Electrochemical cell comprising a hydride-forming intermetallic compound |
摘要 |
A rechargeable electrochemical cell having a negative electrode (6), whose electrochemically active material comprises an intermetallic compound having the CaCu5-structure which forms a hydride with hydrogen, obtains a high loadability and a long life cycle by virtue of the fact that the intermetallic compound comprises a non-stoichiometric metastable phase. The intermetallic compound is, preferably, of the type having the composition ABm, where m exceeds 5.4. <IMAGE> |
