PURPOSE:To suppress the rise of the inner resistance by adding nonaqueous copper sulphate into the anode of a nonaqueous electrolyte cell using cupric oxide as an anode active material so that the remaining moisture in the cell is absorbed by the nonaqueous copper sulphate. CONSTITUTION:80g of reagent special class cupric oxide, 5g of nonaqueous copper sulphate, 10g of acetylene black, and 5g of fluororesin are mixed and the mixture is molded under pressure in an anode inside can 3, then it is dried and is pressed in contact with the inner bottom of an anode can 4. Next, it is faced through a separator 7 impregnated with an electrolyte to a cathode 2 made of lithium and stuck to a cathode can 5 through a current collector 6, and they are sealed to form a nonaqueous electrolyte cell. Accordingly, the remaining moisture in the cell is absorbed by nonaqueous copper sulphate under reaction, thus suppressing the reaction between lithium oxide and water, thereby the rise of the cell inner resistance caused by the remaining moisture can be prevented. |
