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.
