Original Abstract

Our contribution deals with the study of surface processes and chemical composition on the surface of the negative electrode of a lead-acid battery during cycling at different speeds. Thin electrodes were created for the measurements. The negative electrode was analyzed at six SOC states (100 %, 80 %, 60 %, 40 %, 20 % and 0 % SOC). The proportion of individual elements on the surface of the negative electrode during cycling at 0.2 C was evaluated. Chemical changes occurring on the surface of the negative electrode during cycling of the lead-acid battery were studied using an X-ray diffractometer and the presence of individual chemical elements on the surface of the electrode was evaluated using the Rietveld method. An increase in the material was observed, which did not convert during cycling and caused a more significant conversion of material near the negative electrode collector during cycling.
