A Korean research team has developed a transfer printing process that enables solid electrolytes, a key component of solid-state batteries, to be fabricated as very thin, uniform and defect-free layers over large areas. The technology is expected to provide a foundation for the large-area manufacturing of high-energy-density solid-state batteries.

A research team led by principal researcher Yongku Kang and senior researcher Myung-Soo Park at the Korea Research Institute of Chemical Technology (KRICT) developed a transfer printing technology using the garnet-type oxide solid electrolyte LLZTO, in which a solid electrolyte layer is first fabricated on a separate substrate and then transferred onto an electrode.

The study was published in Advanced Functional Materials in September 2026. Post-master’s researcher Seul Gi Chu participated as the first author, while principal researcher Kang and senior researcher Park served as corresponding authors.
