AbstractTransition metal oxides have wide potential applications in high‐performance energy‐storage devices. Herein, hierarchically rambutan‐like Zn3V3O8 (ZVO) hollow spheres are fabricated using a simple reflux/anneal strategy. These hollow spheres are enriched with highly porous features and a favorable surface area, which can afford abundant Li+/K+ transport paths, mitigate the volume dilatation, and boost the ion‐storage capabilities. As the anodes for lithium‐ion batteries, the ZVO electrodes can sustain a high discharge capacity of 1283.7 at 0.2 A g−1 after 50 cycles. Even as the current density reaches 5 A g−1, the reversible discharge capacity also remains 541 mA h g−1 after 1000 long‐term cycles. As the anodes for potassium‐ion batteries, ZVO electrodes can afford a discharge specific capacity of 100.1 mA h g−1 at 0.1 A g−1 after 100 cycles. The results demonstrate that hierarchically rambutan‐like ZVO hollow spheres can serve as a feasible candidate for Li+/K+ storage.
