摘要： An organic electrolytic solution and a rechargeable lithium battery comprising the same is provided. The organic electrolytic solution contains a lithium salt and an organic solvent mixture. The organic solvent mixture is comprised of a solvent with high permittivity, a solvent with a low boiling point, and a cyclic organic compound having at least an oxy-carbonyl group and having a ring structure of 6 units or more. The organic electrolytic solution helps to increase reduction decomposition stability in the lithium battery using the same. As a result, the irreversible capacity of the lithium battery at a first cycle decreases and charge/discharge efficiency and lifespan of the lithium battery increases. In addition, the battery thickness is maintained within a specific range at room temperature after formation and standard charging, which improves the reliability of the lithium battery.

摘要： An organic electrolytic solution and a lithium battery employing the same are provided. The organic electrolytic solution includes: a lithium salt; an organic solvent containing a high dielectric constant solvent and a low boiling point solvent; and a carbonate or oxalate derivative having at least one substituted or unsubstituted cyano group. The organic electrolytic solution and the lithium battery employing the same have improved reductive decomposition stability, thereby decreasing an irreversible capacity after a first cycle and improving the charge/discharge efficiency and lifespan of the battery. The lithium battery has non-varying chemical properties at room temperature and a uniform thickness after standard charging, and thus has high reliability.

摘要： An organic electrolytic solution containing an organic solvent and a compound that contains an anionic polymerization monomer with an added component capable of being chelated with a lithium metal cation. A lithium battery may utilize the organic electrolytic solution. The lithium battery may have improved stability to reductive decomposition, reduced first cycle irreversible capacity, and improved charging/discharging efficiency and lifespan. Moreover, reliability of the battery may be improved because the battery, after formation and standard charging at room temperature, may not swell beyond a predetermined thickness. Even when the lithium battery swells significantly at a high temperature, the capacity of the lithium battery may be high enough for practical applications due to its recovery capacity.

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.
