New silicon anodes boost lithium batteries’ energy density by 250% for future EVs
SMRTR summary
German scientists developed new fiber-based silicon anodes that boost lithium-ion battery energy density by 250% compared to conventional graphite anodes. The breakthrough uses flexible, electrically conductive nonwoven fibers that accommodate silicon's expansion during charging, preventing the cracking and failure that has limited silicon's use in batteries. This technology could enable lighter electric vehicle battery packs with longer driving ranges.
