The plethora of OH bonds on the graphene oxide sheets at hydroxyl, carboxyl sites and bond-opening on epoxide facilitate conduction of lead ligands, sulphites, and other ions through chemical substitution and replacements of the −OH. Eqs. (5) and (6) showed the reaction of lead-acid battery with and without the graphene additives.
(5) and (6) showed the reaction of lead-acid battery with and without the graphene additives. The presence of graphene reduced activation energy for the formation of lead complexes at charge and discharge by providing active sites for conduction and desorption of ions within the lead salt aggregate.
In this article, we report the addition of graphene (Gr) to negative active materials (NAM) of lead-acid batteries (LABs) for sulfation suppression and cycle-life extension. Our experimental results show that with an addition of only a fraction of a percent of Gr, the partial state of charge (PSoC) cycle life is si
