摘要： Disclosed is a lithium secondary battery comprising a cathode, an anode, an electrolyte and a separator, wherein the anode comprises an anode active material having a specific surface area of 3 m2/g or less, and the electrolyte comprises 0.1˜6 parts by weight of a propane sultone-based compound based on 100 parts by weight of the electrolyte. The lithium secondary battery solves the problem of performance degradation caused by the use of an increased amount of a propane sultone-based compound required to form a SEI film on the surface of an anode upon the first charge cycle. Also, the lithium secondary battery can provide improved cycle characteristics and high-temperature storage characteristics.

摘要： Disclosed is an electrolyte for batteries, comprising: (a) an electrolyte salt; (b) an organic solvent; (c) a first compound having an oxidation initiation voltage (vs. Li/Li+) higher than the operating voltage of a cathode; and (d) a second reversible compound having an oxidation initiation voltage higher than the operating voltage of the cathode, but lower than the oxidation initiation voltage of the first compound. Also disclosed is a lithium secondary battery comprising said electrolyte. In the lithium secondary battery, two compounds having different safety improvement actions at a voltage higher than the operating voltage of the cathode are used in combination as electrolyte components. Thus, the safety of the secondary battery in an overcharged state can be ensured, and at the same time, the deterioration of the battery can be prevented from occurring when it is repeatedly cycled, continuously charged and stored at high temperature for a long time.
