報告摘要：Aqueous zinc-ion batteries (ZIBs) promise a few advantages: natural abundance and massive production; non‐toxic, easy and mature processing, high volumetric energy density, high stability and compatibility in aqueous electrolytes, and the two-electron-redox properties offer a high theoretical anode capacity. In spite of great progress made in recent years, some critical challenges remain to be addressed, such as dissolution of cathodes, formation of basic zinc salts, co-intercalation of protons, and large voltage gap of redox pairs. In this presentation, I will take vanadium pentoxide and hydrate vanadium pentoxide as model systems to demonstrate that the pre-insertion of cations and organic complex can effectively reduce the charge-discharge polarization, resulting in much enhanced storage capacity, and high energy conversion efficiency with excellent cycling stability. Various possible mechanisms for the enhanced electrochemical properties and battery performance are discussed.
