A Korean research team has developed a technology that enhances the lifespan and stability of all-solid-state batteries by using a rubber-like, elastic ion-conductive material. The research was published in Energy Storage Materials.
Dr. Dong Wook Kim and his research team at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with Professor Seong-Ju Hwang's team at Yonsei University and Professor Ho Seok Park's team at Sungkyunkwan University, developed a technology that incorporates an "elastic ion-conductive polymer" into sulfide-based all-solid-state batteries to reduce cracking and interfacial degradation generated during charge-discharge cycling and thereby improve battery durability.
As electric vehicle adoption accelerates worldwide, all-solid-state batteries are attracting significant attention as next-generation energy storage systems. Unlike conventional lithium-ion batteries that use flammable liquid electrolytes, all-solid-state batteries employ solid electrolytes, offering superior safety.
