PURPOSE:To provide a nonaqueous-solvent cell whose voltage drop is small even at the initial stage of large-current discharge, by using an electrolyte subjected to an electrical current treatment by using a pair of an anode of a light metal and a cathode of carbon. CONSTITUTION:Before an electrolyte 13 comprising 1.5mol/l of aluminum chloride and 1.5mol/l of lithium chloride dissolved in thionyl chloride is injected into a can 1 through a tubular anode 10, the electrolyte is subjected to an electrical current treatment with an electrical current of 100mA per 10ml of the electrolyte for 10hr by using a pair of an anode of lithium and a cathode of a porous carbonaceous piece chiefly made of acetylene black. A cell A, which is an embodiment of the present invention and includes the electrolyte 13 subjected to the electrical current treatment before injected into the can 1, undergoes a smaller voltage drop at the initial stage of discharge than a conventional cell B including the electrolyte not subjected to the electrical current treatment, as shown in the drawing. |
