“…On the other hand, there were papers dealing with PAM characteristics, especially changes in the connection or the size of the PAM particles, which was affected by the charging conditions [12][13][14][15]. These papers described how PCL phenomenon was caused by increase of positive plate resistance.…”

“…It is known that the batteries with PbCaSn, PbCa, or Pb grid have the PCL effect and, when they are charged at high rates, have a longer cycle life than those cycled at low charging currents. [2][3][4][5][6][7][8][9][10] The cycle life of the positive plate is a linear function of the initial charging current applied after discharge. 9 If the charge of the plate is performed with a high current, a maximum or a peak appears at the beginning of the potential-time transient.…”

The capacity of the positive plate of the lead-acid battery is determined by the number of the active centers in positive active material (PAM) where the reaction PbO2→PbSO4 proceeds and by the resistance of the interface corrosion layer false(CLfalse)+AMCL (thin PAM layer interconnecting the PAM and the CL). It was established that the number of the active centers is high if the positive plate discharge is performed with low current and if the charge (at the initial period) is performed with high current. During discharge the active centers from the outer layer of the plate are exhausted and the reaction of the PbO2 reduction approaches the inner part of the plate near the interface and the interface itself. If the pH of the pore solution is low the reduction of the PbO2 proceeds to PbSO4. At the subsequent charge with sufficiently high current a maximum appears on the potential transient. When the H2SO4 flux to the interface is impeded, the pH of the solution in the pores in the interface is high and the reduction of the PbO2 proceeds to PbOn false(1
