Supercapacitor electrode, useful in supercapacitor, comprises mixture of graphene sheets comprising pristine graphene material or non-pristine graphene material, and humic acid.

CHAI S, ZHAMU A, JANG B Z

Production of isolated graphene sheets from supply of coke or coal powder for e.g. graphene-containing ink composition involves exposing supply of coke or coal powder to supercritical fluid and rapidly depressurizing supercritical fluid.

ZHAMU A, JANG B Z

Production process for graphene-based supercapacitor electrode, involves rapidly depressurizing supercritical fluid at set fluid release rate to effect exfoliation and separation of coke or coal powder to produce isolated graphene sheets.

ZHAMU A, JANG B Z

Producing isolated graphene sheets from supply of coke or coal powder, used in composite material, comprises dispersing particles of coke or coal powder in liquid medium to produce suspension, and exposing suspension to ultrasonication.

ZHAMU A, JANG B Z

Production of isolated graphene sheet for e.g. composite material, involves forming intercalated coke or coal compound using petroleum coke by electrochemical intercalation, and exfoliating and separating hexagonal carbon atomic interlayers.

ZHAMU A, JANG B Z

Production of isolated graphene sheets involves forming intercalated graphite compound in intercalation reactor comprising liquid solution electrolyte, working and counter electrode, and exfoliating hexagonal carbon atomic interlayers.
