    摘要： A nonaqueous electrolyte for a lithium secondary battery and a lithium secondary battery including the same are provided. In particular, the nonaqueous electrolyte comprises a compound of chemical formula 1 as an electrolyte additive: NC—(R1)n-A-(R2)m—CN   1 wherein, R1 and R2 represent, respectively, alkylene groups, n and m represent integers of 1 to 10, and A is an aromatic hydrocarbon in which the number of carbons is 5 to 9 or O. When the lithium secondary battery is kept at high voltage and temperature, the electrolyte additive reduces gas generation, thereby reducing battery swelling. Therefore, it is possible to reduce a battery thickness increment rate and to increase discharge capacity at a high temperature.

    摘要： An electrolyte for a lithium ion secondary battery includes a non-aqueous organic solvent; a lithium salt; and a phosphonitrile fluoride trimer as an additive, and a lithium ion secondary battery comprising the same. The thickness increase rate of a lithium ion secondary battery including the electrolyte is reduced even when the battery is kept at a high temperature. Thus, the thermal stability and durability of the battery are prominently improved. The durability of the battery can be further improved by including a vinylene carbonate or ethylene carbonate group compound in the electrolyte.
