Optimized Proton Assistance of Ni‐Intercalated Bilayer Vanadate Cathode for High‐Performance Aqueous Manganese Storage

ions effectively alleviates the limitations of high charge density and large solvation ion radius. Furthermore, the storage mechanism and structural evolution process are investigated via analytical chemistry. These findings provide new ideas for designing new positive electrode materials and effectively promote the progress of the MIB research and application.
