IonicLayered

IonicLayered (often written "ioniclayered") is a descriptive term applied to a class of materials composed of stacked ionic sheets or layers bound together by electrostatic interactions and weaker van der Waals forces. These layered ionic compounds display structural anisotropy, with strong in-plane bonding and comparatively weaker interlayer interactions that can enable ion mobility, intercalation, and exfoliation into two-dimensional fragments.

Characteristics commonly associated with ionic layered materials include directional electrical and thermal conductivity, tunable interlayer spacing, and the capacity for guest species insertion. Their crystal chemistries span oxides, halides, chalcogenides with mixed ionic-covalent character, and various layered perovskites or transition metal oxide families. Composition and stacking order strongly influence electronic structure, optical properties, and ionic transport.

Applications draw on ion transport and intercalation behavior, making these materials relevant to rechargeable battery electrodes, solid electrolytes, ion sieving membranes, sensors, and emerging optoelectronic devices. Research also explores their potential in catalysis and as precursors for two-dimensional materials with distinct surface chemistries.

Synthesis routes include solid-state reaction, chemical vapor deposition, solution-based growth, and mechanical or chemical exfoliation. Contemporary studies emphasize structure–property relationships, defect engineering, computational screening for new compositions, and scalable synthesis methods. The term "ioniclayered" is used broadly in literature and industry to denote the layered ionic motif rather than a single compound or trademark.
