Anode Material

Graphite is currently used as the active anode material in about 90 % of all lithium-ion batteries. The remaining 10% usually come from amorphous carbon, lithium titanate or silicon. Therefore, graphite dominates the market for anode materials. The high surface area and layered crystal structure which are features of graphite makes it suitable for use as an anode material into which the lithium ions are intercalated, i.e. “sandwiched” between layers of graphite.
