Abstract | Potassium-ion batteries (KIBs) are considered a favorable candidate for large-scale electric energy storage system applications owing to the abundance and low-cost of potassium resources. Herein, a series of three-dimensional pomegranate-like SbxBi1-x@C composites are fabricated by a modified Pechini sol-gel method. As an anode for KIBs, the Sb0.5Bi0.5@C composite exhibits the optimal performance (382 mA h g(-1) at 0.05 A g(-1)). More importantly, the synergistic effects in the binary alloy bring a promising long-term cycle life (83% capacity retention after 400 cycles) for Sb0.5Bi0.5@C. The ex situ X-ray diffraction results reveal the K storage mechanism of this material, which is Sb0.5Bi0.5 <-> KSb0.5Bi0.5 <-> K3Sb0.5Bi0.5 during discharge and charge processes. In addition, a full cell constructed by coupling Sb0.5Bi0.5@C with a Prussian blue cathode delivers outstanding electrochemical performance. |
