Abstract
Positive plates manufactured with pastes exhibit high stability of their active mass structure ensuring long cycle life of the plates during battery operation. Since crystals are large in size, their oxidation to is strongly impeded; hence, the plates have low initial capacity. This has restricted the wider application of pastes in battery production. The present paper suggests the preparation of pastes in the presence of . Three types of pastes are proposed depending on the method of introduction into them: (i) a mixture of and , (ii) obtained in the presence of , and (iii) predecomposed with and then used for the preparation of pastes. The processes occurring during paste preparation are followed and its structure and crystal morphology are determined. By testing of batteries manufactured with plates prepared by the above methods, their initial capacity was measured to be above 100% and the battery life was established to be considerably longer than that of batteries produced with classical pastes generally used in the battery industry. These features allow the wider application of pastes in battery production.
