As demand rises for fast-charging and high-energy lithium-ion batteries, thick SiO x -based anodes still face slow ion transport and mechanical degradation. Researchers led by Prof. Hongkyung Lee and Prof. Yong Min Lee now report a scalable solution based on a perforated Cu (pCu) current collector, which induces a regularly arranged micropore (RAM) structure. This simple yet powerful design enhances ion diffusion, mechanical stability, and overall electrochemical performance in SiO x /artificial graphite (AG) electrodes.
