Title:
ELECTROLYTE SOLUTION FOR POWER STORAGE DEVICE, AND IONIC LIQUID
Document Type and Number:
WIPO Patent Application WO/2021/176920
Kind Code:
A1
Abstract:
This electrolyte solution for a power storage device contains, as a primary component, an ionic liquid which is represented by formula (1) and is constituted from a tricyanofluoroborate anion and a quaternary ammonium ion, can be used as a 100% ionic liquid electrolyte solution, and yields a power storage device having excellent rate characteristics and cycle characteristics. (In the formula, each of R1-R4 independently represents an alkyl group having 1-4 carbon atoms or an alkoxyalkyl group that is represented by -(CH2)n-OR where R represents an alkyl group having 1-4 carbon atoms, and n represents an integer of 1 or 2. Moreover, any one of R1 to R4 is the alkoxyalkyl group, and any two of R1 to R4 may bond to each other to form a ring together with a nitrogen atom.)
