Abstract:
The processes that control the useful life time and performance rates in non-flowing zinc electrodes for electrical storage batteries have been investigated. In particular, the chemical reaction rates, concentration, and electrical potential distributions have been predicted theoretically and measured experimentally as functions of position in the electrode and time for both charge, discharge, and multiple cycles. Changes in crystal structure and solid distributions have also been measured and examined theoretically. Similar rates and distributions have been measured and correlated for RAI P2291 ion exchange membrane separators used in zinc secondary batteries such as the nickle-zinc battery AnKOH, H2ONiOOH. Distributions in flow through electrodes were also observed experimentally and calculated theoretically, using the copper deposition reaction for experimental convenience. Work was begun on the theoretical description of the nickle oxide electrode. Experimental work is being planned to validate and revise our understanding of how the nickel electrode operates. Work is continuing on measurement of concentration profiles in zinc electrodes. Author
