▎ 摘 要
A hierarchically structured Bi2S3/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.
