Abstract
Non-aqueous electrolytic solutions for capacitors which release a little gas, have excellent potential window of electrochemical stability and enable capacitors to show excellent charging/discharging cycle properties and safety performance, and capacitors containing such non-aqueous electrolytic solutions. The non-aqueous electrolytic solution for capacitors comprises an electrolytic solution containing at least one cyclic carbonic ester selected from specified compounds and an electrolyte.
