Definition

The reversible process of inserting ions or atoms into the structural lattice of a solid material, commonly used in battery-like electrode systems.

Derived from the Latin 'intercalare', meaning to insert or proclaim a day to be inserted into the calendar. It entered scientific English to describe the act of inserting objects or layers between others.
