Carbon Superstructure‐Supported Half‐Metallic V2O3 Nanospheres for High‐Efficiency Photorechargeable Zinc Ion Batteries

Photorechargeable zinc ion batteries (PZIBs), which can directly harvest and store solar energy, are promising technologies for the development of a renewable energy society. However, the incompatibility requirement between narrow band gap and wide coverage has raised severe challenges for high-efficiency dual-functional photocathodes. Herein, half-metallic vanadium (III) oxide (V
