The effect of lime (Citrus aurantifolia Swingle) electrolyte filtrate addition on conductivity and electricity of hydrogel aluminium battery based on carboxymethyl cellulose

Hydrogel Aluminum Battery is a promising source of electrical energy using electrolytes polymeror hydrogel. This research aims to determine the effect lime electrolyte addition on ionic conductivity and electrical characteristic values of hydrogel aluminium battery produced. The method used for making hydrogel is gelatinization method. Based on this research, the best conductivity value obtained is 3.968 x10^-3 S/cm from the combination of CMC 2% on the addition of 100 ml. The highest voltage obtained from hydrogel aluminium battery is 1.6129 from the combination of CMC 2% on the addition of 100 ml electrolyte. The highest DC current is 14.077 mA from the combination of CMC 2% on the addition of 100 ml and the highest battery power obtained is 22,805 mW from the combination of CMC 2% variation at the addition of 100 ml electrolytes.
