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.
Vangapally et al. studied the use of boron-doped graphene nanosheets (BGNS) as a lead-acid battery negative electrode additive to reduce the HER of the negative electrode and inhibit sulfation.
