A High Power Rechargeable Nonaqueous Multivalent Zn/V₂O₅ Battery

Abstract

A beyond Li-ion battery based on Zn metal, aprotic electrolyte, and a hydrated bilayered V2O5 cathode with a large gallery spacing of 11–13 Å is introduced. The battery exhibits high 20 C rate capability with good specific capacity of 130 mA h g−1. This work provides some design rules for Zn intercalation behavior in host electrodes in a nonaqueous environment.
