Abstract

PURPOSE:To obtain a positive electrode which is easy to form and of good discharge characteristics by forming a porous cupric oxide positive electrode by sintering a mixture of cupric oxide powder and lithium carbonate at a specific temperature. CONSTITUTION:A mixture of cupric oxide powder and lithium carbonate is sintered at a temperature below the melting point, 1,026 deg.C, of the cupric oxide and above the melting point, 618 deg.C, of lithium carbonate to manufacture the porous cupric oxide positive electrode 5. The preferred content of lithium carbonate is 1.5-3.0mol% and the preferred porosity of the molding is 35-40%. For example, 55mg of a 98:2 (molar ratio) mixture of cupric oxide powder and lithium carbonate is molded into a disk of 4.2mm. in diameter and 1.0mm. in thickness, and then the molding is baked at 800 deg.C for 5hrs in the air to obtain a positive pole of a porosity of 37%. Thus, a positive pole for organic electrolyte cells which has a liquid keepability, a wide reactive surface area, good discharge, and characteristics, and which contains no binder and conductor can be obtained.
