Abstract :
We have studied the effect that solute chemistry has on the cyclic lifetimes of AB5 alloys in rechargeable cells. The results of a large number of measurements of cycle lifetimes of LaNi5-xM x electrodes are compiled. Correlations are made between the lifetimes, characterized by an exponential decay, and properties of the alloys and their constituents. It is found that the lifetimes show a strong dependence on the formation enthalpy of La with Ni1-x/5Mx/5 and a weak dependence on alloy volume expansion on hydriding
