Gel ¿ Crystal Theory Dissolution Precipitation MechanismGraphene Nano-Sheet EnhancementsEffect of Size and Reduction of GrapheneShear Induced Fragmentation of Graphene InterConductivity and Electro-Osmotic PhenomenaNovel Strategies for Utilization and Capacity improvement in Lead Acid Battery Technological demands in hybrid electric vehicles, 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. The combination of cathode materials with tailored graphene based additives. Electrochemical interaction of the graphene sheets which changed the reactivity of lead dioxide crystals in the gel zone. Ion transfer model was developed showing the optimization of gel zone ion transfer induced by the electrochemical activity of graphene additives. The mechanistic interfacial characteristics of graphene enhancements in LABs were further evaluated based on the capacitance of the double layer and charge transfer resistance.
