報(bào)告摘要：Antimony (Sb) emerges as an attractive anode material for both lithium, sodium and potassium ion batteries (LIB, SIB, KIB) due to its high theoretical capacity of 660 mA h g-1. We designed and fabricated a novel peapod-like N-doped carbon nanotube encapsulated Sb nanorod composite，Sb@N-C, via a bottom-up confinement approach. The N-doped-carbon coating and thermal-reduction process was monitored by in-situ high-temperature X-ray diffraction characterization. Then, we employed Sb@N-C as an anode for LIB, SIB and KIB, Sb@N-C displayed the best long-term cycle performance among the reported Sb-based anode materials and impressive rate capability up to 20 A g-1. Especially in the case of KIB, the introduction of KFSI electrolyte salt functions as an effective strategy for greatly boosting electrochemical performance. We also identified the potassiation of Sb anode is quite reversible and undergoes multistep processes, combining solid solution reaction and two-phase reaction.
