MERCURY CELL BATTERY INVESTIGATION.

Abstract

X-ray analyses of the Pd-Hg alloy positive electrode material show a complicated structure. A paste of the Pd-Hg alloy powder has been applied to supporting screens to successfully eliminate the positive electrode disintegration which has been encountered during cycle testing. The evaluation of two negative electrodes simultaneously is a useful method for studying zinc electrode deterioration resulting from downward sloughing. Organic binders in small amounts (1%) have not been effective in minimiz ing this problem. Small button type cells con structed with the Pd-Hg electrode material have completed 2200 cycles on the simulated 90 minute orbit. Additional data have been accumulated to aid in designing an experimental battery. In herent difficulties, such as frequency dependence and capacitance variable with time, limit the value of impedence bridge capacitance measuring methods to determine the true surface area.
