Intercalant
An intercalant is a species, such as an atom, ion, or molecule, that inserts between the layers of a layered host material to form an intercalation compound. The guest species reside in the galleries between adjacent layers and can cause expansion of the interlayer spacing, charge transfer, or changes to the host’s electronic, optical, and catalytic properties.
Common hosts include graphite, transition metal dichalcogenides (for example MoS2 and WS2), layered oxides, and layered
Intercalation processes can be electrochemical, chemical, or thermal. In electrochemical systems, such as lithium-ion batteries, Li+
Synthesis methods include electrochemical intercalation, chemical intercalation by reaction with reactive species, and gas- or solution-phase
