Title:
NON-AQUEOUS LIQUID ELECTROLYTE, ELECTRICITY STORAGE DEVICE USING SAME, AND PHOSPHORUS COMPOUND USED THEREIN
Document Type and Number:
WIPO Patent Application WO/2016/031316
Kind Code:
A1
Abstract:
The purpose of this invention is to provide a secondary battery, the electrochemical properties of which can be improved over a wide temperature range. In this invention, in general formula (X), R10 and R20 each independently represent either a lithium atom or an organic group selected from among C1-8 alkyl groups, C2-6 alkenyl groups, C3-6 alkynyl groups, and C6-12 aryl groups. Also, X represents: a polar group (i) containing the -C(=O) group, the -P(=O) group, or the -S(=O)2 group; a polar group (ii) containing the -CN group or a C1-6 alkyl group in which fluorine atoms are substituted in place of some of the hydrogen atoms; or a polar group (iii) consisting of a four-to-seven-membered ring containing the -C(=O)-N- group or the -C(=O)-O- group. If X represents a polar group (iii) consisting of a four-to-seven-membered ring containing the -C(=O)-N- group, at least one of R10 and R20 represents a lithium atom.
