A research team led by Nankai University and the Shanghai Institute of Space Power-Sources has reported a hydrofluorocarbon (HFC) electrolyte that enables lithium-metal batteries with an energy density of more than 700 Wh/kg, while maintaining operation at temperatures as low as -70 C.
The findings were published in Nature on February 25 in an article titled “Hydrofluorocarbon electrolytes for energy-dense and low-temperature batteries.”
Progress focuses on electrolyte chemistry. The researchers moved away from conventional oxygen-coordinated carbonate systems and instead developed a fluorine-coordinated electrolyte based on monofluorinated alkane solvents. Using 1,3-difluoropropane (DFP) as a core solvent, they achieved a lithium salt solution above 2 mol/L, questioning assumptions about the solubility limits of fluorinated hydrocarbons.
