(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
This research enhances the capacity of the lead acid battery cathode (positive active materials) by using graphene nano-sheets with varying degrees of oxygen groups and conductivity, while establishing the local mechanisms involved at the active material interface.
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.
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.
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.
