Effects of the agglomerate size of reduced graphene electrocatalyst: Lead acid battery cathode as a case

The effect of reduced graphene electro-catalysts and their the agglomerate sizes, the case in lead acid battery positive active material was done. Reduced graphene size distributions were achieved via shear induced fragmentation of graphene oxide paper followed by hydrazine reduction. Increased size of agglomerates were beneficial when conductive reduced graphene was used as an electro-catalyst, and up to 14% improvements in discharge performance were recorded.
