  "textContent": "An electrolyte composition for lithium secondary batteries includes a lithium salt and an organic solvent. The organic solvent includes an aromatic solvent with fluorinated toluene derivatives (such as 2,3-difluorotoluene) and an ether solvent. The lithium salt can include compounds like Li(CF3SO2)2N, Li(SO2F)2N, LiPF6, and others. The aromatic solvent is present at about 30-90 vol % of the electrolyte, and the lithium salt molarity ranges from 0.1 to 3.0 M. This composition improves battery performance by enhancing stability, conductivity, and compatibility with lithium metal or lithium-ion electrodes, making it suitable for high-energy-density applications in lithium secondary batteries.",
