에너지 부문위원회 II: 차세대 지속가능 그린 에너지 구현을 위한 첨단 소재 및 융합 혁신 기술 II (1)
Abstract
Silicon is an attractive anode material for next‑generation rechargeable batteries because of its exceptional theoretical capacity (~3,579 mAh g-1). However, its practical implementation remains hindered by severe ~300 % volume change during (de)lithiation, fracture‑induced electrical isolation, and intrinsically low electronic conductivity. Rational nanostructuring has emerged as the most effective way of overcoming these obstacles. Among the various synthesis routes, chemical vapor deposition (CVD) stands out for its ability to deliver ultrahigh‑quality silicon. This presentation reviews recent advancements in CVD‑based Si anodes aimed at mitigating the fundamental limitation. Building on these advances, we will also highlight a new generation of CVD‑derived Si anode for all‑solid‑state batteries. Finally, this presentation will highlight the potential of CVD technologies as a platform for next-generation chemistries, broadening its scope beyond conventional Li-ion batteries.
