ELECTROLYTE AND SECONDARY BATTERY WITH THE SAME

摘要

The present invention relates to an electrolyte and a lithium secondary battery comprising the same. The electrolyte comprising a compound represented by chemical formula 1 improves battery properties of a lithium secondary battery, and particularly high-temperature storage performance of the battery operated at a high voltage, inhibits the oxidation of the electrolyte, and has effects in improving the performance of the battery by stabilizing an active site of a surface of a positive electrode.
