GRAPHENE DISPERSION LIQUID, METHOD FOR PRODUCING SAME, AND ELECTRODE FOR SECONDARY BATTERY

A graphene dispersion liquid containing graphene dispersed in a dispersion medium is described, in which, in the graphene contained in the dispersion liquid, a proportion of graphene with a size in the plane direction of 500 nm or more and 1 μm or less is 30% or more on an area basis, and a proportion of graphene with a size in the plane direction of 10 μm or more and 50 μm or less is 30% or more on an area basis. The graphene dispersion liquid is in a stable dispersion state and forms a strong conductive path.
