Title
(EN) METAL HYDRIDE ALLOY POWDER FOR NIMH BATTERIES HAVING IMPROVED PROPERTIES, METHOD FOR PREPARING THE SAME, AND NIMH BATTERY WITH IMPROVED PROPERTIES COMPRISING THE METAL HYDRIDE ALLOY POWDER
(FR) POUDRE D'ALLIAGE D'HYDRURE MÉTALLIQUE POUR BATTERIES NIMH AYANT DES PROPRIÉTÉS AMÉLIORÉES, SON PROCÉDÉ DE PRÉPARATION ET BATTERIE NIMH À PROPRIÉTÉS AMÉLIORÉES COMPRENANT LA POUDRE D'ALLIAGE D'HYDRURE MÉTALLIQUE
Abstract
(EN)
The invention concerns a method for improving the properties of metal hydride (MH) alloys for hydride batteries, in particular nickel-metal hydride (NiMH) batteries. It also concerns a MH alloy having improved properties that may be obtained from the method, as well as a NiMH battery having improved properties. The invention furthermore concerns the use of hydrogen peroxide for improving the properties of a MH alloy.
(FR)
L'invention concerne un procédé permettant d'améliorer les propriétés d'alliages d'hydrure métallique (MH) destiné à des batteries à hydrure, en particulier des batteries au nickel-hydrure (NiMH). L'invention concerne également un alliage MH ayant des propriétés améliorées qui peuvent être obtenues à partir du procédé, ainsi qu'une batterie NiMH ayant des propriétés améliorées. L'invention concerne en outre l'utilisation de peroxyde d'hydrogène afin d'améliorer les propriétés d'un alliage MH.
