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.
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.
