▎ 摘　　要

NOVELTY - A lithium/graphene composite material consists of three layers of lithium iron phosphate/graphene composite material. USE - Lithium/graphene composite material used as lithium ion battery material (claimed). ADVANTAGE - The lithium/graphene composite material is manufactured economically by a simple process, with improved productivity. The batteries produced have high specific capacity and excellent charging/discharging performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the lithium/graphene composite material, which involves mixing dihydrogen phosphate ions (0.015-2.0 mol/l), ferrous ions (0.01-2.0 mol/l) and lithium ion solution (0.01-2.0 mol/l) with organic amine used as template agent to obtain a suspension, filtering and vacuum drying the suspension to obtain a powder, grinding the powder, heating the powder in inert atmosphere at 500-900 degrees C for 4-6 hours, cooling to room temperature to obtain lithium/graphene composite material as black powder.
