Estimating the term…
A modified Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy which has at least one of the following characteristics: 1) an increased charge/discharge rate capability over that the base Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy; 2) a formation cycling requirement which is reduced to one tenth that of the base Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy; or 3) an oxide surface layer having a higher electrochemical hydrogen storage catalytic activity than the base Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy.
A hydrogen storage alloy consisting of, in atomic percentage 0.1 to 60% Ti, 0.1 to 40% Zr, 0<V<60%, 0.1 to 57% Ni, 5 to 22% Mn, 0<Cr<56, Sn, Al, Co and optionally Fe.
A modified Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy comprising, in atomic percentage:
In a method of casting an ingot of a modified Ti—V—Zr—Ni—Mn—Cr electrochemical hydrogen storage alloy comprising, in atomic percentage (Base Alloy)aCobFecAldSne, where said Base Alloy comprises 0.1 to 60% Ti, 0.1 to 40% Zr, 0<V<60% , 0.1 to 57% Ni, 5 to 22% Mn and 0 to 56% Cr;
