This program successfully incorporated new improved electrode fabrication procedures into a small scale pilot production facility and produced advanced lightweight aerospace nickel-cadmium cells. The objectives of achieving a minimum energy density of 20 WHrlb with the 50 AH sealed nickel-cadmium cells was accomplished and two pilot production runs demonstrated that this objective was reached with reproducible results and good yields. The first portion of the program was the investigative phase in which theoretical and analytical studies were performed. The plaque formation process was optimized in respect to sinter porosity and loading level using an electrochemical impregnation technique. In order to develop the optimum cell design, the knowledge obtained from the investigative phase was successfully applied to a mathematical cell design model that was translated into computer language. A computer design of several cells that met the program objectives was then developed.
