Patent ID: 8703345

Claim:
An electrolyte comprising an amide compound and an ionizable lithium salt wherein the amide compound has an amine group substituted with at least one alkoxyalkyl group and comprises at least one halogen atom, represented by Formula 1: wherein R is selected from the group consisting of C 1 -C 20 halogenated alkyl groups, halogenated alkylamine groups, halogenated alkenyl groups and halogenated aryl groups, R 1 and R 2 are each independently selected from the group consisting of hydrogen, halogen, C 1 -C 20 alkyl groups, alkylamine groups, alkenyl groups and aryl groups, with the proviso that at least one of R 1 and R 2 is an alkoxyalkyl group represented by CH 3 —(CH 2 ) p —O(CH 2 ) q —, p being an integer from 0 to 8 and q being an integer from 1 to 8, and X is selected from the group consisting of silicon, oxygen, phosphorus, sulfur and hydrogen, provided that i) when X is hydrogen, m is 0, ii) when X is oxygen or sulfur, m is 1, iii) when X is nitrogen or phosphorus, m is 2, and iv) when X is silicon, m is 3.
