▎ 摘　　要

NOVELTY - Wide temperature range electrolyte comprises methyl butyrate or its derivatives and propylene carbonate are used as mixed solvent, and lithium salt is used as solute. The concentration of lithium salt is 0.1-10mol/L. The liquid is kept in wide temperature range of (-)110-150 degrees C. USE - Wide temperature range electrolyte for lithium-carbon fluoride batteries. ADVANTAGE - The wide temperature range electrolyte has excellent specific capacity in wide temperature range, multiplies power performance. The wide temperature range electrolyte exhibits a higher ion conductivity and stability.
