Interconnected graphene networks as novel nano-composites for optimizing lead acid battery

Interconnected graphene/PbO composites appearing sand-wish was developed for lead acid battery cathode. Facile processing technique which is solution based, enabled the interaction between graphene oxide nano-sheets and PbO submicron particles under mechanical stirring producing sand-wish-like structures containing graphene nano-sheets. The affinity and interaction between graphene oxide and PbO in solution were marked by changes in graphene surface chemistry. Electrodes appeared porous and interconnected, and recording approx. 15% increase in discharge performance.
