ADDITIVE FOR NON-AQUEOUS ELECTROLYTE SOLUTION OF ELECTRIC DOUBLE LAYER CAPACITOR, NON-AQUEOUS ELECTROLYTE SOLUTION FOR ELECTRIC DOUBLE LAYER CAPACITOR AND NON-AQUEOUS ELECTROLYTE SOLUTION ELECTRIC DOUBLE LAYER CAPACITOR

摘要

This invention relates to an additive for a non-aqueous electrolyte of an electric double layer capacitor comprising a combustion inhibiting substance releasing compound capable of releasing a combustion inhibiting substance having particularly excellent combustion inhibiting effect during combustion, and more particularly to an additive for a non-aqueous electrolyte of an electric double layer capacitor comprising a combustion inhibiting substance releasing compound which releases a combustion inhibiting substance during combustion, characterized in that the combustion inhibiting substance is a phosphine oxide compound having P-F bond and/or P-NH₂ bond in its molecule.
