alpha-Fe2O3 thin film on stainless steel mesh: A flexible electrode for supercapacitor
Light and flexible energy storage devices have taken great attention from the industrial point of view. We report the deposition of alpha-Fe(2)O(3)on thin, light weight and flexible stainless steel mesh substrate. Liquid phase deposition (LPD) which is simple, inexpensive and additive/binder free method is used for deposition. Supercapacitive performance of alpha-Fe(2)O(3)thin films deposited on stainless steel mesh are studied in 0.5 M Na2SO3 electrolyte. The highest specific capacitance obtained is 960 F g(-1) at 4 mA cm(-2) from charge-discharge curves. The supercapacitive performance is significantly improved when alpha-Fe2O3 thin films are deposited on mesh substrate as compared to flat substrate.
