Anode active material

The lithium host in the negative electrode: natural or synthetic graphite in almost every lithium-ion cell today, sometimes blended with a few percent of silicon to raise capacity.

Intercalation

Lithium inserting into, and leaving, the host structure of an electrode material — between graphite layers, for example — without destroying it.

Lithium plating

Lithium metal depositing on the negative-electrode surface instead of intercalating into it. It is promoted by charging at low temperature or high current.

Natural graphite

Graphite mined as flake, then milled, spheroidised and coated for use as a negative active material. It is cheaper than synthetic graphite and has slightly higher capacity, with more variability between sources.

Synthetic graphite

Graphite made by heating petroleum coke or needle coke to about 3000 °C, which gives uniform, long-lived particles at a high energy cost. It is preferred for fast-charge and long-life cells.
