The chemistry of the rechargeable system Li/LiAlCl{sub 4}{center_dot}xSO{sub 2}/C (where x = 2.8 to 6), which has an open-circuit voltage of 3.2 V, was investigated and compared with that of Li/LiGaCl{sub 4}{center_dot}xSO{sub 2}/C, which has an open-circuit voltage of 2.9 V. Cyclic voltammetry, pressure measurements, elemental analysis, and vibrational spectroscopy were used to monitor the cycling behavior and the nature of the discharge products. For the LiAlCl{sub 4} based electrolyte, the discharge products were LiCl and an amorphous complex believed to be LiAl{sup III}Cl(SO{sub 2}){sub 3}. For LiGaCl{sub 4} the solid discharge products were LiCl and a sulfur oxide species of the from S{sub n}O, where n is believed to be in the range of 6 to 10.
