摘　　要：目前,水系锌离子电池(AZIBs)的正极材料已取得了许多引人瞩目的突破,但普遍存在结构稳定性差、易溶解、材料骨架间存在严重的静电相互作用和导电性差等亟待解决的问题,需要进一步地研究和取得关键性技术的支持。MnO_(2)作为AZIBs正极材料的储能机制较其他材料复杂且一直存在争议,是限制Zn//MnO_(2)电池应用的主要因素。该文总结了最新MnO_(2)基正极材料的特征和储能机制,回顾了MnO_(2)基正极材料的基本问题和对应原因,探讨了最近研究中的优化策略。最后,基于MnO_(2)在不同储能机制中存在的问题,结合最新研究进展,提出了一系列推动Zn//MnO_(2)电池商业化的关键性挑战,对AZIBs未来的研究趋势进行了展望。To date,many remarkable breakthroughs have been achieved for the cathode materials of aqueous zinc-ion batteries(AZIBs),but many problems,such as poor structural stability,easy dissolution,serious electrostatic interaction between the material skeleton and poor electrical conductivity,still need to be solved.Therefore,further research and key technical support are in urgent need.The energy storage mechanism of MnO_(2) as cathode material for AZiBs is more complicated than other materials and has been controversial,which is the main factor limiting the application prospect of Zn//MnO_(2) batteries.Herein,the characteristics and energy storage mechanisms of the latest MnO_(2)-based cathode materials were summarized.The basic problems and corresponding deep-rooted causes of MnO_(2)-based cathode materials were reviewed,with the optimization strategies in recent research discussed.Finally,based on the existing problems in different energy storage mechanisms of MnO_(2) as well as the latest research progress,a series of key challenges in promoting the commercialization of Zn//MnO_(2) batteries were put forward,and the future research trends of AZIBs were prospected.
