ELECTROCHEMICAL HYDROGEN STORAGE ALLOYS AND BATTERIES FABRICATED FROM THESE ALLOYS

摘要

A disordered electrochemical hydrogen storage alloy and electrochemical cells ha ving a negative electrode comprising this alloy, where the alloy has the composition (Base Alloy)aCobMncAldFeeLafMog where Base Alloy represents a disordered multi-component alloy having at least one structure selected from the group cons isting of: amorphous; microcrystalline; polycrystalline, lacking long-range compositional order with three or more phases of said polycry stalline structure; and any combination of these structures; b is 0 to 7.5 atomic percent; c is 0.1 to 8.5 atomic percent d is 0 to 2.5 atomic percent; e is 0.1 to 6.5 atomic percent; f is 0 to 4.5 atomic percent; g is 0 to 6.5 atomic percent; b + c + d + e + f + g > 0; and a + b + c + d + e + f + g = 100 atomic percent.
