Special Tests and Destructive Physical Analyses Procedures as Used by the Aerospace Corporation with Nickel-Hydrogen Cells,
Abstract
The destructive physical analysis (DPA) of electrochemical devices is an important part of the overall test. Specific tests have been developed to investigate the degradation mode or the failure mechanism that surfaces during the course of a cell being assembled, acceptance tested, and lifecycle tested. The tests that have been developed are peculiar to the cell chemistry under investigation. Tests are often developed by an individual or group of researchers as a result of their particular interest in an unresolved failure mechanism or degradation mode. This report addresses a series of production, operational, and storage issues that have been addressed by the Electrochemistry Group at The Aerospace Corporation, mostly under the direction of Dr. Albert Zimmerman. As a result of these investigations, as well as associated research studies carried out to develop a clearer understanding of the nickel oxyhydroxide electrode, a series of unique and useful specialized tests has been developed.
