Synthesis of Sb2S3 NRs@rGO Composite as High-Performance Anode Material for Sodium-Ion Batteries

Abstract

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 Sb2S3 nanorods (Sb2S3 NRs) on reduced graphene oxide (Sb2S3 NRs @rGO) as anode materials for SIBs. Based on this work, Sb2S3 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, Sb2S3 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 Sb2S3 NRs and Sb2S3 NRs@rGO for SIBs.

“…Considering large surface area and high electrical conductivity, a typical structural stabilizer (RGO) has been widely explored in sodium-storage systems. , For instance, using graphene sheets as a loading matrix, Sb 2 S 3 NRs@rGO anodes were successfully prepared, exhibiting a capacity of 769.05 mAh g –1 at 0.1 A g –1 . Even at 0.5 A g –1 , the capacity could reach up to 614.5 mAh g –1 after 300 cycles . Moreover, conductive polymers, as a type of organic with optimized polysulfide-capturing capability, have been introduced in Sb 2 S 3 with the obvious enhancement of capacity.…”
