Abstract
Sb/acetylene black (Sb/AB) composite was firstly applied as anode for sodium-ion batteries (SIBs). A great electrochemical performance of the composite was obtained when utilizing this composite for SIBs. It was found that the charge capacity can reach 473 mAh gâ1 in the 70th cycle at a current density of 100 mA gâ1, and we also note that the capacity contributed by Sb was about 624 mAh gâ1, which is very close to its theoretical sodium storage capacity (660 mAh gâ1 corresponding to a formula of Na3Sb), demonstrating the full utilization of Sb. It is interesting to see that even at a high current density of 1600 mA gâ1, the capacity can still reach 281 mAh gâ1.
