NICKEL-CADMIUM BATTERIES
Abstract
Sealed cells of different designs were fabricated, assembled, and tested. Heat from welding the cover to the can frequently damaged the seal. This w s overco e by pplying heat sinking to conduct the heat away from the seal. In fabricating seals for the squat cells, t e cover was rede igned to eliminate shadowing, which prevented proper seal formation. Results indicated that the optimum quantity of electrolyte to improve overcharge was that which completely filled the pores of the separator and plates. Of the various sep rator materi ls ested no woven nylon and nonwoven polypropylene appear d to be the most desirable from the standpoint of over-all performance. E FFORTS TO IMPROVE THE WATT-HOUR EFFICIENCY OF SEALED NICKEL-CADMIUM CELLS RESULTED IN NEGATIVE PLATES WITH IMPROVED OVERCHARGE CAPABILITIES. The complexity of reactions at the negative electrode was demonstr ted. Laboratory type ealed cells were assembled so hat in case of failure they could be disassembled without damaging any of the components. (Author)
