Chemical Changes During Cycling on the Surface of the Negative Electrode of Lead-Acid Batteries

Popis výsledku v původním jazyce

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, 0.3 C and 0.5 C was evaluated. Chemical changes occurring on the surface of the negative electrode during cycling of the lead-acid battery were measured using an X-ray diffractometer, and the presence of individual chemical elements on the surface of the electrode was evaluated using the Rietveld method. At higher cycling speeds, an increase in the material was observed, which did not convert during cycling, and higher cycling speeds caused a more significant material conversion near the negative electrode collector.
