In the realm of materials science, the exploration of materials with exceptional ionic conductivity has garnered immense attention due to their potential applications in various energy conversion and storage technologies. Among these materials, Dion Jacobson layered perovskites have emerged as promising candidates for oxide ion conduction, paving the way for groundbreaking advancements in solid-state electrolytes, fuel cells, and other electrochemical devices.

Delving into the Structural Uniqueness of Dion Jacobson Perovskites

Dion Jacobson layered perovskites possess a distinct structural arrangement characterized by alternating layers of perovskite-like blocks and alkali metal ions. This unique architecture provides a highly anisotropic pathway for oxide ion transport, enabling efficient conduction along the layers. The presence of large alkali metal ions, such as potassium or rubidium, creates spacious interstitial sites within the perovskite layers, facilitating the migration of oxide ions.
