A VO cathode for aqueous rechargeable Pb-ion batteries

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...

Description
Summary: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 V 2 O 5 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. A rocking-chair Pb metal battery based on highly reversible plating/stripping Pb metal anode and layered intercalation/deintercalation V 2 O 5 cathode in aqueous electrolytes with Pb 2+ as the charge carrier is reported showing good performance.
