Abstract : The rate of recombination on stand of AgCd cells with Teflonated negative was C/1000. With PVA binder in the cadmium it was lower. Cells containing 3rd electrodes were capable of recombining oxygen generated on overcharge at temperatures from -30 to 140 F. Placing the 3e along the edges of the Cd electrode was more effective than placing against the face of the Cd electrode. Of the cells designed to operate on the argentous level, those with a separator consisting of 3T of FSC charged most rapidly and gave the highest discharge voltage, but the separator was severely attacked by the Pd additive. Discharge voltage in two-level cells is decreased following float; however, cells with thin plates are less affected than those with thick ones. (Author)
