摘　　要：可充电水系锌离子电池由于低成本和高安全性,被认为是储能设备的理想候选者。近年来,锰基正极材料由于低成本、低毒性、高工作电压、价态丰富和晶体结构多变等特点,得到广泛研究。锰基材料在循环过程中因结构坍塌引起的容量衰减,阻碍了水系锌离子电池的进一步发展。综述锰基正极材料的研究进展,包括各种锰基氧化物(MnO_(2)、Mn_(2)O_(3)、Mn_(3)O_(4)和MnO等)及其储锌机理。归纳提高锰基正极材料电化学性能的优化策略,并展望锰基正极材料未来的发展。Rechargeable aqueous zinc-ion battery is considered to be ideal candidates for energy storage devices due to their low cost and high safety.In recent years,manganese-based materials have been widely investigated because of their low cost,low toxicity,high operating voltage,multi-valence states and various crystal structures.The capacity decay caused by structural collapse during cycling has hindered the further development of manganese-based cathodes.The research progress in manganese-based cathode materials,including various manganese-based oxides(MnO_(2),Mn_(2)O_(3),Mn_(3)O_(4) and MnO)and their zinc storage mechanisms is reviewed.The optimization strategies for improving the electrochemical performance of manganese-based cathode materials are summarized,the future development of manganese-based cathode materials is prospected.
