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.
Storage Capability: Graphite’s layered structure allows lithium batteries to intercalate (slide between layers). This means that lithium ions from the battery’s cathode move to the graphite anode and nestle between its layers when the battery charges. During discharge, these ions move back to the cathode, releasing energy in the process.
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 for batteries currently accounts to only 5 percent of the global demand. Graphite comes in two forms: natural graphite from mines and synthetic graphite from petroleum coke. Both types are used for Li-ion anode material with 55 percent gravitating towards synthetic and the balance to natural graphite.
The effects of various graphite on electrochemical performance were investigated using SEM, mercury porosimetry, and TGA/DSC to correlate the function of graphite on the positive active mass utilization of the lead-acid battery.
