Abstract
Various factors affect the performance of storage batteries and can reduce their performance. In practice, it is very difficult to realize the full use of active materials involved in the current generation process. About half of the active mass level does not participate in the reaction with the electrolyte, because they serve as the basis for making the electrode frame and ensure the mechanical strength of the materials. Therefore, the coefficient of real use of active materials ofpositive electrodes is 45-55%, and that of negative electrodes is 50-65%. In addition, a 35-38% solution of sulfuric acid is also used as an electrolyte. Therefore, the actual consumption of materials is higher than the theoretical consumption, and the actual energy volume is somewhat lower. The leakage of the electrolyte from the separator largely depends on its concentration. First, if the density of the electrolyte decreases, its weight decreases, which reduces its flow, but the decrease in density leads to a decrease in viscosity, which increases its fluidity. Therefore, it is desirable to determine the relationship between the concentration of the electrolyte, its distribution over the height of the separator and its fluidity during the experiment. This is a very important factor, as the electrolyte concentration changes after a certain period of time during battery operation, and the optimal concentration of the acid used as an electrolyte plays a major role in ensuring performance. In these studies, the effect of the concentration of the electrolyte used as a working electrolyte on the working efficiency of the batteries as a result of the increase in the pores of the separator and the change in fluidity at different compression levels was studied.
