Abstract:

Special demountable cells were designed, constructed, and tested with rates of discharge as the primary independent variable. Duplicate experiments were performed with groups of five demountable cells. Separate groups were discharged at C2, C, 2C, 4C, and 8C rates. One experiment maintained uniform temperatures of about 25C in all cells. The other experiment had an environmental temperature of 25C, but internal heaters were maintained at 40C. Otherwise, all known variables were held constant. Both groups of cells degraded at a higher rate in measured qualities at higher rates of discharge. Results are discussed.
