    摘要: An organic electrolytic solution for a lithium-sulfur battery that can improve discharge capacity and cycle life of the battery, and a lithium-sulfur battery using the organic electrolytic solution are provided. The electrolytic solution includes a lithium salt, an organic solvent, and further a phosphine sulfide-based compound represented by formula (I) below: wherein R1, R2 and R3 are the same or different from each other, and each represents one selected from the group consisting of a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C1-C30 alkoxy group and a substituted or unsubstituted C8-C30 aralkenyl group. The electrolytic solution including the phosphine sulfide-based compound represented by Formula (I) can suppress production of lithium sulfides so that a reduction in battery capacity can be prevented.

    摘要: An organic electrolytic solution including a lithium salt, an organic solvent, and a compound represented by the formula and a lithium battery employing the organic electrolytic solution. Groups Z1 and Z2 are each, independently, a cyano group, an isocyano group, a substituted or unsubstituted dicyanoethylphosphino group, or a substituted or unsubstituted dialkoxyphosphoryloxy group. Groups R1 through R4 are described fully in the Description. The organic electrolyte solution inhibits decomposition of an electrolytic solution and elution or precipitation of metal ions, and thus the lithium battery including the organic electrolytic solution has excellent cycle characteristics and lifetime characteristics.

    摘要: A lithium-sulfur battery includes a cathode, a lithium metal anode, and a separator interposed between the cathode and the anode. The separator contains less than two fluorine atoms per carbon atom to enable a protective layer to form on a surface of the lithium metal anode. The lithium-sulfur battery forms a uniform and dense LiF protective layer on the surface of the lithium metal and stabilizes the lithium metal during its operation. The lithium-sulfur battery prevents the formation of lithium dendrites and inhibits the decomposition of an electrolytic solution to provide improved cycle characteristics and excellent charging/discharging efficiency. In addition, the lithium-sulfur battery blocks the reaction of polysulfide with the surface of lithium metal to prevent a reduction of the lifetime of the battery.

    摘要: A positive electrode which has a positive active material layer formed on a conductive substrate and a polymer film coated on the positive active material layer, wherein the positive active material layer includes a positive active material, pores of which are filled with a polymeric material containing a nonaqueous electrolyte, and the polymer film, and the polymer film formed of the polymeric material containing the nonaqueous electrolyte. The polymeric material is formed by polymerization of a composition comprising a monomer and the nonaqueous electrolyte. The monomer includes 1 to 6 functional groups per molecule, and the functional groups are selected from the group consisting of vinyl, allyl, acryl, methacryl and epoxy group. Since the lithium-sulfur battery using the positive electrode increases degree of the positive active material utilization, the cycle life characteristics and capacity of the battery can be improved, and swelling of the positive electrode of the lithium-sulfur battery can be reduced.
