Three primary cells (a, b, and c) and two secondary cell candidates (d and e) were examined using room-temperature molten salts as electrolytes in each case: (a) A1 anode / A1Cl3-MEIC1 (N=0.37) // FeCl3-MEIC1 (N=0.33) / W cathode (b) A1 anode / A1Cl3-MEIC1 (N=0.37) // WCL6-MEIC1 (N=0.33) / W cathode (c) A1 anode / A1Br3-MEIBr (N=0.33) / BR2 / RVC, Pt cathode (d) Zn anode / A1Cl3-MEIC1 (N=0.33) // A1Cl3-MEIC1 (N=0.60) / A1 cathode (e) Cd anode / A1Cl3-MEIC1 (N=0.33) // A1Cl3-MEIC1 (N=0.60) / A1 cathode. All cells except (c) used electrolytes containing 1-methyl-3-ethylimidazolium chloride (MEIC1), where N is the mole fraction of aluminum halide in the melt. Cell (c) used electrolytes containing 1-methyl-3-ethylimidazolium bromide (MEIBr). An IONAC anion exchange membrane separated the anolyte and catholyte solutions in cells (a) and (b), while in cells (d) and (e) a NAFION cation exchange membrane separated the anolyte and catholyte solutions. In cell (c) a phase boundary separated the anolyte and catholyte solutions, with reticulated vitreous carbon (RVC) acting as the anode current carrier.
