At present it is known that or medium-high voltage aluminum electrolytic capacitor Working electrolyte, have passed through following development
Process: one, using ethylene glycol as main solvent, the inorganic compounds such as boric acid or ammonium pentaborate are main solute.The work electricity prepared in this way
Solution liquid has that conductivity is low, and boric acid and its salt easily occur esterification with ethylene glycol at high temperature and generates a large amount of
Condensation water, cause the moisture content inside electrolyte to increase, the vapour pressure of electrolyte increases, and capacitor internal pressure increases and causes
The failure of capacitor valve opening；Two, using ethylene glycol as main solvent, using the direct-connected hydrocarbon saturation two such as azelaic acid, decanedioic acid or 12 diacid
Carboxylic acid and its salt are electrolyte solution, although this kind of electrolyte avoids a part of esterification, but due to this
Solubility of a kind of linear paraffin in ethylene glycol is smaller, causes the impedance of product larger, is easy fever under big ripple and makes
Solvent volatilization causes capacitor withered and fails, while amide easily occurs at high temperature for linear paraffin to generate vicious circle
Change side reaction and generate water, also easily causes capacitor initial failure；Three, using some branched acid or its salt, 1 such as reported,
6-DDA and its salt and 2- butyl octanoic acid and its salt, this kind of branched carboxylic acid and its salt compare straight chain to the solubility of solvent
Alkane increases, thus produces effect to a certain extent, but simultaneously, and this kind of acid or its salt rely primarily on import, because forming
This height and restraining factors are more.
