Korean Institute develops transfer printing for solid-state battery electrolytes

A research team at the Korea Research Institute of Chemical Technology developed a transfer printing process for solid electrolytes, a key component of solid-state batteries. This technology allows for the fabrication of very thin, uniform, and defect-free solid electrolyte layers over large areas using garnet-type oxide LLZTO. The method overcomes challenges associated with conventional fabrication techniques, which often result in overly thick or non-uniform layers.

The ability to manufacture solid electrolytes in large areas provides a foundation for high-energy-density solid-state battery production. Solid-state batteries offer the potential to reduce fire risks and increase energy density compared to traditional liquid electrolyte batteries. This breakthrough addresses manufacturing limitations that previously hindered the commercial viability of these batteries.
