ϵ-VOPO4 cathode for lithium ion batteries
Abstract
The epsilon polymorph of vanadyl phosphate, ε-VOPO4, made from the solvothermally synthesized H2VOPO4, is a high density cathode material for lithium-ion batteries optimized to reversibly intercalate two Li-ions to reach the full theoretical capacity at least 50 cycles 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.
