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

摘要

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.
