Our research into enhancing Lead Acid Batteries with graphene commenced in 2016. The initial motive of the project was to enhance the dynamic charge acceptance of the negative active material.
• Increased utilization of lead oxide core and increased electrode structural integrity. Abstract Graphene nano-sheets such as graphene oxide, chemically converted graphene and pristine graphene improve the capacity utilization of the positive active material of the lead acid battery.
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
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.
After years of extensive research, we came to understand that graphene not only improves charge acceptance but also improves and enhances other key aspects of the battery. In collaboration with the largest battery manufacturer in Sri Lanka, we introduced the world’s first Graphene Enhanced Led Acid Battery in 2022.
Technological demands in HEVs, large scale storage and portable power stations has furthered more research interests in Lead Acid Batteries (LAB), in addition to the advantage of power rating per cost. The LAB positive active materials (PAM), due to low utilization and life cycle, severely limits the competitiveness of the traditional battery.
