Claim 12:
13. A method of forming an NaVOPO4 electrode, comprising a VOPO4 lattice,
the VOPO4 lattice having a volume greater than 90 Å3 per VOPO4; and
a portion of the VOPO4 lattice having two sodium ions per VOPO4,
the method comprising:
forming a mixture of ammonium metavanadate, ammonium phosphate monobasic, and potassium carbonate;
synthesizing KVOPO4 in a solid phase by heating the mixture;
combining the KVOPO4 with conductive particles to form a conductive mixture; and
replacing at least a portion of potassium ions with sodium ions to form a NaVOPO4.
