Electrical, structural and electrochemical studies of calcium salt-agarose based gel polymer electrolyte with the addition of natural deep eutectic solvent / Noraishah Syuhada Mohd Rafi

Current interest in divalent calcium-based gel polymer electrolyte systems was rapid growth because of their potential in developing high-energy storage devices such as supercapacitors. However, research in calcium-based electrolytes was still poorly understood regarding the poor ionic conductivity,...
