Abstract

Abstract : Bi2 S3 /graphene aerogels as high rate performance anode material for sodium ion batteries. Abstract : A hierarchically structured Bi2 S3 /graphene aerogel composite is constructed that shows excellent sodium storage properties. Specifically, the composite delivers a stable reversible capacity of 397 mA h g −1 at 100 mA g −1 after 50 cycles and 348 mA h g −1 at 1 A g −1 after 120 cycles. Furthermore, even at a high current density of 2 A g −1, a reversible capacity of 336 mA h g −1 is achieved.
