Abstract

The present invention relates to an organic electrolytic solution, comprising: - a first lithium salt, - an organic solvent, and - a tetraoxide-tetraoxa-dithiaspiroalkane derivative represented by Formula 1 below: <img class="EMIRef" id="461544977-ia01" /> wherein, in Formula 1, each of A1, A2, A3, and A4 is independently a covalent bond, a substituted or unsubstituted C1-C5 alkylene group, a carbonyl group, or a sulfinyl group, wherein both A1 and A2 are not a covalent bond and both A3 and A4 are not a covalent bond. The specific compound 3,3,9,9-tetraoxide-2,4,8,10-tetraoxa-3,9-dithiaspiro[5.5]undecane is disclosed as an example. The present invention also relates to a lithium battery comprising such an electrolytic solution.
