Abstract
The Graphite/Silicon@reGO composite was synthesized via spray drying and subsequent annealing. According to XRD, Raman spectroscopy and FT-IR, graphene was demonstrated to be existed in the composite. Moreover, SEM and TEM were also used to illustrate the morphology of Graphite/Silicon@reGO. Used as anode for lithium-ion battery, it exhibited good cyclability with a high reversible charge capacity of 575.1 mAh gâ1 and showed a capacity retention ratio of 73.1% after 50 cycles at a current density of 50 mA gâ1. It also presented good rate capability at different rates of 50-1000 mA gâ1. EIS test showed that the composite electrode had a lower SEI resistance and charge-transfer resistance due to the existence of graphene.
