▎ 摘　　要

NOVELTY - Preparation of carbon composite lithium iron phosphate anode material involves mixing lithium source, phosphorus source (A), ferrous salt (A), nano-carbon-coated ferrous phosphate and solvent (A), hydrothermally reacting to obtain carbon composite lithium iron phosphate precursor, and calcining the precursor in inert atmosphere or reducing atmosphere. USE - Preparation of carbon composite lithium iron phosphate anode material for lithium-ion battery (all claimed) used in vehicle. ADVANTAGE - The prepared carbon composite lithium iron phosphate anode material has high compaction density and excellent electrochemical property.
