▎ 摘　　要

NOVELTY - A carbon-coated lithium-iron phosphate ternary composite is obtained by ball-milling and homogenizing water-soluble organic small molecules, high-molecular polymer, and graphene compound with an iron source compound, a phosphorus source compound, and a lithium source compound, drying, and sintering the obtained composite precursor. USE - Carbon-coated lithium-iron phosphate ternary composite is useful as anode active material in lithium ion batteries (claimed). ADVANTAGE - The carbon-coated lithium-iron phosphate ternary composite has improved conductivity, tap density, residual carbon reduction activity, and lithium-ion diffusion coefficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of carbon-coated lithium-iron phosphate ternary composite.
