The present invention relates to an electrolyte for a secondary battery and a secondary battery comprising the same, and more particularly, to a battery comprising an electrolytic salt, an organic solvent and an additive, wherein the additive contains a compound having an N-Si bond and a compound having an O- And at least one compound selected from the group consisting of compounds represented by the following general formulas. Since the electrolyte for the secondary battery includes an additive containing specific chemical bonds, it is possible to improve the efficiency and lifetime characteristics of the multivalent metal secondary battery by inhibiting film formation on the surface of the multivalent metal. |
