New Dry-Electrode Battery Technology Could Enhance EV Range by 20%
Researchers at Ulsan National Institute of Science and Technology in South Korea have developed a dry-electrode manufacturing technique that could enhance electric vehicle (EV) driving range by about 20%. This method employs a thin lithium-metal film to mitigate early capacity loss and streamline production.
Traditional wet-chemistry processes are complex and costly due to solvent removal, while the new dry process reduces toxic solvents and manufacturing steps. The lithium-metal film improves adhesion and provides additional lithium during initial cycles, resulting in a 75% reduction in early capacity loss compared to conventional batteries. This innovation may enable existing manufacturing lines to produce more efficient batteries without added processing steps.
