Facile and scalable synthesis of nanostructured Fe2O3 using ionic liquid-assisted ball milling for high-performance pseudocapacitors

Ionic liquid-assisted ball milling of iron precursors in the absence of any reagent produced the scalable production of crystalline Fe2O3 with a favourable morphology for supercapacitor applications, showing high specific capacitance, high rate capability, and excellent cycle life.280
