In situ-formed LiVOPO4@V2O5 core-shell nanospheres as a cathode material for lithium-ion cells

The nanospheres are synthesized via hydrothermal route followed by surface oxidation treatment and composed of an orthorhombic LiVOPO4 core with a tetragonal V2O5 shell. It delivers a special charge/discharge mechanism and has remarkably high-rate capability and long cycle ability, which indicates their potential application as a cathode material in advanced lithium-ion batteries.149
