Synthesis of Sb 2 S 3 NRs@rGO Composite as High-Performance Anode Material for Sodium-Ion Batteries.

Sodium ion batteries (SIBs) have drawn interest as a lithium ion battery (LIB) alternative owing to their low price and low deposits. To commercialize SIBs similar to how LIBs already have been, it is necessary to develop improved anode materials that have high stability and capacity to operate over many and long cycles. This paper reports the development of homogeneous Sb 2 S 3 nanorods (Sb 2 S 3 NRs) on reduced graphene oxide (Sb 2 S 3 NRs @rGO) as anode materials for SIBs. Based on this work, Sb 2 S 3 NRs show a discharge capacity of 564.42 mAh/g at 100 mA/g current density after 100 cycles. In developing a composite with reduced graphene oxide, Sb 2 S 3 NRs@rGO present better cycling performance with a discharge capacity of 769.05 mAh/g at the same condition. This achievement justifies the importance of developing Sb 2 S 3 NRs and Sb 2 S 3 NRs@rGO for SIBs.
