Almtrmt-The

optimum conditions of formation for tubular lead/acid battery were studied by experimental design method. Electrode capacity was found to be maximum at a H,SO, concentration of 1.06 sp. gr., a charge amount of 150% theoretical capacity, a charge time of 36 h at a current density of 0.54 A dme2, and an electrolyte temperature of 50Β°C. The polymorphism and the composition of various lead compounds in tubular positive electrode were analysed with X-ray diffraction method after soaking, curing, formation discharging and recharging. Finally, the binding energy of Pb. S and 0 elements of tubular positive electrode was also analysed with X-ray photoelectron spectroscopy method.

The first-cycle discharge capacity of tubular positive plates was determined as a function of formation conditions. "Infinite acid volumes" were used and formation conditions were more extreme (up to 152 h, 70 'C, s.g. 1.320 and paste densities from 3.2 to 5.5 g cme3) than those examined in a previo
