Cathode

The electrode where reduction happens: the positive electrode on discharge, the negative one on charge. In industry usage, “cathode” means the positive electrode and its material, whatever the cell is doing.

Graphite

Layered carbon, the negative active material of nearly all lithium-ion cells. Lithium intercalates between its layers up to LiC₆, a theoretical 372 mAh/g, at a potential about 0.1 V above lithium metal.

Negative electrode

The electrode at the lower potential, usually graphite on copper foil in a lithium-ion cell. It holds the lithium when the cell is charged and releases it on discharge, and industry calls it the anode.

Oxidation

Loss of electrons by a species. On discharge the negative electrode is oxidised as lithium leaves it as Li⁺, which is why that electrode is called the anode.
