Facile synthesis of Mn2SnO4@C composite from sugarcane bagasse as an anode material for lithium-ion batteries

This study presents the facile synthesis of a high-performance anode material for lithium-ion batteries (LIBs), based on a composite of Mn2SnO4 and carbon derived from sugarcane bagasse (SCB), denoted as Mn2SnO4@C. The synthesis involved the impregnation followed by pyrolysis at 600oC for 2 hours, which not only utilized sugarcane bagasse as a cost-effective carbon source but also enabled in situ incorporation of Mn2SnO4 into a carbon matrix, using MnCl2/SnCl2 salt mixtures as the precursors. The composite demonstrates a unique structure associated with the transition of metal oxides during lithiation/delithiation cycles. Electrochemical evaluations reveal that the Mn2SnO4@C composite exhibits excellent lithium storage performanceincluding a high speciMic capacity and good cycling stability described by the high capacity of 1002 mAh g-1 at the Mirst discharge cycle and the discharge capacity of 541 mA g-1 obtained during Minal cycles of 80 cycles process. Additionally, coulombic efMiciency reached over 95% after the Mirst three cyclesand achieved 100% thereafter. These results draw an attention to the potential of the Mn2SnO4@C composite as a promising anode material for next-generation LIBs. Furthermore, this work highlights the feasibility of utilizing agricultural biomass as the eco-friendly and cost-effective product for advanced energy storage systems.
