Abstract: A lithium battery with an improved cathode. The cathode comprises the epsilon polymorph of vanadyl phosphate, ε-VOPO4, made from solvothermally synthesized H2VOPO4, and optimized to reversibly intercalate two Li-ions to reach full theoretical capacity with a coulombic efficiency of 98%. This material adopts a stable 3D tunnel structure and can extract two Li-ions per vanadium ion, giving a theoretical capacity of 305 mAh/g, with an upper charge/discharge plateau at around 4.0 V, and one lower at around 2.5 V The ε-VOPO4 particles may be modified with niobium (Nb) to improve the cycling stability.
