How ions flow like a liquid through a solid crystal
Researchers have identified the physical mechanism behind superionic conduction, where ions move through a solid crystal as if they were in a liquid state. This discovery provides a theoretical framework that could accelerate the development of more efficient solid-state batteries.
Why it matters
Advancements in superionic conduction are critical for creating safer, higher-capacity solid-state batteries, which are essential for the future of electric vehicles and energy storage.

Add as preferred source The trajectories of carrier particles in the superionic conducting regime in our model: The colors of the trajectory distinguish individual particles. The carrier particles move in a liquid-like manner through the interstitial spaces between the host particles forming the crystalline framework, clearly demonstrating their rapid transport. Credit: Takeshi Kawasaki A research team led by the University of Osaka, working with the National Institute of Advanced Industrial Science and Technology (AIST), RIKEN and the Institute of Science Tokyo, has uncovered a fundamental mechanism behind superionic conduction, in which ions move rapidly through a solid while its crystalline framework remains intact.
