However, the electrochemical activity of pure Bi ₂ S ₃ is greatly limited during the sodiation/desodiation process. The integration of Bi ₂ S ₃ with reduced graphene and a particular carbon is explored to acquire active composite anodes for sodium ion batteries (SIBs). This special carbon is based on trimesic acid (H ₃ BTC) as a carbon source, which effectively prevents the aggregation of Bi ₂ S ₃ particles in the synthesis process. Compared with other carbon sources, this type of carbon source is more likely to diffuse into the interior of the precursor hole. Hence, the Bi ₂ S ₃ /C indicates higher reversible capacities (368 and 314?mAh?g ^?1 after 100 cycles and 200 cycles at 100?mA?g ^?1 ) than bare Bi ₂ S ₃ or Bi ₂ S ₃ @RGO. Thus, Bi ₂ S ₃ /C is considered as a prospective electrode material for rechargeable batteries. </p> </section> </abstract> 收起
