Intercalation Compound
Intercalation compounds are produced by the insertion of an atomic or molecular species into a host lattice. Many common solid materials possess this property: graphite (structure shown in Fig. 10), MoO 3, H x MoO 3 (a hydrogen bronze), V 2 O 5, Zr(HPO 4) 2, FeOCl, and many clays to mention but a few.The reactions that lead to the intercalated substances are classified as …

The importance of graphene stacking sequence in the Li-intercalation
The variation in Li-intercalation performance is assigned to the evolution of graphene stacking sequences. Intercalation begins during the early stages of graphitization with the appearance of AB pairs (AB stacking sequence), indicating that the mechanism starts even before the formation of the true graphitic structure.

Intercalation pseudocapacitance in electrochemical energy storage
For the mechanism of intercalation storage controlled by diffusion, which accords with the typical charge-storage behavior of battery materials, the Faradaic reaction takes place in the bulk phase with the deep diffusion of ions into interlayer gaps (or van der Waals gaps) [6, 19]. If intercalation is fast enough in kinetics, pseudocapacitance ...

Intercalation (chemistry)
One proposed mechanism of intercalation is as follows: in aqueous isotonic solution, the cationic intercalator is attracted electrostatically to the polyanionic DNA. The ligand displaces a sodium and/or magnesium cation that always surround DNA (to balance its charge) and forms a weak electrostatic bond with the outer surface of DNA.
