▎ 摘　　要

NOVELTY - Graphene composition comprises thiourea in which the element ratio of sulfur to carbon measured in X-ray photoelectron spectroscopy measurement is 0.04-0.12. USE - The graphene composition is useful in an electrode for a lithium ion battery (claimed). ADVANTAGE - The graphene composition: is highly dispersible and highly conductive; and provides lithium ion battery electrode with high capacity, high output and good cycle characteristics or excellent discharge performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an electrode for a lithium ion battery, comprising the graphene composition, an electrode active material and a binder; and (2) producing the graphene composition, comprising reducing a graphite oxide at 20-60 degrees C in the presence of thiourea.
