Description
Technical field
The utility model relates to a kind of two high pressure inorganic systems ultracapacitor, especially relates to a kind of to the isostructural improvement of high-voltage super capacitor.
Background technology
Ultracapacitor, be again double electric 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, there is no chemical reaction, therefore ultracapacitor can repeated charge hundreds thousand of time.Ultracapacitor is a kind of Novel energy storage apparatus between traditional capacitor and storage battery, the advantages such as it has, and power density is large, capacity is large, long service life, non-maintaining, economic environmental protection.
Traditional inorganic system ultracapacitor, monomer voltage is generally no more than 1V, once reach window voltage, brine electrolysis reaction will occur pole piece, produces oxygen and hydrogen, and this situation makes ultracapacitor be restricted in the application in more high voltage field.A large amount of gas generation simultaneously can cause electric capacity to break, and cannot continue to use, be different from the rich solution electric capacity of organic series, the electric capacity electrolyte comparision contents of inorganic series is low, if the perforate design adopting lead acid accumulator similar, water inside electric capacity monomer can evaporate very soon and cause integral capacitor internal resistance huge, can not use.Although inorganic series has the problems referred to above, but compare the high voltage of organic series, high energy storage, the environmental protection more of inorganic series, safer, can not blast, and inorganic series also has the use of its uniqueness, the application such as in automobile starting, diesel locomotive startup, hybrid vehicle startup.Therefore, improve the frame mode of current inorganic series super capacitor, the monomer voltage and the raising force resistance that improve ultracapacitor are extremely urgent.
Summary of the invention
The utility model technical issues that need to address are to provide the inorganic series super capacitor of high pressure of a kind of safety more and pressure tolerance, it mainly solves existing mineral condenser, and the bad internal resistance caused of monolithic consistency is too high in process of production, the force resistance of the gas produced after reaching window voltage is poor, and the technical problem of environmental resistance ability in using.
The technical solution of the utility model is for this reason: two high pressure inorganic system ultracapacitor, comprise encapsulating housing, it is characterized in that: form according to the compacting that is stacked together of the order of epoxy resin bar, battery lead plate of officiallying enroll, capacitor monomer, negative power taking pole plate, epoxy resin bar in encapsulating housing; Wherein be provided with at least 30 and above capacitor monomer between positive and negative pole plate, capacitor is monomer series-connected to be assembled, by barrier film interval between every two capacitor monomers.
Further improvement is: described positive and negative power taking pole plate is stainless steel or the alloy pole plate of conduction, and two pieces of power taking pole plates stretch out a lug respectively as external power supply.
Further improvement is: described capacitor monomer is plaster contg. active ingredients, plaster contg. active ingredients is made up of flow collection sheet and the activated carbon powder being coated on flow collection sheet both sides, the surrounding of flow collection sheet reserves 3-5mm frame and insulation frame coordinates, and flow collection sheet material is stainless steel band or nickel strap.
Further improvement is: described plaster contg. active ingredients is super-activated carbon, alkaline electrolyte is mixed and be coated on flow collection sheet, is cut into sheet after drying.
Further improvement is: 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 just in time can cover plaster contg. active ingredients completely.
Further improvement is: described pressing pressure size is at 5-13T.
Beneficial effect:
Adopt epoxy resin bar instead of epoxy resin board in the utility model, when building like this, encapsulating epoxy resin can flow between power taking pole plate and housing, plays better insulation effect and sealing effectiveness.Due to the heat insulation anti-shock performance that the epoxy resin with firm shell and the inside filling is good, this kind of electric capacity can be used under the condition of the scope of high low temperature and strenuous vibration, simultaneously due to pressurization assembling and excellent sealing, short time overvoltage charging also can not cause electric capacity crack damage, overvoltage is adjusted to rated voltage electric capacity and can continue to use.
Positive and negative power taking pole plate is that stainless steel or alloy pole plate two pieces of pole plates can tolerate the pressure of some strength and indeformable.
The carbon dust of plaster contg. active ingredients surrounding 3-5mm is before the use scraped, and then pad insulate frame, can not out when such carbon dust is extruded, and barrier film also can intercept completely; The length of barrier film is consistent with width and active material size; And barrier film is the super inorganic series capacitors dedicated diaphragm paper with suitable aperture in addition; The area of diaphragm paper is smaller than the area of flow collection sheet, namely just in time can cover active material completely at diaphragm paper; Flow collection sheet like this when pressurization assembling between adjacent two panels and barrier film all can not contact and cause short circuit.
Plaster contg. active ingredients is coated on flow collection sheet after being stirred by super-activated carbon, alkaline electrolyte, is cut into sheet and forms after drying.Adhesive or dispersant all can be used to improve the bonding of carbon dust and collector in the processing of general battery, adhesive and dispersant can cause the increase of internal resistance, owing to finally using huge pressure compaction electric capacity monomer in the utility model, carbon dust can not arbitrarily flow and come off, therefore do not need in active material to add adhesive and dispersant, increase the capacity of electric capacity like this and reduce internal resistance; Have employed the scheme that adjustment pressure obtains consistent internal resistance simultaneously, improve the stability of product.
Diaphragm size be arranged on pressurization assembling time adjacent two panels between flow collection sheet and barrier film all can not contact and cause short circuit.
The pressure of 5-13T is used to ensure that the consistency of electric capacity.
