报告摘要：

Lithium-ion battery and sodium-ion battery have been applied in energy storage devices, but low safety factor owing to the active chemical properties of Li⁺ and Na⁺ encourage us to develop new battery chemistry. As a safe, cost-effective and pollution-free device, rechargeable aqueous zinc-ion battery (ZIBs) shows desirable potential as alternative to LIBs and SIBs, and it is considered to be more feasible for grid-scale applications. Recently, lots of work has been done to develop new cathode materials and zinc storage insights for rechargeable aqueous ZIBs. However, the proposed energy storage mechanisms in aqueous ZIBs are still complicated and unclear. In this talk, the crystal structure and electrochemical mechanism of some typical cathodes in aqueous ZIBs will be described. The relationship between the structure, composition, storage mechanism and the electrochemical properties will be discussed in detail.
