Silicon is one of the most promising anode materials for next-generation lithium-ion batteries because of its very high theoretical capacity and natural abundance, yet its practical use is limited by severe volume expansion, structural degradation, unstable solid electrolyte interphase formation, and capacity fading. Beyond these known issues, a critical but underexplored degradation feature is the Coulombic efficiency trough, a transient but universal dip in efficiency that

Our latest battery research from National Yang Ming Chiao Tung University has been widely covered by multiple international and Taiwanese media outlets. We demonstrated a new concept: 👉 Lithium batteries can operate without lithium ions in the electrolyte. By introducing a sodium-based electrolyte, our system achieves: ⚡ 167% increase in capacity 🔄 Enhanced ion transport through lattice expansion 🛡 Stable cycling performance This work challenges conventional battery design

Today, BEST Lab felt a little different — not just a place for research, but a place full of warmth. In between experiments and deadlines, the students secretly planned a birthday surprise. No grand setup, just heartfelt moments: candlelight on a cake, handwritten notes, and a simple yet genuine “Happy Birthday, Prof. Su.” Research can be demanding, but it’s people like this — thoughtful, dedicated, and kind — that make the journey truly meaningful. BEST is not just a lab. It

We are proud to announce that BEST Lab members Anlin Shaju and Aleesha K. Paulose have received the Bronze Award at the NYCU 2025 Sustainable Development Goals (SDGs) Academic Poster Competition . Their award-winning poster, titled “Interface Engineering via Anion-Driven SEI Coordination in Silver-Nucleated Lithium Metal Batteries,” was completed under the supervision of Prof. Yu-Sheng Su . This research focuses on innovative interface engineering strategies for lithium me

Silicon anodes in lithium-ion batteries suffer from severe volume change and sluggish through-plane ion transport in stacked graphene hosts. Here we report a dual-modulation strategy that couples thermal reduction with controlled H 2 O 2 etching to build a holey reduced graphene oxide (HRGO) framework around silicon. Reduction restores a continuous graphitic network while maintaining a compact interlayer structure; subsequent oxidative etching perforates the basal planes and
