Abstract:
1. An electrolyte, comprising: (a) an eutectic mixture of an alkoxy alkyl group-containing amide compound expressed by the following chemistry figure 1 or 2 and an ionizable lithium salt; and (b) a carbonate-based compound, wherein R, R X is any one selected from the group consisting of silicon, oxygen, nitrogen, phosphorus, sulfur and hydrogen, and i) m is 0 (zero) when X is hydrogen, ii) m is 1 when X is oxygen or sulfur, iii) m is 2 when X is nitrogen or phosphorus, and iv) m is 3 when X is silicon; wherein R is hydrogen, or any one selected from the group consisting of an alkyl group, alkylamine group, alkenyl group, aryl group and allyl group having 1 to 20 carbons, and R X is any one selected from the group consisting of silicon, oxygen, nitrogen, phosphorus and sulfur, and i) m is 0 (zero) when X is oxygen or sulfur, ii) m is 1 when X is nitrogen or phosphorus, and iii) m is 2 when X is silicon, and n is an integer of 1 to 10; and wherein the eutectic mixture comprises the alkoxy alkyl group-containing amide compound and the lithium salt at a mole ratio of 1-8: 1.
