Plasticized lithium iodide-doped polyacrylonitrile-methylcellulose blend electrolytes for supercapacitor application

This paper reports the characterisation and application of plasticized polyacrylonitrile (PAN)-methylcellulose (MC) doped with lithium iodide (LiI) in a symmetric supercapacitor at ambient temperature. From Fourier transform infrared spectroscopy (FTIR) analysis, the shifting of hydroxyl (OH) band t...
