Highly dispersible graphene composition, preparation method thereof, and electrode for lithium ion secondary battery containing highly dispersible graphene composition

摘要

In order to prepare highly conductive and highly dispersible graphene and obtain an electrode for a lithium ion battery with good output characteristics and cycle characteristics, there is provided a graphene composition containing thiourea, the element ratio of sulfur to carbon being 0.04 or more and 0.12 or less in X-ray photoelectron spectroscopy measurement.
