Abstract
A freestanding 3D network strucutre of graphene/Si/graphene designed & fabricated.
Coloumbic efficiency of the first de-/liathiation cycle over 80%.
Stable areal capacities up to 0.62 mAh cm-2 were achieved.
Anodes maitained interconnected, superlight, flexible structures after 1000 cycles.
