Reaction, generally reversible, that involves the penetration
of a host material by guest
species without causing a major structural modification of the host.
- Intercalation can refer to the insertion of a guest species into a one-, two- or three-dimensional host structure.
- The guest species is not distributed randomly but occupies positions
predetermined by the structure of the host material.
- Examples of intercalation reactions are the insertion of lithium into layered
(0 ≤ x ≤ 1)]
and of potassium into the layers of graphite
