Xrd Analysis Of Chemical Composition On Lead Surface Microelectrodes

Abstract

This work is focused on the observation of changes in the chemical composition on thesurface of the negative electrode of the lead-acid battery using an XRD diffractometer. The measurementwas performed on thin pasted electrodes with a thickness of about 1mm. After the maturationand molding process, the fully charged negative electrode was gradually discharged andcharged at a rate of 0.2 C and 0.3 C. The negative electrode was analyzed at 100 %, 80 %, 60 %, 40% 20 % a 0 % SOC states. Chemical changes occurring on the surface of the negative electrode duringdischarging and charging of the lead-acid battery were measured using X-ray diffractometerRigaku MiniFlex HR 600.
