Problems solved by technology

[0005] However, when the above-mentioned dibasic acids or salts having side chains are used as the solute of the electrolytic solution for driving, in the case of only these dibasic acids or salts having side chains, for example, due to only one carboxyl group There are side chains, resulting in insufficient heat resistance at high temperatures. In addition, the longer the use time, the more the esterification reaction between the carboxyl group in the solute and alcohol such as ethylene glycol will be carried out, which will greatly reduce the conductivity at high temperature. , thus causing significant degradation to the performance of electrolytic capacitors

Abstract

A driving electrolyte containing a solvent, a solute containing the following compounds represented by General Formulae (1) and (2) prepared by synthesis, and a nitro compound, (wherein, each of R<1 >and R<2 >is independently an alkyl group; each of M<1 >and M<2 >is a functional group selected from the group consisting of a hydrogen atom, an ammonium group and an amine group; and n is an integer of 0 to 14), (wherein, R<3 >is an alkyl group; R<4 >is a functional group selected from the group consisting of a hydrogen atom, a methyl group and an ethyl group; M<3 >is a functional group selected from the group consisting of a hydrogen atom, an ammonium group and an amine group; and m is an integer of 0 to 14).

Description

technical field [0001] The present invention relates to an electrolytic solution for driving and an electrolytic capacitor using the electrolytic solution. technical background [0002] Among conventional driving electrolytes used for electrolytic capacitors, ethylene glycol is used as a solvent, and organic carboxylic acids such as azelaic acid, sebacic acid, and adipic acid or their salts are used as solutes. liquid is known to the public. This non-aqueous driving electrolyte has been used for high-voltage capacitors for a long time because it maintains good chemical conversion properties even at temperatures above 100°C. Here, the formation property refers to the film repairing ability for repairing a defect in the dielectric oxide film when the defect is generated. [0003] In addition, the above-mentioned non-aqueous electrolytic solution for driving is easy to deteriorate due to the esterification reaction at high temperature, so 1,6-decanedicarboxylic acid, 5,6-deca...
