STM of CrCl3-graphite intercalation compounds: …

Due to the existence of Daumas-Herold domains with one and two graphite layers on the guest layer closest to the surface, which exhibit different STM images, the first direct evidence is given for the existence of small intercalated islands. The island shape is shown to be very complicated.

Expandable Graphite flakes | Graphite intercalation ...

Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. This material is manufactured by treating flake graphite with various intercalation reagents that migrate between the graphene layers in a graphite crystal and remain as stable species.

Stable and High‐Power Calcium‐Ion Batteries Enabled …

It is found that the calcium ions are intercalated into graphite galleries with a staging process. The intercalation mechanisms of the “calciated” graphite are elucidated using a suite of techniques including synchrotron in situ X‐ray diffraction, nuclear magnetic resonance, and first‐principles calculations.
