Ionic conductivity studies on magnesium-based cellulose acetate polymer gel electrolytes / Aniza Omar … [et al.]

Magnesium-based polymer gel electrolytes consist of magnesium triflate (MgTf) salt, a mixture of ethylene carbonate (EC) and diethyl carbonate (DEC) solvents as well as cellulose acetate as a polymeric agent were prepared via direct dissolution method. The highest ionic conductivity obtained for MgT...
