Electrolytic solution for aluminum electrolytic capacitors, and aluminum electrolytic capacitor using the same |
摘要 |
The present invention provides an electrolytic solution for aluminum electrolytic capacitors which has a high sparking voltage while maintaining its specific conductivity at 30° C. of 4 to 25 mS/cm and which has no possibility of corroding capacitor elements, and an aluminum electrolytic capacitor using the same. The electrolytic solution of the present invention is characterized as being an electrolytic solution containing an electrolyte (C) composed of an alkyl phosphate anion (A) represented by formula (1) or (2) given below and a cation (B), and an organic solvent (D), wherein the content of phosphoric acid in the electrolytic solution is 1% by weight or less: wherein R1 is an alkyl group having 1 to 10 carbon atoms and R2 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms. |
