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.
In terms of charging speed, the graphene battery currently on the market refers to a lithium battery mixed with graphene material, not a pure graphene battery. The arrangement structure allows electrons to pass through quickly, allowing the use of graphene batteries to have an extremely fast charging speed.
They are square in shape, large and heavy. Compared with lead-acid batteries, graphene batteries are smaller in size and lighter in weight under the same power. The volume and weight of lithium batteries are one-third of that of lead-acid batteries under the same power.
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.
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.
