Abstract

Official abstract text for this publication.

The disclosure aims to provide an electrolytic solution with which an electrochemical device exhibiting excellent battery characteristics even with a negative electrode containing an alkali metal-containing material can be obtained. Provided is an electrolytic solution which is for use in a battery including a negative electrode containing an alkali metal-containing material, the electrolytic solution containing a solvent, the solvent including a compound (1) represented by the following formula (1):wherein R101 and R102 are each independently a C1-C3 non-fluorinated alkyl group, R103 to R106 are each independently a hydrogen atom or a halogen atom, and at least one selected from R103 to R106 is a halogen atom.

First claim

1 . An electrolytic solution which is for use in a battery comprising a negative electrode containing an alkali metal-containing material, the electrolytic solution comprising a solvent, the solvent comprising a compound (1) represented by the following formula (1): wherein R 101 and R 102 are each independently a C1-C3 non-fluorinated alkyl group, R 103 to R 106 are each independently a hydrogen atom or a halogen atom, and at least one selected from R 103 to R 106 is a halogen atom. 2 . The electrolytic solution according to claim 1 , wherein the compound (1) includes at least one selected from the group consisting of compounds represented by the following formulas: 3 . The electrolytic solution according to claim 1 , wherein the compound (1) is contained in an amount of 0.01 to 80% by volume relative to the solvent. 4 . The electrolytic solution according to claim 1 , wherein the alkali metal includes at least one selected from the group consisting of lithium, sodium, and potassium. 5 . An electrochemical device comprising the electrolytic solution according to claim 1 . 6 . A secondary battery comprising the electrolytic solution according to claim 1 . 7 . A lithium-ion secondary battery comprising the electrolytic solution according to claim 1 .
