. Here, we show that manufacturing-induced defects, including surface imperfections such as a roughened surface, microcracks, scratches, fold lines, well unpolished edges cutting all promote local dendrite growth, leading drastically...
