High cyclability energy storage device with optimized hydroxyethyl cellulose-dextran-based polymer electrolytes: Structural, electrical and electrochemical investigations

The preparation of a dextran (Dex)-hydroxyethyl cellulose (HEC) blend impregnated with ammonium bromide (NH4Br) is done via the solution cast method. The phases due to crystalline and amorphous regions were separated and used to estimate the degree of crystallinity. The most amorphous blend was disc...
