Description
Technical field
The present invention relates to the inorganic system's ultracapacitor of a kind of pair of high pressure, more particularly, to a kind of to the isostructural improvement of high-voltage super capacitor.
Background technology
Ultracapacitor, it is called double layer capacitor ultracapacitor, after on applied voltage to two pole plates, ion in electrolyte can be adsorbed on pole plate and complete polarization, the charge and discharge process of ultracapacitor is physical process all the time, without chemical reaction, therefore ultracapacitor can be hundreds thousand of secondary with repeated charge.Ultracapacitor is a kind of novel energy storage apparatus between traditional capacitor and battery, and it has the advantages that, and power density is big, capacity big, long service life, non-maintaining, economic and environment-friendly.
Traditional inorganic system's ultracapacitor, monomer voltage is usually no more than 1V, once reaching window voltage, pole piece will occur electrolysis water reaction, produce oxygen and hydrogen, and such case causes application of the ultracapacitor in higher voltage field to be restricted.Simultaneously a large amount of gases produce and electric capacity can be caused to rupture, and cannot be continuing with, different from the rich solution electric capacity of organic series, the electric capacity electrolyte comparision contents of inorganic series are low, if the perforate design being similar to using lead-acid accumulator, water inside electric capacity monomer can evaporate quickly causes integral capacitor internal resistance huge, it is impossible to use.Although inorganic series has the problems referred to above, but compare the high voltage of organic series, for high energy storage, inorganic series is more environmentally-friendly, it is safer, will not explode, and inorganic series also has its unique use, such as the application in terms of automobile starting, diesel locomotive startup, hybrid vehicle startup.Therefore, the frame mode of inorganic series super capacitor at present is improved, the monomer voltage and raising force resistance for improving ultracapacitor is extremely urgent.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of inorganic series super capacitor of the high pressure of more safety and pressure tolerance, it mainly solves existing mineral condenser, and in process of production the bad caused internal resistance of monolithic uniformity is too high, the force resistance for reaching the gas produced after window voltage is poor, and the technical problem of the environmental resistance ability in use.
The technical scheme is that for this：The inorganic system's ultracapacitor of double high pressure, including encapsulating housing, it is characterised in that：Form according to the order compacting that is stacked together of epoxy resin bar, positive power taking pole plate, capacitor monomer, negative power taking pole plate, epoxy resin bar in encapsulating housing；The capacitor monomer of at least 30 and the above is provided between wherein positive and negative pole plate, capacitor monomer assembled in series is formed, is spaced by barrier film between each two capacitor monomer.
Further it is improved by：Described positive and negative power taking pole plate is conductive stainless steel or alloy pole plate, and two pieces of power taking pole plates stretch out respectively a lug as external power supply.
Further it is improved by：Described capacitor monomer is plaster contg. active ingredients, and plaster contg. active ingredients are made up of flow collection sheet with the activated carbon powder for being coated on flow collection sheet both sides, and the reserved 3-5 mm frames of surrounding of flow collection sheet and insulation frame coordinate, and flow collection sheet material is stainless steel band or nickel strap.
Further it is improved by：Described plaster contg. active ingredients are super-activated carbon, alkaline electrolyte is mixed and is coated on flow collection sheet, and slabbing is reduced after drying.
Further it is improved by：The area of barrier film is consistent with active material size；The area of barrier film is less than the area of flow collection sheet, makes barrier film that plaster contg. active ingredients can be just completely covered.
Further it is improved by：Described pressing pressure size is in 5-13 T.
Beneficial effect：
Epoxy resin bar rather than epoxy resin board are adopted in the present invention, encapsulating epoxy resin can be flowed between power taking pole plate and housing when so pouring, and play more preferable insulation effect and sealing effectiveness.Due to the good heat insulation anti-shock performance of the epoxy resin filled with firm shell and the inside, this kind of electric capacity is used under conditions of the scope and strenuous vibration of high low temperature, simultaneously because pressurization assembling and excellent sealing, short time overvoltage is charged and is also not result in electric capacity crack damage, and overvoltage is adjusted to into rated voltage electric capacity can be continuing with.
Positive and negative power taking pole plate is indeformable for two pieces of pole plates of stainless steel or alloy pole plate are resistant to the pressure of some strength.
The carbon dust of plaster contg. active ingredients surrounding 3-5 mm before the use is scraped, and then insulate frame on pad, will not out when such carbon dust is extruded, and barrier film also can be intercepted completely；The length of barrier film is consistent with active material size with width；And in addition barrier film is the super inorganic series capacitors dedicated diaphragm paper with suitable aperture；The area of diaphragm paper is smaller than the area of flow collection sheet, that is, active material can be just completely covered in diaphragm paper；Flow collection sheet and barrier film so when pressurization assembling between adjacent two panels causes short circuit all without contact.
After plaster contg. active ingredients are stirred by super-activated carbon, alkaline electrolyte, it is coated on flow collection sheet, slabbing is reduced after drying and is formed.All can be improving the bonding of carbon dust and collector using adhesive or dispersant in general battery processing, adhesive and dispersant can cause the increase of internal resistance, due to finally using huge pressure compaction electric capacity monomer in the present invention, carbon dust will not arbitrarily flow and come off, therefore adhesive and dispersant need not be added in active material, is so increased the capacity of electric capacity and reduced internal resistance；The scheme that adjustment pressure obtains consistent internal resistance is employed simultaneously, improves the stability of product.
The flow collection sheet and barrier film when being arranged on pressurization assembling between adjacent two panels of diaphragm size causes short circuit all without contact.
The uniformity of electric capacity is ensure that using the pressure of 5-13 T.
