The invention relates to a lithium fluorocarbon battery sulfur-containing electrode and application thereof, and belongs to the technical field of lithium fluorocarbon batteries. The lithium fluorocarbon battery sulfur-containing electrode is characterized in that the lithium fluorocarbon battery sulfur-containing electrode consists of an electrolyte and a sulfur-containing solvent, wherein the electrolyte comprises one or more of inorganic anion electrolyte lithium salts and organic anion electrolyte lithium salts; and the solvent is one or more of sulfur-containing solvent esters, ethers andsulfones. The application of the lithium fluorocarbon battery sulfur-containing electrode is characterized in that the sulfur-containing electrode is applied to lithium fluorocarbon batteries; the positive active material of the lithium fluorocarbon battery is a fluorocarbon material; and the mass ratio of fluorine to carbon is 0.1 to 1.5. The electrode has preferable compatibility with a fluorocarbon positive material, the migration rate of Li+ is improved, the specific discharge capacity of the battery is obviously improved, the energy density of the battery is improved, the system energy of the battery is improved, and simultaneously, the electrode has the advantages of convenient use, wide application range and the like.
