DEVELOPMENT OF MANUFACTURING METHODS AND TECHNIQUES FOR THE PRODUCTION OF IMPROVED ALKALINE BATTERIES.
Abstract
A development program directed at the problem of producing improved sealed alkaline batteries with matched cell capacities + or - 1% of nominal ampere-hour rating is described. The required properties of cell components are reviewed, and methods of fabrication along with cell designs are presented. The + or - 1% matching in cell capacity was attained with five-cell sealed 14 ampere-hour nickel-cadmium batteries and five-cell sealed 15 ampere-hour silver-cadmium batteries on short orbit cycling regimes. For the silver-cadmium battery the + or - 1% capacity was attained through 535 cycles on the short orbit regime up to 75% depth of discharge. Short orbit cycling data of sealed 15 AH - Ag/Cd battery cells are presented and discussed. The batteries deliver a minimum capacity of 11.5 AH at -10 F, at the rates employed at the 75% depth of discharge, and a maximum of 20.7 AH at 150 F, at the rates employed at 25% depth. The 14 AH - Ni/Cd battery cells deliver a minimum capacity of 5.7 AH at -30 F, at the rates employed at the 75% depth of discharge, and a maximum of 14.8 AH at 75 F, at the rates employed at 25% depth.
