摘要：

Sodium insertion in three vanadium oxides is studied with regard to their use as cathode materials in solid-state sodium batteries. One channel structure (β-NaxV2O5) and two layered structures (Na1+xV3O8 and α-V2O5) are investigated. The stoichiometric energy densities calculated from the first discharges were 245, 340, and 430 Wh/kg, respectively. Both Na1+xV3O8 and β-NaxV2O5 degraded gradually during cycling. The structure of α-V2O5 changes after the first discharge, but the new phase exhibits excellent capacity retention upon cycling.
