A dry powder roller pressing process, once developed for making both of the electrodes in low cost Ni-Cd consumer batteries, has been utilized to make electrodes for Ni-MH batteries. The process was evaluated by manually making a series of sub-C type cells that were characterized with respect to specific capacity, cycle life, and self-discharge. The performance was comparable in several respects with that of cells made by more complex Ni-foam technologies.
