Abstract

Abstract : Antimony and red phosphorus (RP) hybrid is harvested via a facile mechanical milling strategy. Simultaneously, graphene sheets are introduced to boost the electronic transmission and mitigate the agglomeration of particles. In contrast to pristine Sb and RP electrodes, Sb/P/C hybrid affords comparably promising electrochemical performances. As anodes for lithium‐ion batteries, Sb/P/C electrode depicts a reversible capacity of 869 mAh g −1 under 200 mA g −1 after 50 cycles and an excellent rate stability such as 452 mAh g −1 at 3200 mA g −1 . When used for sodium‐ion batteries, the hybrid also shows moderate capacities of 544.8 and 511 mAh g −1 at the current of 50 and 200 mA g −1 after 50 cycles, respectively. These excellent properties can be ascribed to the synergetic effect of decreased particle size of milled Sb/P/C, large contact area, adequate energy storage sites, and enhanced electrical conductivity. Abstract : In this work, a graphene‐doped Sb/P/C electrode is synthesized by a simple ball milling method, which shows a good cycling performance and enhanced Li/Na storage capability.
