▎ 摘  要

NOVELTY - Preparing cobalt-niobium-oxide (CoNb2O6) composite porous graphene composite material comprises obtaining a graphene oxide dispersion, adding 30% hydrogen peroxide solution into the graphene oxide dispersion, heating to 75-95°C for reaction, adding cobalt oxide and niobium oxide in the reacted product, ball milling at 700-900°C under a protective gas atmosphere and reacting at a constant temperature. USE - The composite material is useful in lithium ion battery cathode material. ADVANTAGE - The composite material has good conductivity, high capacity and good cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene composite material prepared by the above method. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the method for preparing the cobalt-niobium-oxide (CoNb2O6) composite porous graphene composite material (Drawing includes non-English language text).
