HYDROGEN STORAGE ALLOYS

摘要

Hydrogen storage alloys comprising a metal oxide containing ≥ 60 at% oxygen; and/or comprising metal regions separated by a boundary region, which boundary region comprises at least one channel; and/or comprising metal regions separated by a boundary region, where the boundary region has a length and an average width, where the average width is from about 12 nm to about 1 100 nm; and/or comprising a metal oxide zone comprising a metal oxide, which oxide zone is aligned with at least one channel; and/or comprising a Ni/Cr metal oxide have improved electrochemical properties, for instance improved low temperature electrochemical performance.
