▎ 摘 要
NOVELTY - A graphene oxide derivative lithium salt preparation method involves taking graphite powder, preparing graphite oxide by a chemical oxidation process, and carrying out ultrasonic dispersion to obtain the graphene oxide. Heat treatment is carried out on the graphene oxide at 100-800 degrees C in a protective gas atmosphere for 10 minutes to 10 hours to obtain graphene. The graphene subjected to heat treatment is mixed with a lithium salt, stirred to react, and dried to obtain the graphene oxide derivative lithium salt material. USE - Method for preparing a graphene oxide derivative lithium salt that is utilized for an anode material of a lithium ion battery (claimed). ADVANTAGE - The method enables preparing the graphene oxide derivative lithium salt in a simple manner and in a short period of time, and improving the conductivity, mechanical property, power intensity and capacity of the battery.
