The graphite used in battery anodes is typically a form of high-grade purified flake graphite, which has a layered structure that allows for the intercalation of lithium ions during charging and discharging cycles. Since graphite is naturally hydrophobic, flotation beneficiation is the most utilized enrichment technique for upgrading.
