Silicon nanoparticles-graphene paper composites for Li ion battery anodes.
Composites of Si nanoparticles highly dispersed between graphene sheets, and supported by a 3-D network of graphite formed by reconstituting regions of graphene stacks exhibit high Li ion storage capacities and cycling stability. An electrode was prepared with a storage capacity >2200 mA h g(-1) after 50 cycles and >1500 mA h g(-1) after 200 cycles that decreased by <0.5% per cycle.
