Abstract
Provided are an electrolyte for a lithium secondary battery which is not oxidized/decomposed when allowed to stand at a high temperature under high voltage, so as to inhibit generation of gas to prevent expansion of the battery, thereby reducing a battery thickness increase rate, and simultaneously having an excellent storage property at a high temperature, and a lithium secondary battery including the same.
