摘要
The cycling lives of metal hydride electrodes using mischmetal (Mm)-based alloys were significantly impaired by a stoichiometric deviation to the Mm-deficient side, because elements such as manganese and aluminum were preferentially precipitated at grain boundaries. Heat treatment at 1000-degrees-C was effective for improving the cycling lives.
