Galvanic cells were tested using as electrolytes room temperature molten salts formed by mixing AlCl/sub 3/ with 1-methyl-3-ethylimidazolium chloride (MEICl). Zn and Cd, each with basic melt (containing Cl/sup -/ and AlCl/sub 4//sup -/) were the anodes. Br/sub 2/ dissolved in basic melt with a reticulated vitreous carbon current collector was the cathode in each case. MEI/sup +/-selective Nafion was used as a separator. The Zn electrode was found to be irreversible, while the Cd/Br/sub 2/ cell is rechargeable with an open-circuit voltage of 2.0V, an extended temperature range of operation, and potential for high specific energy.
