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.
The 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.
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.
Graphite and lead are both materials with historical significance but vastly different properties and health implications. Graphite is a safe, versatile form of carbon, while lead is a toxic metal with limited modern applications due to its health hazards. Carbon Material. Graphite is commonly used in pencil leads for writing. Shielding Radiation.
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.
