▎ 摘　　要

NOVELTY - Preparing high specific surface area reduction oxidation graphene/carbon tube composite powder comprises (i) attaching carbon nano-tube by sodium bicarbonate, interlayer insertion in graphene dispersion liquid to obtain composite powder, and (ii) reducing and peeling the composite powder by heat treatment to obtain high specific area of reduced oxidized graphene/carbon tube composite powder. USE - The preparation method for high specific surface area reduction oxidation graphene/carbon tube composite powder is useful in lithium battery (claimed). ADVANTAGE - The method has excellent conductivity.
