6 FAQs about [Graphite modified lead-acid battery]
Is graphite better than gold for lead acid batteries?
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.
Can graphite sheet be used for cathode current collector of lead acid battery?
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.
