(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.
Researchers, including Wang et al., first fabricated high-performance graphene/S cathode materials by a direct mixing and melting process. Although the initial battery performance was not impressive, these materials opened a new door for researchers to improve battery performance.
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.
Graphene has been used as an efficient scaffold for the S cathode in lithium-sulfur batteries, due to their high gravimetric capacity, elevated theoretical energy density, and utilization of non-toxic materials. With rapid progress in battery development, Li-S batteries have attracted researchers for these reasons.
However, every type of carbon material has a different impact. Furthermore, the mechanism of performance improvement must be clarified. In the present work, graphene was added into a negative active material (NAM) used in a battery cell. The cell was tested under a partial state of charge condition at an extreme discharge cycle.
