Abstract

PURPOSE:To obtain a nonaqueous electrolyte battery of the 1.5V system having a negative electrode containing lithium, sodium or the like as an active material and which is excellently interchangeable with an existing silver or mercury battery by using a positive electrode which contains a copper-lead compound oxide as an active material. CONSTITUTION:Mixture consisting of cupric oxide and trilead tetroxide in a molar ratio of 18:1 is put in an alumina crucible and sintered in air at 700 deg.C for 20hr to obtain a sintered mixture. Next, the sintered mixture is crushed in a mortar before the crushed mixture is sieved so as to obtain a positive active material which can pass through a sieve of 400 mesh. After the thus obtain active material is mixed with graphite powder used as a conductive agent and fluorine resin powder used as a binder in a ratio of 80:15:5 (by weight), the mixture is molded before being thermally treated at 300 deg.C for one hour, thereby making a positive electrode. A negative electrode is made by punching a rolled lithium plate into a given dimension. Electrolyte is prepared by dissolving lithium perchlorate in a mixture solvent composed of equal volumes of propylene carbonate and 1,2-dimethoxyethane. A separator consisting of a nonwoven polypropylene fabric is impregnated with the above electrolyte. As shown by graph A, this battery has a discharge voltage of around 1.5V indicating that it is interchangeable with an existing silver or mercury battery.
