Aqueous zinc metal batteries (ZMBs) are considered promising candidates for large-scale energy storage. However, there are still some drawbacks associated with the cathode, zinc anode, and electrolyte that limit their practical application. In this Focus Review, we focus on unveiling the chemical nature of aqueous ZMBs. First, cathode materials and electrochemical reactions are summarized and discussed. Then, fundamental understanding of zinc plating/stripping chemistry is presented, followed by the principle of zinc-dendrite growth and hydrogen evolution as well as the corresponding mitigation strategies. After that, electrolyte engineering, mainly considering salts, concentration, additives, and hydrogel electrolyte, is discussed. Finally, the remaining challenges of aqueous ZMBs toward practical application are noted, mainly including the undefined mechanism and dissolution of the cathode, dendrite growth and hydrogen evolution of the zinc anode, equilibrium between performance and cost of the electrolyte, and testing protocols of full cells. This Focus Review provides new insights for further research and development of aqueous ZMBs.

水性锌金属电池中的储能化学

水性金属锌电池（ZMB）被认为是大规模储能的有希望的候选者。然而，仍然存在与阴极，锌阳极和电解质有关的一些缺点，这些缺点限制了它们的实际应用。在本重点回顾中，我们着重于揭示水性ZMB的化学性质。首先，总结和讨论了阴极材料和电化学反应。然后，介绍了对镀锌/剥离化学的基本理解，然后介绍了锌-枝晶生长和析氢的原理以及相应的缓解策略。之后，讨论了主要考虑盐，浓度，添加剂和水凝胶电解质的电解质工程。最后，指出了ZMB水溶液在实际应用中的剩余挑战，主要包括阴极的不确定机理和溶解，锌阳极的枝晶生长和氢逸出，电解质的性能和成本之间的平衡以及完整电池的测试方案。本重点回顾为水性ZMB的进一步研究和开发提供了新的见解。
