“…25,26 Meanwhile, manganese vanadate also exhibits promising electrochemical behaviors, which originate from its layered structure, relatively low molecular weight, and the polyvalent properties of manganese. [27][28][29][30] Nevertheless, similar to other transition metal oxides, manganese vanadate suffers from some disadvantages such as poor conductivity for electron transfer and ion diffusion, and severe volume changes during the charging and discharging process, leading to crushing of the electrode material and thus a suboptimal rate performance and cycling stability. To address these issues, many strategies have been used to overcome these drawbacks, such as nanohybrids, 6,10,12,31 surface-coating, 5,11,32 interfacial engineering, 33 and element-doping.…”
