摘　　要：锌离子电池(ZIBs)由于其安全性、可持续性、成本效益和高能量密度而越来越受欢迎,有望成为锂离子电池(LIBs)的替代品。目前对锌离子电池已经进行了广泛的研究。然而,锰基正极材料在锌离子电池中的应用带来了挑战,特别是金属溶解和材料不稳定性等问题。这些挑战导致电池循环稳定性较差,阻碍了锌离子电池发展的进程。本文概述了锌离子存储机制,阐明了锰基正极材料面临的挑战,并提出了改善其性能的优化策略。最后,讨论了锰基正极材料的潜力。Non-renewable energy sources such as fossil fuels are increasingly depleted.In order to cope with the potential energy crisis,it is urgent to develop clean and efficient renewable energy sources.Advanced energy storage technology based on electrical energy holds critical significance to the sustainable and steady development of human society.Aqueous rechargeable batteries are a kind of promising electrochemical energy storage devices.Zinc-ion batteries(ZIBs)are gaining increasing popularity due to their safety,sustainability,cost-effectiveness and high energy density,positioning them as potential successors to current Lithium-ion batteries(LIBs)with a high degree of commercialization.The extraordinary mechanical flexibility and excellent electrochemical performance exhibited by ZIBs holds great significance in advancing the development of flexible and wearable batteries.Manganese-based oxides with large channel size possess the characteristics of high theoretical capacity,various oxidation states(including+2,+3,+4)and low cost,which are commonly employed as cathode materials for AZIBs.Nevertheless,the electrochemical performance of current manganese-based ZIBs is not satisfactory,facing the challenges of metal dissolution,material structure instability,notably a strong electrostatic interaction exhibited by divalent Zn2+ions in the host structure resulting in slow transmission kinetics.These challenges contribute to low cycle stability of the battery,impeding practical application and the progression of ZIBs.To solve these problems,diverse structural engineering strategies including defect engineering have been exploited,which can effectively improve the transport kinetics of zinc ions.From the perspective of enhancing the performance of the material itself,interlayer intercalation and other measures can be taken to better the microstructure or morphology of manganese-based materials.By improving the electrical conductivity of the material and enhancing ionic bonding,the structural stability and electrochemical p
