The use of aqueous electrolytes and Zn metal anodes in Zn-based energy storage systems provides several benefits, including competitive density, excellent safety, low cost. However, dendrites growth slow ion transfer at the electrode/electrolyte interphase reduce cycle stability rate capability anode. Herein, V2O5-x interface layer was rationally controllably constructed on surface through situ spontaneous redox reaction between V2O5 layer, with an optimized thickness, plays a crucial role screening de-solvation, leading to uniform dispersion Zn2+ ions dendrite-free morphology. Moreover, as transports V element low-valence state allows oxygen anions bind more easily Zn2+. This interaction enables fast diffusion channel interfacial layer. Consequently, symmetric cells V@Zn achieve stable plating/stripping for than 1400 h 1 mA cm-2. In particular, full cell paired cathode exhibits capacity nearly 275.9 g-1 5 A after 2500 cycles without obvious deterioration, further highlighting potential practical applications.

Electrochemical are mostly comprised batteries, which outstanding advantages such as high density conversion efficiency. Among them, secondary batteries like lithium sodium lead-acid received wide attention recent years. Lithium-ion (LIBs) existed for a long time. However, due limited resources worldwide, uneven distribution, worrying safety issues, development LIBs has gradually hindered. Meanwhile, sodium-ion (SIBs), whose working principle is similar that LIBs, emphasized by researchers abundant low cost. Moreover, all-solid-state (ASSBs), higher density, simpler structure, stability safety, also under rapid development. Thus, SIBs ASSBs both expected play important roles applications.
