Abstract : Studies on the effect of plate thickness on sealed cell behavior showed that thin-plate cells performed better at high rates. The improved performance of such cells is the result of reduced polarization, which is the predominant factor in determining cell voltage and capacity at high rates. A heavier plate backing support (and consequently, a more uniform plate current distribution) appears to have a greater effect on thin-plate cells when such cells are discharged at high rates. A Cd/Cd(OH)2 coulometer, at high rates, behaves similarly to a nickel-cadmium cell, and an average voltage drop of 0.7 volt can be expected from a coulometer constructed with 0.035in. plates, during the first minute of a 600 ampere discharge. A breadboard model of the charge control circuit functioned properly, at medium currents, showing that the basic design of the circuit is correct.
