In this work, a novel strategy to fabricate ternary MoS2/SiO2/graphene hybrids (MSGs) was developed by incorporating amorphous SiO2 with MoS2 and graphene nanosheets. Serving as anode material in lithium ion batteries, the inert silica component can effectively prevent the pulverization caused by the inner-plane volume expansion of MoS2. It turns out that MSGs with similar to 40 wt% of SiO2 and similar to 42 wt% of MoS2 manifest the capacity stabilized at 1060 mAh g(-1) for more than 100 cycles at the current density of 0.1 A g(-1). Further, this MSG electrode maintains the specific capacity of 580 mAh g(-1) at an ultrahigh current density of 8 Ag-1, which outperforms those of the reported MoS2 and MoS2/graphene hybrids.
