The process of making natural graphite suitable for batteries involves several steps. After mining, the graphite needs to be purified to reach a carbon content of over 99.95%. Techniques like acid leaching or caustic purification help remove impurities, though some methods such as using hydrofluoric acid, raise environmental and safety concerns.

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.
