  "textContent": "A research team in China has developed an electrolyte using monofluorinated hydrofluorocarbon (HFC) solvents capable of achieving energy densities higher than 700 Wh kg−1 at room temperature and about 400 Wh kg−1 at −50 °C, a significant improvement over current technologies. Their work, recently published in Nature, has potential applications in electric vehicles, aerospace, and grid storage for operation in extreme climates.",
