✦ Synopsis

Weight measurements were used to determme the corrosion rate of the spmes m tubular lead dioxide electrodes with active mass. It was estabhshed that the active mass decreases the corrosion rate on both lead-and leadantimony spmes The spme corrosion rate was determmed under contmuous and dlscontmuous polarization and under charge-discharge cycling. It was found that under contmuous polarixatlon the corrosion rate is lower on lead spines than on lead-antimony ones. The opposite correlation was observed under cyclmg. A determmatlon of the corrosion layer phase composition under various polarization conditions showed that the corrosion layer is very sensitive to polarization conditions despite the presence of active mass.

A theoretical expression has been derived for the dependence of the discharge capacity, C, of the positive plate of the lead-acid battery, on the temperature, T, in the form dlnC/dT = (k -l)(dlnK /dT + l/T), where k is the coefficient of Peukert's equation and K is the specific conductivity of the
