The Korea Research Institute of Standards and Science (KRISS) has developed a materials technology that reduces the production costs of all-solid-state batteries to one-tenth of conventional levels by addressing lithium evaporation issues during high-temperature processing. Utilizing Li-Al-O-based multifunctional compounds, the technology achieves over 98.2% density and more than double the ionic conductivity, enabling the production of large-area solid electrolyte membranes with a 99.9% yield. This advancement is poised to enhance domestic production of next-generation battery materials in South Korea.
