Abstract

We report a novel rGO/CNT/Si shell-like anode by using the vacuum filtration method, for lithium-ion batteries. The high-capacity silicon nanoparticles (SiNPs) are enclosed by a scaffold consisting of the stacked rGO shells and the CNT frame. The scaffold provides enough space for volume expansion of the SiNPs during the process of lithium-ion intercalation. The solid electrolyte interface (SEI) film forms on the surface of rGO shells, which can prevent electrolysis from consuming the silicon continuously. The anode demonstrates to enjoy the high specific capacity of 2372.77 mAh/g in initial cycle, and the superior recyclability with 1438.31 mAh/g after 100 cycles in a half-cell electrochemical test.
