  • ACTIVE MATERIAL FOR A NEGATIVE ELECTRODE OF AN ALKALINE ACCUMULATOR OF THE NICKEL-METAL HYDRID TYPE
    Publication number: 20120134871
    Abstract: A hydridable alloy of formula R1-x-yMgxMyNis-aBa wherein R is selected from the group consisting in rare earths, yttrium and a mixture thereof; M represents Zr and/or Ti; B is selected from the group consisting in Mn, Al, Co, Fe and a mixture thereof; 0.1<x<0.4; 0?y<0.1; 3<s<4.5 and 0?a<1; at least 5% of the volume of which consists of a stack of sequences of a pattern of the A2B4 type and of n patterns of the CaCu5 type randomly distributed along one direction, n being an integer comprised between 1 and 10 and representing the number of patterns of the CaCu5 type per pattern of the A2B4 type. A method for making a hydridable alloy comprising steps for compression and applying a current through a mixture comprising Mg2Ni and a compound comprising nickel and one or several elements selected from the group consisting in rare earths and yttrium.
