A research team from Shanghai and Tianjin institutes has developed an innovative hydrofluorocarbon-based lithium battery electrolyte that can operate efficiently from extreme cold (-70°C) to room temperature. According to the researchers, batteries made with this new electrolyte have over twice the energy density of those made with conventional electrolytes when operating at room temperature. The breakthrough addresses a major limitation of current lithium batteries, which struggle in cold conditions and have limited energy storage capacity. Li Yong, a researcher at the Shanghai Institute of Space Power-Sources (SISP), stated that this technology could increase the room temperature energy storage capacity of lithium batteries by two to three times. The hydrofluorocarbon electrolytes provide what researchers describe as a promising pathway to break the power and energy density ceiling of batteries, potentially revolutionizing electric vehicle performance and cold-weather operation.
