Abstract:

This report is the first of a series of papers that describe work done in these laboratories toward development of a 20 watt-hours per pound and 2 watt-hours per cubic inch Nickel-Cadmium battery cell. State-of-the-Art cells have been delivering typically 12 to 16 watt-hours per pound and about 1.5 watt-hours per cubic inch at 100 depth of discharge using the two hour rate. This paper describes the relationship between nickel sinters and nickel hydroxide active material necessary to achieve these goals. A theory on utilization of active material is presented. Data are given showing an optimum porosity exists, but deviations between 77 and 85 percent are not very significant. A hypothesis is given to account for blistering and thickening of nickel hydroxide electrodes. Author
