The research team of Professor Won-ho Shin of the Department of Electronic Materials Engineering, in collaboration with the research team of Professor Kyung-seok Moon of Gyeongsang National University, has developed a core technology for all-solid-state electrolytes in next-generation batteries by creating amorphous layers at the grain boundaries of the NASICON-structured Li1.5Al0.5Ti1.5(PO4)3 (LATP) oxide-based solid electrolyte, aiming to enhance its ionic conductivity and address the risk of battery explosions, which have become a significant issue in the electric vehicle market.

The research was supported by the Basic Research Laboratory Program and the Mid-Career Research Program of the National Research Foundation of Korea, and was conducted by the master’s students, Seul-gi Shin and Sung-hyun Kang from the Department of Electronic Materials Engineering of Kwangwoon University, participated as first authors. The findings were published in the July 2024 issue of 'Composites Part B: Engineering (IF: 13.1)', a journal ranked in the top 0.84% of engineering fields worldwide.
