Abstract:

The development of 6 sizes of high capacity, vented Ni-Cd cells to meet Signal Corps Requirement SCL-7505A and the manufacture of 300 cells of each of the 6 sizes was completed. All cells were given 3 conditioning cycles during which the capacity at the 5-hr O.2C sub 5 rate was determined for each cell. Capacity tests were made on 6 representative cells of each type at the 0.2C sub 5 rate at 80 and -40 F and at the 3C sub 5 rate at 80 F. Preliminary tests on 36 Type 4 test cells led to the selection of positive plates 0.044-in. thick, negative plates 0.037-in. thick, a nylon taffetacellophanenylon taffeta separator 5-to 6-mil thick. Vacuum impregnation was used for both positive and negative plates and Co about 5 on total metal basis was added to the positive impregnation bath. LiO4 ca. 9 gl was added to the KOH electrolyte to promote initial capacity and possibly increase cycle life. Author
