α-Fe2O3/rGO nanospindles as electrode materials for supercapacitors with long cycle life

Spindle-like α-Fe2O3 and reduced graphene (rGO) composites have been synthesized by a simple hydrothermal method. The synthesized samples exhibit excellent electrochemical performance with high specific capacitance and good cycling life. [Display omitted] •Spindle-like α-Fe2O3 and reduced graphene (...
