▎ 摘　　要

NOVELTY - Improvement of electrochemical property of lithium-iron phosphate involves performing chemical reduction of graphite oxide and aniline, carrying out electroless self-polymerization process, processing the resultant material using treatment liquid having electroconductivity and corrosion resistance and forming graphene/polyaniline composite layer on a surface of lithium-iron phosphate powder. During the electroless self-polymerization process, the graphite oxide is reduced to graphene, and aniline is oxidized to polyaniline. USE - Improvement of electrochemical property of lithium-iron phosphate used in battery (claimed) e.g. lithium battery. ADVANTAGE - The method economically improves electrochemical property of lithium-iron phosphate, without usage of organic solvent, surfactant, reducing agent and oxidizing agent. The battery obtained using the lithium-iron phosphate has excellent cycle stability and rate characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for battery.
