Abstract : Pd additions to the Ag positive plates of 0.2, 0.5, and 1% were tested in 25 amp/hr cells on the 2-hr cycle period. It was found that 1% Pd addition produces the maximum monovalent charge capacity of 50% and retains this level for approximately 200 cycles. Ag powders of different particle size were incorporated into 2 amp/hr cells an preliminary cycle data was obtained. Negative plates containing polyethylene oxide and polyvinly alcohol are on the 2-hr cycle program. Five hundred cycles at 25% depth of discharge have been reached to date. Hydrogen evolution data was obtained from zinc negative plates containing 1, 2, and 4% HgO in various concentrations of KOH for a 2-wk period. (Author)
