ELECTRIC DOUBLE-LAYER CAPACITOR AND ELECTROLYTE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor electrolyte having a high specific conductivity and the electric double-layer capacitor which behaves a low equivalent series resistance and has high reliability, using the electrolyte. SOLUTION: The electrolyte for the electric double-layer capacitor consists of an electrolyte (A) made of an amidinum cation (a1) and anion (a2), and a non-aqueous solvent (B) whose viscosity is 0.1-1.3 mPa.s at 25°C.
