锌离子电池负极锌枝晶抑制的研究进展

Research Progress in Dendritic Inhibition of Negative Electrode Zinc for Zinc Ion Battery

近些年来,因为含有水电解液的锌离子电池(ZIBs)具有高安全性、环境友好性、低成本和高能量密度等优点而受到研究人员越来越多的关注。然而,锌离子电池负极的不稳定性阻碍了ZIBs在实际应用中的可靠部署。主要针对ZIBs负极存在的锌枝晶问题,先简单介绍了ZIBs的基本知识以及锌枝晶的发展。然后介绍了锌枝晶的形成和生长机理,并对锌枝晶的抑制策略从锌负极、电解液和隔膜三个方面在近年来的研究进展进行了综述。最后对锌枝晶抑制的三个方面进行了总结,并对未来在ZIBs负极锌枝晶抑制方面的研究方向进行了展望。

In recent years, zinc-ion battery(ZIBs) containing water electrolyte has attracted more and more attention because of its high safety, environmental friendliness, low cost and high energy density. However, the instability of the negative electrode of zinc-ion battery hinders the reliable deployment of ZIBs in practical applications. In this paper, the zinc dendrite existing in ZIBs negative electrode was discussed. The basic knowledge of ZIBS and the development of zinc dendrite were introduced. Then the formation and growth mechanism of zinc dendrite are introduced, and the inhibition strategies of zinc dendrite were reviewed from the aspects of zinc anode, electrolyte and diaphragm. Finally, the three aspects of zinc dendrite inhibition were summarized, and the future research direction of zinc dendrite inhibition in ZIBs anode was prospected.
