Chinese lithium battery electrolyte could double EV range and run in extreme cold

Chinese scientists have created an all-weather electrolyte that could improve lithium batteries, allowing them to operate more efficiently at room temperature and in extreme environments. The research team from Shanghai and Tianjin said batteries made using the hydrofluorocarbon-based electrolyte had more than double the energy density of those made with traditional electrolytes when operating at room temperature. They said the batteries could also operate efficiently at minus 70 degrees Celsius...
