Rechargeable cell, which is sealed from the external atmosphere, having a negative electrode of, for example, LaNi5 or an intermetallic compound derived therefrom wherein the negative electrode has a greater quantity of electrochemically active compound than the positive electrode. When the positive electrode is in the fully discharged state, the excess quantity of active compound at the negative electrode is partly in the charged state (that is to say, being partly in the hydride form.).
