Abstract:
The present invention reports the development of electrochromic supercapacitor application that comprises the vanadium doped cobalt chloride carbonate hydroxide. And, more particularly, developing a process to synthesize for use as electrochromic supercapacitor application. Methods of preparing the material and use for electrochromic supercapacitor application of the invention are also described. The catalyst shows a high capacitance value of the electrochromic supercapacitor having a capacitance value of 1219F/g in alkaline medium with an optical modulation (∆T) value of 69% coloration efficiency value of 65 cm2c-1 at a wavelength of 600 nm. This invention provides a new vision for developing materials with dual characters, i.e., storing energy and changing its color for promising electrochromic supercapacitor applications.
