Following the keynote by Prof. Ungyu Paik, the QAMSS community welcomed Prof. Taeseup Song, Associate Professor at the Department of Energy Engineering, Hanyang University (South Korea), for the second invited talk of the day. Prof. Song’s lecture focused on cutting-edge strategies in the development of all-solid-state batteries (ASSBs) — a next-generation energy storage solution poised to revolutionize safety and performance in battery technology.
Titled “Interface Engineering for All-Solid-State Batteries”, the talk addressed one of the critical bottlenecks in the practical deployment of ASSBs: interfacial instability between lithium metal anodes and sulfide-based solid electrolytes. Prof. Song explored how contact loss and chemical degradation at the electrode–electrolyte interface can lead to lithium dendrite growth and rapid performance deterioration.
He then introduced his team's recent advances in electrochemical and mechanical interface stabilization, which significantly reduce dendrite formation and suppress unwanted side reactions. These improvements translate into enhanced cyclability and safety, bringing ASSBs closer to commercial viability.
Prof. Song’s research integrates materials design with practical engineering solutions and has drawn recognition from both academic and industrial communities. He has collaborated with major global companies including Samsung SDI, LG Chem, and SK Hynix, and has received multiple awards for his contributions to the field.
The lecture was part of an ongoing initiative to strengthen international research collaboration in energy technologies between Cambridge and South Korea.
