Enabling multi-electron reaction of ϵ-VOPO4 to reach theoretical capacity for lithium-ion batteries

By controlling the morphology and particle size of the epsilon polymorph of vanadyl phosphate, ϵ-VOPO4, it can fully reversibly intercalate two Li-ions and reach the theoretical capacity of 305 mA h g−1 over two voltage plateaus at about 4.0 and 2.5 V.
