摘要
基于锌的水基液流电池在未来电网规模的能源存储方面受到极大关注，但锌阳极不可控的枝晶生长和有限的电镀电流密度严重阻碍了其应用前景。在本文中，我们通过施加外部磁场，在 100 mA cm-2 的超高电流密度下实现了非树枝状锌生长。通过原位观察、形态表征和电化学性能探索，我们发现磁场能有效抑制树枝状的野蛮生长。我们相信这项工作能为高倍率锌金属阳极的研究提供新的启发，并促进锌基液流电池的未来应用。
Magnetic Field Enabled Ultrahigh-Rate Zn Metal Anodes
Aqueous Zn-based flow batteries receive tremendous attention toward future grid-scale energy storage, but the uncontrollable dendrite growth and limited plating current density at the Zn anode severely hinder their application prospects. Herein, we realize non-dendritic Zn growth at an ultrahigh current density of 100 mA cm-2 via the application of an external magnetic field. Through in-situ observation, morphology characterization, and electrochemical performance explorations, we find that the magnetic field can effectively inhibit the savage growth of dendrites. We believe this work can provide new inspiration for high-rate Zn metal anode research and promote the future applications of Zn-based flow batteries.
