COMPOSITION FOR POLYELECTROLYTES, POLYELECTROLYTES, ELECTRICAL DOUBLE LAYER CAPACITORS AND NONAQUEOUS ELECTROLYTE SECONDARY CELLS

摘要

The use of a composition for polyelectrolytes comprising a quaternary ammoni um salt (A) represented by the general formula (1) and an inonic fluid (B) brin gs about polyelectrolytes which retain excellent characteristics inherent in th e ionic fluid and exhibit excellent safety and electric conductivity and wide potential windows: (1) wherein R1 to R3 are each independently alkyl having 1 to 5 carbon atoms or a substituent having a reactive unsaturated bond, or an y two of R1 to R3 may form a ring; R4 is methyl, ethyl, or a substituent havin g a reactive unsaturated bond, with the proviso that at least one of R1 to R4 is a substituent having a reactive unsaturated bond; X is a monovalent anion; m is an integer of 1 to 8; and n is an integer of 1 to 4.
