Abstract (en)
[origin: WO2016130561A1] Hydrogen storage alloys comprising a) at least one main phase, b) a storage secondary phase and c) a catalytic secondary phase, where the weight ratio of the catalytic secondary phase abundance to the storage secondary phase abundance is ≥ 3; or comprising a) at least one main phase, b) from 0 to 13.3 wt% of a storage secondary phase and c) a catalytic secondary phase, where the alloy comprises from 0.05 to 0.98 at% of one or more rare-earth elements, or the alloy comprises for example i) one or more elements selected from the group consisting of Ti, Zr, Nb and Hf and ii) one or more elements selected from the group consisting of V, Cr, Mn, Ni, Sn, Al, Co, Cu, Mo, W, Fe, Si, Sn and rare earth elements, where the atomic ratio of ii) to i) is from 1.80 to 1.98; exhibit improved electrochemical properties at low temperature.
