▎ 摘　　要

NOVELTY - Preparing lithium iron phosphate microspheres/graphene composite electrode material involves mixing iron phosphate and carbohydrate polyhydroxy compounds taken in mass ratio of 1:0.1-02 and heating hydrothermally at 100-150 degrees C hydrothermal reaction. The product is washed and dried to obtain spherical iron source. The iron source is mixed with lithium source and graphene oxide in mass ratio of 1:0.1-0.5, in an inert atmosphere and reacts thermally at high temperature to form lithium iron microspheres/graphene composite electrode material. USE - Lithium iron microspheres/graphene composite electrode material is use for making lithium battery (claimed). ADVANTAGE - The lithium iron microspheres/graphene composite electrode material has high electronic conductivity, high ionic conductivity, high tap density, high power rate density and energy density.
