摘要：
The invention relates to a process for coating nanoparticles with graphene, comprising the steps of (a) providing a suspension comprising a suspension medium and nanoparticles with positive surface charge, (b) adding graphene oxide particles to the suspension from step (a), the graphene oxide particles accumulating on the nanoparticles, and (c) converting the graphene oxide particles accumulated on the nanoparticles to graphene, to graphene-coated nanoparticles comprising at least one metal, a semimetal, a metal compound and/or a semimetal compound, and to the use of these graphene-coated nanoparticles in electrochemical cells and supercapacitors, and to supercapacitors and electrochemical cells comprising these nanoparticles.
