| 摘 要： | Enabling lithium-ion batteries(LIBs)to operate in a wider temperature range, e.g., as low or high as possible or capable of both, is an urgent need and shared goal. Here we report, for the first time, a low-temperature electrolyte consisting of traditional ethylene carbonate, methyl acetate, butyronitrile solvents, and 1 M LiPF6 salt,attributed to its very low freezing point(Tf =-126.3℃) and high ion conductivity at extremely low temperatures(0.21 m S/cm at -100℃), successf...
