The Fig. 6 is a model used to explain the ion transfer optimization mechanisms in graphene optimized lead acid battery. Graphene additives increased the electro-active surface area, and the generation of −OH radicals, and as such, the rate of −OH transfer, which is in equilibrium with the transfer of cations, determined current efficiency.
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.
