The importance of observation of structural changes of lead acid battery active mass in special applications in the mining industry

Original language description

To be able to use lead acid batteries in particularly difficult conditions in the mining industry, it is very important to understand of the events that occurs during traction operation of mining carts, or auxiliary lighting. Failure of lead accumulators in the hazardous environments, where it is desired nonexplosive embodiment, may have fatal consequences. The paper describes the possibility of observing changes in active materials at the microscopic level. The process of charging and discharging lead-acid accumulator has been described in many publications. The aim of this article is supplement known information about a series of images and analysis that will accurately show progressive changes in the structure of the negative electrode. Negative electrodes are, at each cycle, charged and discharged under the same conditions, scanned with a scanning electron microscope, it is performed elemental analysis (EDS) and is measured size of the individual sulfate crystals. Previous measured results indicate that during the charging the conversion of PbSO4 crystals into a charged form of the active mass is not complete and there is a rapid increase in the size of lead sulfate crystals on the negative electrode. This article compares changes in electrode surface composition after two cycles. There is clear loss of lead and on the other hand visible growth of sulfur. This indicate progressive surface sulfation.
