Sejong University said Tuesday that a research team had developed a next-generation silicon anode that enables faster charging and longer battery life, a potential advance for electric vehicles and energy storage systems. The team, led by Yang Hyeon-woo and Kim Sun-jae of the department of nanotechnology and advanced materials engineering, developed a freestanding silicon anode that maintains high performance without conventional components like current collectors, binders or conductive additives. The findings were published online April 6 in Advanced Fiber Materials, an international journal with an impact factor of 21.3 — a measure of how often its research is cited — placing it among the more influential publications in its field, according to the university. The researchers at Sejong University introduced a novel electrode architecture that uses carbon nanofibers as a foundational framework, a design intended to overcome the historic fragility of silicon-based components. By engineering precise hydrolysis and condensation reactions directly onto the surface of each fiber, the te
