GRAPHENE/ORGANIC SOLVENT DISPERSION AND METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING LITHIUM-ION BATTERY ELECTRODE

A graphene/organic solvent dispersion liquid is in a stably dispersed state and also unlikely to cause electrolysis of water. A graphene/organic solvent dispersion liquid is also provided including graphene dispersed in an organic solvent and having a value of (W2−W1)/G in the range of 0.005 or more...

Beschreibung
Zusammenfassung:	A graphene/organic solvent dispersion liquid is in a stably dispersed state and also unlikely to cause electrolysis of water. A graphene/organic solvent dispersion liquid is also provided including graphene dispersed in an organic solvent and having a value of (W2−W1)/G in the range of 0.005 or more and 0.05 or less, wherein W1 and W2 are the water fractions measured at 130° C. and 250° C., respectively, by the Karl Fischer's method and G is the solid fraction of the graphene.
