Sodium superionic conductors (SSCs) are materials that allow sodium ions to move very quickly through their structure. This property makes them promising for use in batteries, particularly in sodium-ion batteries, which are considered a more sustainable alternative to lithium-ion batteries. SSCs can operate at room temperature and have high ionic conductivity, making them efficient for energy storage. These materials typically have a crystal structure that facilitates the movement of sodium ions while remaining stable. Research into SSCs is ongoing, with scientists exploring different compositions and structures to improve their performance and make them suitable for commercial applications in energy storage and other technologies.
