Self-Standing Co2.4sn0.6o4 Nano Rods as High Performance Anode Materials for Sodium-Ion Battery and Investigation on its Reaction Mechanism
The self-standing nanorod Co 2.4 Sn 0.6 O 4 is synthesized as a high-performance anode material in search of high capacity and stable anode materials for sodium-ion batteries. The Co 2.4 Sn 0.6 O 4 nanorod exhibits a high reversible capacity of 576 mAh g -1 at a current density of 80 mA g -1 and shows excellent high-rate capability. The X-ray absorption spectroscopy study reveals the mechanisms of charge storage reaction and improved cycling performance of Co 2.4 Sn 0.6 O 4 . A partially limited conversion reaction of Co- and Sn-oxide during the cycling effectively regulate the irreversible capacity loss over the cycling that is commonly observed from the conversion and alloying reaction-based anode materials. Furthermore, Co 2.4 Sn 0.6 O 4 also exhibits superior sodium-ion full cell performance when coupled with a NaNi 2/3 Bi 1/3 O 2 cathode, demonstrating an energy density of 262 Wh kg -1
