Abstract:

Electrochemical investigations were directed toward evaluation of 1.0 A.H. cylindrical Ni-Cd sealed cells containing pasted negative plates. The investigation also includes an evaluation of the data gathered on 1.0 and 4.0 A.H. cells that were life-cycled at the 5-hour charge rate for 200 cycles. In addition, investigations are included that evaluate charging efficiencies of the sintered positive, sintered negative, and pasted negative plates at the five-hour charge rate. Mechanical investigations were directed towards pressure tests and stress analysis of 0.016 in. thick cylindrical cell cases, geometric progression of cylindrical cells down to 0.5 A.H., geometric proportions of 4.0 A.H. rectangular cells, and battery packaging of a 6 volt, 4.0 A.H. rectangular battery with rectangular cells. Stress analysis data are not conclusive enough to determine a numerical value of unit stress. Author
