Zn-based aqueous batteries (ZABs) hold great promise for large-scale energy storage applications due to the merits of intrinsic safety and low cost. Nevertheless, the thorny issues of metallic Zn anodes, including dendrite growth and parasitic side reactions, have severely limited the application of ZABs. Despite the encouraging improvements for stabilizing Zn anodes through surface modification, electrolyte optimization, and structural design, fundamentally addressing the inherent thermodynamics and kinetics obstacles of Zn anodes remains crucial in realizing reliable ZABs with ultrahigh efficiency, capacity, and cyclability. The target of this perspective is to elucidate the prominent status of Zn metal anode electrochemistry first from the perspective of zincophilicity and zincophobicity. Recent progress in ZABs is critically appraised for addressing the key issues, with special emphasis on the trade-off between zincophilic and zincophobic electrochemistry. Challenges and prospects for further exploration of a reliable Zn anode are presented, which are expected to boost in-depth research and practical applications of advanced ZABs.
锌基水系电池（ZABs）因其本质安全和低成本的优点，在大规模储能应用方面具有巨大潜力。然而，金属锌负极的棘手问题，包括枝晶生长和寄生副反应，严重限制了ZABs的应用。尽管通过表面改性、电解质优化和结构设计在稳定锌负极方面取得了令人鼓舞的进展，但从根本上解决锌负极固有的热力学和动力学障碍，对于实现具有超高效率、容量和循环稳定性的可靠ZABs仍然至关重要。本文的目的是首先从亲锌性和憎锌性的角度阐明锌金属负极电化学的突出地位。对ZABs在解决关键问题方面的最新进展进行了批判性评估，特别强调了亲锌和憎锌电化学之间的权衡。提出了进一步探索可靠锌负极的挑战和前景，有望推动先进ZABs的深入研究和实际应用。
