This research developed a flower-like W/WO3 hybrid as a cathode for ZIBs, showing exceptional rate performance and cycling performance. Additionally, the reversible Zn2+ insertion/extraction mechanism in W/WO3 was demonstrated for the first time, along with the impressive flexibility and capabilities of the soft-packaged batteries.
Aqueous zinc-ion batteries (ZIBs) with exceptional safety and cost-effective features have captured researchers' attention, but the cathode materials available still need to be further explored. Herein, a flower-like W/WO3 hybrid is developed as a cathode of ZIBs. Impressively, the W/WO3-ZIBs exhibit extraordinary rate performance (158 mA h g(-1) under 0.1 A g(-1)) and remarkable cycling performance (96% over 1000 cycles). Additionally, an electrochemical mechanism based on reversible Zn2+ insertion/extraction in W/WO3 is firstly demonstrated, and the impressive flexibility and excellent capabilities of the soft-packaged batteries are also realized. Therefore, this research will pave a novel consideration of metal/metal oxide hybrids in designing cathodes of ZIBs with high electrochemical performance.
