Title: NON-AQUEOUS ELECTROLYTE SOLUTION AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Abstract:
The present invention relates to a non-aqueous electrolyte solution and a lithium secondary battery comprising same, the non-aqueous electrolyte solution comprising: a non-aqueous organic solvent; a lithium salt; and an oligomer represented by chemical formula 1 disclosed in the present specification. The non-aqueous electrolyte solution, according to one embodiment of the present invention, may enable the reduction of gases such as CO or CO2 generated inside the secondary battery during high-temperature storage, and thus may further enhance the high-temperature stability of the lithium secondary battery.
