Strongly coupled tungsten oxide/carbide heterogeneous hybrid for ultrastable aqueous rocking‐chair zinc-ion batteries

[Display omitted] •WO3/WC hybrid is designed and synthesized by facile annealing method.•WO3/WC hybrid with low Zn2+ intercalated potential is demonstrated.•The strong interaction and electronic coupling between WO3 and WC are determined.•Significant rate and cycling stability can be achieved for WO3/WC hybrid.•The WO3/WC||MnO2/graphite rocking‐chair ZIBs achieve excellent performance. Aqueous Zinc-ion batteries (ZIBs) are recognized as the most pivotal competitor of lithium-ion batteries due to their abundant reserves, remarkable safety and affordable cost. However, the uncontrollable dendritic growth and extremely low utilization (
