Intercalation

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

Lithium-ion battery

A rechargeable cell in which lithium ions shuttle between two intercalation electrodes, typically graphite and a lithium metal oxide, through a non-aqueous electrolyte. Commercialised in 1991, it dominates portable electronics, electric vehicles and new grid storage.

Lithium-metal battery

A rechargeable cell whose negative electrode is lithium metal rather than a host material. It promises much higher energy density than lithium-ion, but lithium deposits unevenly on charge, so dendrites and short life have kept it from the mass market.
