A V2O5 cathode for aqueous rechargeable Pb-ion batteries

Chem Commun (Camb). 2023 Oct 24;59(85):12719-12722. doi: 10.1039/d3cc04337a.

Abstract

Aqueous rechargeable metal batteries (AMBs) have attracted great attention and have been regarded as a next-generation promising energy storage system. However, the high-activity metal anodes usually face side reactions, passivation, and hydrogen evolution reactions, which impede the development of high-performance AMBs. Here, we designed and assembled a Pb metal battery based on a highly reversible Pb metal anode and layered V2O5 cathode, which showed good electrochemical performance. This new-type battery will encourage more investigations for high-performance AMBs and open up an innovation pathway for traditional lead-acid batteries.
