Alloying-type anode materials are regarded as promising alternatives beyond intercalation-type carbonaceous for sodium storage owing to the high specific capacities. The rapid capacity decay arising from huge volume change during Na+-ion insertion/extraction, however, impedes practical application. Herein, we report an ultrafine antimony embedded in a porous carbon nanocomposite (Sb@PC) synthesized via facile situ substitution of Cu nanoparticles metal–organic framework (MOF)-derived octahedron storage. Sb@PC composite displays appropriate redox potential (0.5–0.8 V vs Na/Na+) and excellent capacities 634.6, 474.5, 451.9 mAh g–1 at 0.1, 0.2, 0.5 A after 200, 500, 250 cycles, respectively. Such superior performance is primarily ascribed MOF-derived three-dimensional Sb nanoparticles, which not only provides penetrating network transfer charge carriers but also alleviates agglomeration expansion cycling. Ex X-ray diffraction Raman analysis clearly reveal five-stage reaction mechanism sodiation desodiation demonstrate reversibility Furthermore, post-mortem reveals that robust structural integrity can withstand continuous insertion/extraction. This work may provide insight into effective design high-capacity alloying-type advanced secondary batteries.
