Relative to electrode material, the concern that electrolyte is subject to is substantially less.
The electrolyte of ultracapacitor mainly has water system, organic system, ionic liquid and solid electrolyte at present, but all
In the presence of it is certain the shortcomings that, water system and organic system electrolyte have certain pollution, ionic liquid and solid electrolyte to environment
It is unstable, it is difficult to promote, therefore a kind of, it is necessary to new ultracapacitor electrolysis matter.
The content of the invention
The defects of in order to make up prior art, it is an object of the invention to provide a kind of ultracapacitor to be electrolysed matter.
A kind of ultracapacitor is electrolysed matter, is made up of the raw material of following parts by weight：1,4- butyrolactone 51 ~ 53, propylene carbonate
Ester 37 ~ 39,2- methyl-2-propanols 32 ~ 34, GMA 28 ~ 30,2-Hydroxy ethyl acrylate 24 ~ 26,
Sec-butyl acetate 13 ~ 15, acrylic acid-2-ethyl caproite 11 ~ 13, double trifluoromethanesulfonimide lithiums 1.6 ~ 1.8, lithium hexafluoro phosphate
1.1 ~ 1.3, benzyltriethylammonium chloride 0.3 ~ 0.5.
A kind of preparation method of ultracapacitor electrolysis matter, specifically includes following steps：
（1）1,4- butyrolactone, propene carbonate, GMA, 2-Hydroxy ethyl acrylate, acetic acid is secondary
Butyl ester and acrylic acid-2-ethyl caproite are well mixed, and double trifluoromethanesulfonimide lithiums and lithium hexafluoro phosphate are added, in 12 ~ 14
DEG C stirring to being completely dissolved, obtain mixture A；
（2）Benzyltriethylammonium chloride is added in 2- methyl-2-propanols, stirs to being completely dissolved, obtains mixture B；
（3）Mixture B is added in mixture A, is stirred under vacuum 30 ~ 40 minutes, 0.22 μm of miillpore filter is crossed, obtains super capacitor
Device electrolyte；
（4）Packaging, examine, obtain finished product.
It is an advantage of the invention that：A kind of ultracapacitor electrolysis matter provided by the invention, safety and environmental protection will not be because during use
Overcharging for capacitor causes noxious material to volatilize, environmental protection and health；Electrolyte viscosity is suitable, is easy to use, property
Stable, specific capacitance increase 10.8%, charge storage ability improves 13.5%, and sales volume improves 11.4%, and income improves 13.7%.
