ELECTROCHEMISTRY OF HYDRIDE-FORMING INTER METALLIC COMPOUNDS AND ALLOYS

The present review deals with studies published over recent 15 years a nd devoted to the electrochemistry of hydride-forming intermetallic co mpounds (IMC) and alloys. Data on the discharge capacity and the stabi lity at potential cycling of electrode materials based on IMC and AB, AB(2), AB(3), and AB(5) types alloys and their substituted derivatives are classified and generalised. The problems concerning the optimisat ion of the elemental composition of IMC and alloys, their production a nd activation, as well as the factors causing degradation of electrode s manufactured on their basis are discussed. The mathematical models s uggested for describing the processes of discharge and degradation of metal-hydride electrodes are analyzed.
