A study has been conducted of the effect on the electrical performance of lead–acid batteries when adding different electrochemically active carbons to the negative plates. The possibility of a synergistic effect by using activated carbon as well as carbon black has been explored. The presentation shows how mapping images obtained with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) assist in the elucidation of the mechanism by which electrochemically active carbons influence the processes that take place at the negative plates.
