Abstract
PURPOSE:To raise storing characteristics by subjecting manganese dioxide positive pole to a dehydrating treatment involving freezing and drying for a cell using a nonaqueous non-protonic organic electrolyte. CONSTITUTION:The positive pole 5 is manufactured by mixing electrolytic manganese dioxide heat-treated at approx. 400 deg.C in the air with acetylene black and a fluorine-containing resin tackifier, forming the mixture into a disk, and then housing the disk in a freezing and drying flask for dehydration. The preferred temperature of freezing and drying is 0--80 deg.C. For example, the disk is sufficiently cooled in a dry ice-methanol bath of approx. -78 deg.C and then dried under a reduced pressure of 10<-4>mmHg. And, as the negative pole 4, a light metal, e.g., lithium, etc., is used.
