A superionic conductor is a type of material that allows ions to move freely while remaining solid. This unique property combines characteristics of both solids and liquids, enabling high ionic conductivity at elevated temperatures. Superionic conductors are important for applications in batteries and fuel cells, where efficient ion transport is crucial. These materials typically consist of a solid lattice structure that contains mobile ions, such as sodium or lithium. When heated, the ions can move rapidly through the lattice, enhancing conductivity. Research into superionic conductors aims to improve energy storage technologies and develop more efficient electrolytes for various applications.
