Metal Hydride alloy powders for high power applications

In the past metal hydride materials, based on AB5 type alloys have been optimised in regard to their maximum hydrogen storage capacity and their cycling stability in alkaline solutions. During the project the electrochemical reaction kinetics of such alloys could be improved remarkably by application of special powder manufacturing techniques. High kinetics metal hydride alloy powders of the AB5 type system have been manufactured in laboratory scale. The surface active species, responsible for fast reaction kinetics, have been identified. Based on the gained knowledge the manufacturing processes have been scaled up from laboratory to a semi-industrial production scale; a further up-scaling into large industrial scale is in progress.
