Electrochemistry of hydride-forming intermetallic compounds and alloys

The present review covers studies published over the past 15 years on the electrochemistry of hydride-forming intermetallic compounds (IMC) and alloys. Data on the discharge capacity and stability of electrode materials based on IMC and AB, AB₂ , AB₃ and AB₅ type alloys and their substituted derivatives during potential cycling are classified and generalised. The problems concerning the optimisation of the elemental composition of IMC and alloys, their production and activation as well as the reasons for the degradation of electrodes based on these materials are discussed. The mathematical models suggested for describing the processes of discharge and degradation of metal hydride electrodes are analysed. The bibliography includes 149 references.
