Ge–graphene–carbon nanotube composite anode for high performance lithium-ion batteries

Abstract

A Ge–graphene–carbon nanotube composite electrode has been successfully synthesized and evaluated. The composite exhibits high rate capability and cycle stability, which is ascribed to the graphene sheet that improves electric conductivity and the CNT mechanically binds together with Ge–RGO to maintain the integrity of the electrodes and stabilize the electric conductive network for the active Ge nanoparticles.
