✦ Synopsis

The effects, during formation, of current density, charge capacity, and concentration and temperature of HzS04 electrolyte on the capacity of tubular electrodes in lead/acid batteries have been studied. Electrode capacity was found to be maximum at a HzS04 concentration of 1.05 sp. gr., a charge amount of 250% theoretical capacity, a current density of 0.44 A dme2, and an electrolyte temperature of 40 "C. A study of the soaking process for tubular electrodes showed the electrode capacity to be maximum when the acid absorption was about 170 mg of H2S04 per g of oxide. Finally, the discharge overpotential of tubular electrodes was analyzed by a galvanostatic transient method.
