dc.description.abstract | Tin phosphide (Sn4P3) has emerged as an anode for sodium ion batteries (SIBs) due to its high reversible capacity and low redox potential. Sn4P3 shows a synergistic Na-storage reaction to form Na15Sn4 and Na3P, but suffers from large volume expansion and Sn aggregation during the Na+ insertion-extraction resulting in poor cycle stability. Sn4P3 has also been considered a promising anode material for lithium ion batteries (LIBs), but very limited studies have been performed. Herein, core-shell Sn4P3-C (carbon) composite nanospheres are fabricated by carbonization/reduction and phosphorization of SnO2-GCP (glucose-derived, carbon-rich polysaccharide) nanospheres. The size of Sn4P3-C nanospheres is controlled to optimize their electrochemical performance as long-term stable anodes for SIBs and LIBs. Among them, the 140 nm-sized Sn4P3-C nanosphere electrode exhibits high reversible capacity, high rate capability, and ultra-long cycle stability as an anode for both SIBs and LIBs, delivering a high capacity of 420 mA h g(-1) after 2000 cycles (SIBs) and 440 mA h g(-1) after 500 cycles (LIBs) at a high current density of 2000 mA g(-1). Hence, the Sn4P3-C nanospheres can be considered as a promising anode material for next generation SIBs and LIBs. | - |
