▎ 摘 要
NOVELTY - A graphene oxide has carbon-oxygen ratio of 2.5-4, measured by X-ray photoelectron spectroscopic analysis. USE - Graphene oxide is used for positive electrode for lithium-ion secondary battery. Uses include but are not limited to mobile telephone, smart phone, electronic book, handheld game machine, hybrid vehicle, tape recorder, helicopter, aircraft, rocket, satellite, etc. ADVANTAGE - The graphene oxide has excellent dispersibility, electroconductivity, mechanical property and chemical property.
