Title:
NOVEL BATTERY SYSTEMS BASED ON TWO-ADDITIVE ELECTROLYTE SYSTEMS
Abstract:
Improved battery systems have been developed for lithium-ion based batteries. The improved battery systems consist of two-additive mixtures in an electrolyte solvent that is a carbonate solvent, an organic solvent, a non-aqueous solvent, and/or methyl acetate. The positive electrode of the improved battery systems may be formed from lithium nickel manganese cobalt compounds, and the negative electrode of the improved battery system may be formed from natural or artificial graphite.

Abstracts:
Provided are: a nonaqueous electrolytic solution that is capable of having improved electrochemical characteristics in a wide temperature range, that has an electrolyte salt dissolved in a nonaqueous solvent, and that is characterized by containing an (2-oxo-1,3-dioxolan-4-yl)oxy compound represented by general formula (I); an electricity storage device; and a novel (2-oxo-1,3-dioxolan-4-yl)oxy compound. (In the formula, R1 represents a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, -OC(=O)-R4, -OS(=O)2-R5, or -OP(=O)(-R6)-R7. R2 and R3 each independently represent a hydrogen atom, a halogen atom, or an alkyl group, and n represents an integer of 1-3. R4 represents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, or an alkoxycarbonyl group. R5 represents a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, or an alkoxy group. R6 and R7 each independently represent a halogen atom, an alkoxy group, or an aryloxy group. In the case where n is 1, L1 represents -C(=O)-R4, -S(=O)2-R5 or -P(=O)(-R6)-R7. In the case where n is 2, L1 represents -C(=O)C(=O)-, -S(=O)2-, or -P(=O)(-R6)-. In the case where n is 3, L1 represents -P(=O)(-)2.)
