Development of improved plaque material for aerospace nickel-cadmium cells Final progress report, 17 Nov. 1969 - 17 Nov. 1970

Porous nickel electrodes were fabricated with a honeycomb structure providing direct connection of each pore to the surface of the electrode in order to extend the life of sealed nickel--cadmium cells. Procedures were developed for electroforming thin (0.2 to 0.4 mm) nickel foils with corrugations 3 to 10 mm wide, and for constructing mechanically strong honeycomb plaques from corrugated and flat nickel foils.
