Dependence of the Resource of Batteries from the Inequality of the Original Electrotechnical Properties of Their Elements

The nature of changes in the technical state of storage batteries and the relationship between its resource and the uneven physical and chemical properties of its individual cells are studied in the article. The methods and devices aimed at reducing the initial nonuniformity of the parameters of the same battery elements are considered. The results of analytical and experimental studies of the effect on the resource of the indices of the same elements in the composition of the battery are presented. It is proved that the criterion for estimating the resource capabilities of a battery is the unevenness of the physicochemical parameters included in its composition, the decrease in its magnitude exponentially increases its service life.
