Abstract
Lithium-cycling efficiencies and corrosion rates were measured in half cells. The elaborated inorganic electrolyte solution, consisting mainly of LiAlClsub4 and SOsub2, has a conductivity of 2.2 mS/cm at -25 degree Celsius and 98 mS/cm at 60 degree Celsius. Lithium-cycling efficiencies of about 98 percent at 40 mA/qcm for at least 50 cycles were achieved. Depending on improved electrolyte preparation, the current density for the lithium corrosion could be reduced from 12.1 to 6.5 myA/qcm. The results indicate stability, compatibility and high rate capability of the system lithium/inorganic electrolyte solution.
