Document Type and Number:
Japanese Patent JP6939931
Kind Code:
B2
Abstract:
The present invention relates to preparation of a highly dispersible graphene powder. Further, an object of the present invention is to provide an electrode for a lithium ion battery having good output characteristics and cycle characteristics by utilizing a highly dispersible graphene powder. The present invention provides a graphene powder having a specific surface area of 80 m 2 /g or more to 250 m 2 /g or less as measured by BET measurement, and an oxygen-to-carbon element ratio of 0.09 or more to 0.30 or less as measured by X-ray photoelectron spectroscopy.
