ABSTRACT

Disclosed is a method for producing colloidal graphene dispersions comprising the steps of (i) dispersing graphite oxide in a dispersion medium to form a colloidal graphene oxide or multi-graphene oxide dispersion (ii) thermally reducing the graphene oxide or multi-graphene oxide in dispersion.Dependent on the method used for the preparation of the starting dispersion a graphene or a multi-graphene dispersion is obtained that can be further processed to multi-graphene with larger inter-planar distances than graphite. Such dispersions and multi-graphenes are for example suitable materials in the manufacturing of rechargeable lithium ion batteries. More... »
