Background technology
With the development of society and the progress of science and technology, people are to the charge/discharge rates of energy storage component, life-span, power density
With the requirement more and more higher of energy density.Therefore, when charge/discharge rates are fast, efficiency for charge-discharge is high, long lifespan, environment-friendly super
Level capacitor when occurring people it is scintillating so that ultracapacitor become current people in green energy-storing area research and
The focus of development, it is also widely used in the field such as number, automobile, medical treatment, health, power electronics, communication, the energy, military.
With the expansion in supercapacitor applications field, its usage amount is also increasing year by year, so ultracapacitor is annual
Learies will also increase with surprising rapidity, if to the super capacitor scrapped without scrapping processing, not only waste big
The resource of amount, certain pollution can be also caused to environment.So the recycling to scrapping ultracapacitor, has very great
Social benefit and economic benefit.
The content of the invention
It is an object of the invention to provide a kind of recovery method of waste and old ultracapacitor, the recovery of ultracapacitor is realized again
Utilize, and can economize on resources, environmental protection, there is good Social benefit and economic benefit.
To achieve the above object, the technical solution adopted by the present invention is：A kind of recovery method of waste and old ultracapacitor, bag
Include following steps：
1）Waste and old ultracapacitor accumulates discharge process together；
2）Waste and old ultracapacitor is broken into 1 ~ 5mm of diameter sheet in closed explosion-proof disintegrating machine, what is crushed
Spray liquid is sprayed simultaneously, the quaternary ammonium salt electrolyte in waste and old ultracapacitor is dissolved in spray liquid；
3）Ultracapacitor shell is separated by being sirred and separated；
4）By step 3）Suspension centrifuge dripping after sirring and separating obtains the mixing of sheet stock and electrolyte and spray liquid
Liquid；
5）Sheet stock is put into constant temperature calcining stove, roasting carbonizes barrier film and binding agent；
6）Activated carbon and aluminium foil are separately recovered using the method for centrifugation.
In the method, step 2）Described is broken into diameter in closed explosion-proof disintegrating machine by waste and old ultracapacitor
3mm sheet
In the method, the ultracapacitor is cylinder double electric layers supercapacitor.
In the method, the step 2）Spray liquid be organic solvent or the mixed liquor of organic solvent and water.
In the method, the organic solvent is ethanol, methanol, acetone, chloroform or isopropanol.
In the method, the step 2）Spray liquid recycle after filtering.
In the method, the step 2）Spray waste and old ultracapacitor is crushed using highly pressurised liquid atomizing spray technology
Process is sprayed.
In the method, the step 5）The temperature of roasting is 300 DEG C ~ 800 DEG C, and pressure is less than -80Kpa.
Advantages of the present invention effect is：Due to present invention uses this recovery method, realizing waste and old super capacitor
The recovery and comprehensive utilization of device, solve the problems, such as waste and old ultracapacitor safe retrieving, and with method is easy and effective, warp
Help high efficiency, it is pollution-free the advantages that, the invention reduces the pollution that waste and old ultracapacitor is brought to environment, is ultracapacitor
Cost degradation provide a new way, there is very high Social benefit and economic benefit.
