AI Insight
Researchers from Sogang University and the Institute for Molecular Science have discovered that lithium ions can move up to 10,000 times faster in organic ionic plastic crystals when molecular cages surrounding them temporarily open. The study provides molecular-level insights into ion transport mechanisms within these materials, which are being developed as solid electrolytes for batteries. This breakthrough explains how lithium ions achieve sudden bursts of high mobility despite being constrained in crystalline structures.
Why it matters
Understanding how lithium ions move through solid electrolytes is critical for developing safer, more efficient next-generation batteries. This research could accelerate the design of organic ionic plastic crystals with optimized ion transport properties, potentially leading to solid-state batteries that avoid the safety risks of liquid electrolytes while maintaining high performance.
Understand the Science
An international collaborative research group led by Professor Bong June Sung of the Department of Chemistry at Sogang University and Professor Shinji Saito of the Institute for Molecular Science (IMS), National Institutes of Natural Sciences (NINS), and the Graduate University for Advanced Studies, SOKENDAI, has elucidated, at the molecular level, how lithium ions move within organic ionic plastic crystals (OIPCs)—which are attracting attention as solid electrolytes for next-generation batteries.
