Abstract

PURPOSE:To obtain a cell excellent in the cycle life and leakage resistance by specifying the quantity of a nonaqueous electrolyte against the theoretical discharge capacity of a positive electrode. CONSTITUTION:Manganese dioxide is used for a positive electrode 1 and a fusible alloy adsorbing end desorbing lithium is used for a negative electrode 4, lithium salt is solved in a mixed solvent of propylene carbonate and 1,2- dimethoxyethane for a nonaqueous electrolyte, the electrolyte quantity is set to 4.3mg/mAh-5.2mg/mAh against the theoretical discharge capacity of a positive electrode active material. The negative electrode alloy 4 is pulverized during the repeated charge and discharge, but when the electrolyte quantity is within the optimum range, even if part of the electrolyte is absorbed by generated cracks, the electrolyte in a separator 8 is not drained, and no electrolyte overflows at the time of sealing. A cell with the excellent cycle life and leakage resistant is thereby obtained.
