intercalation
Inserting between layers
Intercalation is the insertion of something between existing elements.
In timekeeping, it means adding extra days or months to align a calendar with astronomical cycles—February 29th is an intercalation.
In chemistry and materials science, intercalation describes molecules or ions inserting themselves between layers of a crystalline structure: lithium intercalation in battery electrodes.
The verb is intercalate.
