摘要:Different from previously reported mechanical alloying route to synthesize SnxP3, novel Sn4P3/reduced graphene oxide (RGO) hybrids are synthesized for the first time through an in situ low-temperature solution-based phosphorization reaction route from Sn/RGO. Sn4P3 nanoparticles combining with advantages of high conductivity of Sn and high capacity of P are homogenously loaded on the RGO nanosheets, interconnecting to form 3D mesoporous architecture nanostructures. The Sn4P3/RGO hybrid architecture materials exhibit significantly improved electrochemical performance of high reversible capacity, high-rate capability, and excellent cycling performance as sodium ion batteries (SIBs) anode materials, showing an excellent reversible capacity of 656 mA h g(-1) at a current density of 100 mA g(-1) over 100 cycles, demonstrating a greatly enhanced rate capability of a reversible capacity of 391 mA h g(-1) even at a high current density of 2.0 A g(-1). Moreover, Sn4P3/RGO SIBs anodes exhibit a superior long cycling life, delivering a high capacity of 362 mA h g(-1) after 1500 cycles at a high current density of 1.0 A g(-1). The outstanding cycling performance and rate capability of these porous hierarchical Sn4P3/RGO hybrid anodes can be attributed to the advantage of porous structure, and the synergistic effect between Sn4P3 nanoparticles and RGO nanosheets.
