What is superionic meaning?

Superionic refers to a state of matter where ions (electrically charged atoms or molecules) move more freely than in a solid but not as freely as in a liquid. In this state, the ions are locked in a rigid lattice structure like a solid, but they can migrate through the lattice like a liquid. This phenomenon is believed to occur at high temperatures and pressures, such as those found in the interiors of planets or stars. Superionic materials are of interest to researchers for their potential applications in energy storage, catalysis, and as novel materials for electronics and optics.
