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