Abstract
An electrode comprising: NaVOPOhaving orthorhombic crystalline symmetry and space group Pna2, as an active intercalation host material, wherein the electrode is capable of electrochemical insertion and release of greater than one sodium ion per vanadium, wherein the NaVOPOis formed by a solid phase synthesis process from a heated powdered mixture of ammonium metavanadate, ammonium phosphate monobasic, and potassium carbonate, to yield KVOPOhaving corner-sharing VOoctahedra and POtetrahedra, defining two types of tunnels comprising a first type of tunnel formed of rings of two POtetrahedra and a second type of tunnel formed of rings of three POtetrahedra and three VOoctahedra, followed by substitution of the potassium ions with sodium ions.
