New Metal-Hydride Electrode Materials Based On RMgNi Alloys for Chemical Current Sources.

We present a brief survey of works on the structure and hydrogen-sorption properties of some R-Mg-Ni alloys. It is shown that R-Mg-Ni alloys can be regarded as promising electrode materials for Ni/MH rechargeable batteries. Main attention is focused on the analysis of the properties of RMgNi alloys. The relationship between the composition of these alloys, character of isotherms, and electrochemical characteristics is discussed. [ABSTRACT FROM AUTHOR]
