Chemical and Electrochemical Properties of Potential Battery Systems in Room Temperature Molten Salts

Abstract

Aluminum electrodes were studied in basic and acidic melts. Dissolution was possible in both environments, but deposition was possible only in acidic melts. Extensive studies in acidic melts indicated that the exchange current density was relatively low (even at approx. 100C, it was approx. 1 mA/ sq. cm) and that some passivation occurred at high current densities/ overpotentials. However, the dissolution behavior at moderate rates (< or = mA/ sq. cm) indicated relatively low polarization (sufficient for battery applications).
