Gas atomization of Cu-modified AB5 metal hydride alloys
TL;DR: In this paper, gas atomization together with a hydrogen annealing process is proposed as a method to achieve improved low-temperature performance of AB 5 alloy electrodes in Ni/MH batteries and restore the original cycle life which was sacrificed by the incorporation of copper in the alloy formula.
