Effect of Teflon Emulsion on Hydrogen Electrode Properties and Performance in Nickel-Hydrogen Cells

摘要

The traditional T30 Teflon emulsion used in nickel-hydrogen battery cells is being phased due to EPA concerns with two of its minority components. This presentation reviews work done to date by The Aerospace Corporation to better understand the relationship between the properties of the hydrogen electrode affected by the Teflon emulsion and cell performance. Special cycling tests have been derived to selectively stress the hydrogen electrode with minimum stress to the nickel electrode. Results from these tests performed on cells constructed with T30 and an alternative emulsion, TE3859, are presented. The Aerospace Corporation is gratefully acknowledged for supporting this work as part of the Aerospace Mission-Oriented Investigation and Experimentation (MOIE) program.
