摘要： Disclosed is a nonaqueous electrolyte for a lithium-ion secondary battery that contains an addictive for preventing destruction of a solid electrolyte interface (SEI) layer and hence decomposition of the electrolyte that may cause generation of a gas, thereby preventing swelling of the battery caused by the gas generated from the inside of the battery at a high temperature. More specifically, the present invention provides an electrolyte that includes, as an additive, 2-sulfobenzoic acid cyclic anhydride represented by the formula 1: The electrolyte contains the additive in an amount of 0.1 to 10.0 wt. %.

摘要： A lithium secondary battery exhibiting good mechanical properties and using a thin negative current collector is provided. The lithium secondary battery includes a positive electrode formed by coating lithium metal oxides on a positive current collector and a negative electrode formed by coating carbonaceous materials or SnO2 on a negative current collector. The negative current collector is made of a Cu-based alloy foil with a thickness of 20 μm or less and the Cu-based alloy foil includes at least one material selected from the group consisting of nickel, titanium, magnesium, tin, zinc, boron, chromium, manganese, silicone, cobalt, iron, vanadium, aluminum, zirconium, niobium, phosphorous, bismuth, lead, silver and misch metal. The lithium secondary battery further includes a separator interposed between the positive and negative electrodes and an electrolyte into which the positive and negative electrodes and the separator are immersed.
