Multilayer Graphene

Flexible ‘graphene paper’ electrodes displayed poor electrochemical performance compared to powder composed of reduced graphene oxide platelets, in spite of the good conductivity and mechanical stability of such paper samples. [168] However, when silicon nanoparticles were mixed with reduced graphene oxide platelets in a paper-like material, a storage capacity > 2200 mAhg − 1 after 50 cycles and > 1500 mAhg − 1 after 200 cycles was obtained recently. [169] It was stated that the uniform dispersion of silicon particles in the composites and the reconstitution of graphene platelets to from a continuous, highly conducting 3D network are important for the high storage capacities.
