مستخلص:	Doping and coating techniques are key methods to address volume expansion and capacity reduction associated with metal oxide-based anodes in lithium-ion batteries. This research focuses on combining graphene with SnO2 and Fe2O3. The composite compounds of rGO-Fe2O3-SnO2 exhibited a spherical and fluffy structure, with granular compounds distributed either on the surface of graphene or between its lamellar layers. 0.4% rGO-Fe2O3-SnO2 demonstrated the most favorable cycling performance and rate capability, with an initial discharge specific capacity of 1439.63 mAh/g and remained relatively stable at approximately 512.28 mAh/g after 1000 cycles. The incorporation of graphene reduced contact resistance and charge transfer resistance, which effectively mitigated the volume expansion phenomenon and enhanced the electrochemical stability.
