A research team led by Professor Li Shukui and Associate Researcher Bian Juncao from the Faculty of Materials Science has made a major breakthrough in key materials for all-solid-state batteries. The team successfully synthesized a novel lithium thioborate (LiBS2) solid-state electrolyte and uncovered a new mechanism where dynamic “Li–S” coordination coupling enhances lithium-ion conduction. The findings have been published under the title “Dynamic Li–S Coordination Boosted Superionic Conduction in Cubic LiBS2 Solid Electrolyte” in Advanced Functional Materials, a top international journal. The Longgang-based university is the primary completing institution for this study. The co-corresponding authors include Professor Li Shukui, Associate Researcher Bian Juncao, Professor Wang Liping from the Southern University of Science and Technology (SUSTech), Associate Professor Deng Bei from Shantou University, and Associate Profile Researcher Wang Pei from the Institute of Solid State Physics, Chinese Academy of Sciences.
