Customer ServiceThe effects of expanded and not expanded (natural flake) graphite additives were evaluated on the discharge utilization of the positive active material (PAM) in the lead-acid battery. Graphite powders were added to the paste at 2.20 vol. % and tested in model 2V battery cells under a wide range of discharge currents from 8C to C/20.
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.
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.
