Patent ID: 8022009

Claim:
A method of producing a Li w M 1 x M 2 y ZO 4 /carbon composite material comprising: (a1) reacting at least one M 1 precursor with at least one ZO 4 precursor in an aqueous based solvent, wherein the at least one M 1 precursor has an oxidation state <1, wherein Z is selected from the group consisting of P, Si, S, Al, Ge, N, and V; (a2) adding an accelerator to the aqueous based solvent; (b) drying the reaction; (c) mixing the dried reaction with a lithium precursor; (d) adding one or both a dopant and a carbon precursor to the mixture, wherein the dopant is at least a M 2 precursor, wherein M 2 is a metal element; and (e) calcining the doped mixture.
