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
Graphene batteries can preserve strong electricity output inside a variety of temperatures; The lead acid battery is tough to output constantly inside the temperature variety. Graphene batteries have a speedy charging function, which substantially reduces the charging time; Lead-acid batteries generally take more than 8 hours to charge.
Graphene batteries have a speedy charging function, which substantially reduces the charging time; Lead-acid batteries generally take more than 8 hours to charge.

(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.
The test results show that the low-temperature performance, charge acceptance, and large-current discharge performance of the batteries with graphene additives were significantly improved compared to the control battery, and the cycle life under 100% depth of discharge condition was extended by more than 52% from 250 to 380 cycles.
When used as a composite in electrodes, graphene facilitates fast charging as a result of its high conductivity and well-ordered structure. Graphene has been also applied to Li-ion batteries by developing graphene-enabled nanostructured-silicon anodes that enable silicon to survive more cycles and still store more energy.
