We think that graphite materials will be more advantageous than gold as current collector for lead acid batteries because of cost reduction, weight reduction and improvement of transportability. Furthermore, the use of graphite materials do not reduce recyclability.
It was indicated that graphite sheet can be very promising material for low cost and large size cathode current collector of lead acid battery with high performance. The starting material of flake graphite was soaked in mixed solution of sulfuric acid (98%) with 5% hydrogen peroxide (30%) to get sulfuric graphite of layers compound.
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
The lead acid battery with current collector of expanded natural graphite sheet containing 5% polypropylene (PP) can repeat deep charge and discharge between 0 and 2 V for more than about 6 months and showed flat potential area between 1.9 and 1.3 V for every cycle.
The contact angle of the lead relative to the graphite at a temperature 1073 K is 138°. A novel lead-carbon material with high carbon content has been studied as possible material for positive grids of lead acid batteries.
Graphite is a generally beneficial additive because it enhances PAM utilization and often increases the cycle life of the battery. Reports on the electrochemical stability of graphite are not unanimous, but research suggests that graphite does not lower the performance of the battery.
