Aqueous zinc-ion batteries (AZIBs) are considered as the promising candidates for large-scale energy storage because of their high safety, low cost and environmental benignity. The large-scale applications of AZIBs will inevitably result in a large amount of spent AZIBs, which not only induce the waste of resources, but also pose environmental risks. Therefore, sustainable AZIBs have to be considered to minimize the risk of environmental pollution and maximize the utilization of spent compounds. Herein, this minireview focuses on the sustainability of AZIBs from material design and recycling techniques. The structure and degradation mechanism of AZIBs are discussed to guide the recycling design of the materials. Subsequently, the sustainability of component materials in AZIBs is further analysed to pre-evaluate their recycling behaviors and mentor the selection of more sustainable component materials, including active materials in cathodes, Zn anodes, and aqueous electrolytes, respectively. According to the features of component materials, corresponding green and economic approaches are further proposed to realize the recycling of active materials in cathodes, Zn anodes and electrolytes, respectively. These advanced technologies endow the recycling of component materials with high efficiency and a closed-loop control, ensuring that AZIBs will be the promising candidates of sustainable energy storage devices. This review will offer insight into potential future directions in the design of sustainable AZIBs.
水系锌离子电池（AZIBs）因其高安全性、低成本和环境友好性而被认为是大规模储能的有前途的候选者。AZIBs的大规模应用将不可避免地产生大量废旧AZIBs，这不仅会导致资源浪费，还会带来环境风险。因此，必须考虑可持续的AZIBs，以尽量减少环境污染风险并最大限度地提高废旧化合物的利用率。在此，本综述聚焦于从材料设计和回收技术方面探讨AZIBs的可持续性。讨论了AZIBs的结构和降解机制，以指导材料的回收设计。随后，进一步分析了AZIBs中组成材料的可持续性，以预先评估它们的回收行为，并指导选择更具可持续性的组成材料，分别包括阴极活性材料、锌阳极和水系电解质。根据组成材料的特点，进一步提出了相应的绿色经济方法，以分别实现阴极活性材料、锌阳极和电解质的回收。这些先进技术使组成材料的回收具有高效率和闭环控制，确保AZIBs成为可持续储能装置的有前途的候选者。本综述将为可持续AZIBs设计的潜在未来方向提供见解。
