The service life of lead-acid batteries is often limited by disintegration of the positive active mass structure. It is known that the latter depends on the phase composition, crystal morphology and paste density. In general, the electrode whose active mass is prepared from 4PbO·PbSO4 pastes (denoted by 4BSpas) has about 30% longer cycle lives than those obtained by 3PbO·PbSO4·H2O. Therefore, the...
