Description
Technical field
The present invention relates to a kind of manufacture method of ultracapacitor manufacture method, particularly a kind of flexible packed super-capacitor.
Background technology
Ultracapacitor also belongs to double electric layer capacitor, it is a kind of of capacity maximum in the present double electric layer capacitor, the double electric layer capacitor of its basic principle and other kind is the same, all is the capacity that utilizes the double electrical layers acquisition super large of active carbon porous electrode and electrolyte composition.
In the double electric layer capacitor, adopt absorbent charcoal material to be made into porous electrode, while filling electrolyte solution between relative carbon porous electrode, when applying voltage at two ends, assemble positron-electron on the relative porous electrode respectively, and the negative ions in the electrolyte solution will gather respectively on the interface relative with positive/negative plate owing to electric field action, thereby forms two current collection layers, is equivalent to two capacitors in series and the double electric layers supercapacitor that constitutes.
Usually, ultracapacitor produces gas changing into Shi Douhui for the first time, as fails timely discharge and will influence the chemical property of ultracapacitor, when the air pressure of inside acquires a certain degree and fail in time to discharge decompression, the phenomenon of might blasting.Especially in flexible packed super-capacitor, in case produce gas and will be difficult to discharge, the possibility that above-mentioned phenomenon takes place increases greatly after packaged fully.
At present in the manufacturing process of flexible packed super-capacitor to gaseous emission problem neither one adequate solution way also.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, the manufacture method of a kind of safe and reliable, capacity foot, flexible packed super-capacitor that chemical property is good is provided.
Technical scheme of the present invention is: the manufacture method of flexible packed super-capacitor, comprise that electric core is made, aluminum plastic film packing and capacitor change into master operation, and its improvements are: it is as follows that described aluminum plastic film packing and capacitor change into method of operation:
(1) the electric core that has pole that conventional method is made is put into U-shaped aluminum plastic film bag, and inserts the liquid injection pipe of being with copper rod in aluminum plastic film bag one side, then the opening of aluminum plastic film bag and the junction of liquid injection pipe and aluminum plastic film bag is sealed;
(2) extract copper rod in the liquid injection pipe, be evacuated to 0.05～0.09MPa, inject water-based system or organic system electrolyte to electric in-core portion again, the reservoir quantity unanimity of each ultracapacitor monomer changes into after shelving 8～12h at normal temperatures then routinely;
When (3) changing into aluminum plastic film bag inner chamber is vacuumized, pressing in keeping is 0.01～0.05MPa, change into end after, mend electrolyte of the same race once more, the loss amount of electrolyte during the amount of mending equals to change into, promptly the benefit of electrolyte is gone into amount (weight) M=(M
0+ M
1)-M
2, M in the formula
0Be the weight of ultracapacitor before the fluid injection, M
1Be the electrolyte weight of injecting first, M
2For changing into the weight that finishes the back ultracapacitor, unit is kg.
Further scheme is: described liquid injection pipe is made by polypropylene, polyethylene or polyvinyl chloride; The heating-up temperature of described heat-sealing is 200～300 ℃; Described water-based system electrolyte is potassium hydroxide or sulfuric acid electrolyte; Described organic system electrolyte is that tetraethylammonium tetrafluoroborate salt or triethyl group methyl tetrafluoroborate are dissolved in the electrolyte that acetonitrile or propene carbonate constitute; Described injection electrolyte utilizes fluid injection machine or syringe or height above sea level pump to carry out.
The good effect of technical solution of the present invention is: a side of aluminum plastic film bag is inserted liquid injection pipe and is used to inject electrolyte and vacuumizes, and inserts copper rod in the liquid injection pipe, is convenient to the heat-sealing of liquid injection pipe and aluminum plastic film bag, and can adhesion in the liquid injection pipe after the assurance heat-sealing.Vacuumize earlier before injecting electrolyte, can guarantee fluid injection smoothly and reservoir quantity consistent, change into again after shelving 8～12h at normal temperatures after the fluid injection, can make electrolyte fully immerse electric core, the raising formation effect.Change into while vacuumizing when changing into, can in time discharge the inner gas that produces of capacitor, avoid ultracapacitor to have swell even explosion caused, improve the product safety reliability because of gas is arranged.Take the method for secondary fluid injection after changing into, replenish an amount of electrolyte, and the loss amount of electrolyte when amount infused is vacuumized in equaling to change into, prevent to cause the problem of condenser capacity deficiency on the one hand because of the electrolyte content deficiency, guarantee the electrolyte content unanimity in each capacitor monomer on the other hand, the cycle life of the module that the consistency during with raising capacitor combination of monomers and each monomer are formed obtains the excellent charging and discharging performance.
