Abstract
The objective of this work is to improve the negative electrode of the metal hydride electrodes. Three areas were investigated: corrosion inhibition through Zn additives to the electrolyte, the use of AB5 and AB2 alloy mixtures, and novel AB2 electrode materials. In order to fully understand the processes involved in the corrosion study, tests were carried at Brookhaven National Laboratory using X-ray Absorption Near Edge Spectroscopy. These tests showed that Zn prevented the corrosion of Ni-a major component of these electrodes. AB2 and AB5 alloy mixtures showed longer cycle life and better rate capability. Investigations using novel materials demonstrated systematic differences in electrochemical behavior due to composition changes and great activation time differences due to Pd coatings.
