• Increased utilization of lead oxide core and increased electrode structural integrity. Abstract Graphene nano-sheets such as graphene oxide, chemically converted graphene and pristine graphene improve the capacity utilization of the positive active material of the lead acid battery.
This study focuses on the understanding of graphene enhancements within the interphase of the lead-acid battery positive electrode. GO-PAM had the best performance with the highest utilization of 41.8%, followed by CCG-PAM (37.7%) at the 0.2C rate. GO & CCG optimized samples had better discharge capacity and cyclic performance.
The plethora of OH bonds on the graphene oxide sheets at hydroxyl, carboxyl sites and bond-opening on epoxide facilitate conduction of lead ligands, sulphites, and other ions through chemical substitution and replacements of the −OH. Eqs. (5) and (6) showed the reaction of lead-acid battery with and without the graphene additives.
Hence, we expect that using lead-carbon metal material can be avoided the destruction of current leads due to intergranular corrosion, which is peculiar to the alloy used today Pb–Ca, Pb–Sb, Pb–Sn, which will increase lifetime of lead acid battery. 2. Experimental
Thus, the attached and porous lead/graphite composite electrode can ensure a stable output of electrical conduction and electrolyte diffusion . Carbon in the form of an ionic liquid (IL) has been used as a promising material to further improve LABs.
The lead acid battery comprises a battery shell, a positive plate grid, a negative plate grid, a partition board and electrolyte, wherein the positive and negative plate grids are positioned in the battery shell; the partition board is positioned between the positive and negative plate grids; and the electrolyte is filled into the shell.
