    摘要： A process for producing a lithium vanadium phosphate-carbon composite includes a first step that includes mixing a lithium source, a tetravalent or pentavalent vanadium compound, a phosphorus source, and a conductive carbon material source that produces carbon through pyrolysis, in an aqueous solvent to prepare a raw material mixture, a second step that includes heating the raw material mixture to effect a precipitation reaction to obtain a reaction mixture that includes a precipitate, a third step that includes subjecting the reaction mixture that includes the precipitate to wet grinding using a media mill to obtain a slurry that includes ground particles, a fourth step that includes spray-drying the slurry that includes the ground particles to obtain a reaction precursor, and a fifth step that includes calcining the reaction precursor at 600 to 1300° C. in an inert gas atmosphere or a reducing atmosphere. A lithium vanadium phosphate-carbon composite produced by the process may provide a lithium secondary battery with excellent battery performance (e.g., high discharge capacity) when used as a cathode active material.
