Abstract
The utility model discloses a top cover of an inorganic super capacitor, which relates to a shell structure of a capacitor. The improvement of the top cover is that a liquid filling hole is arranged in the middle part, an annular stand is arranged in the liquid filling hole, a porous filter disc is arranged in the through hole of the inside of the annular stand, a rubber sleeve is arranged at the top part of the annular stand, and a cover plate with a vent hole is arranged at the upper end opening of the liquid filling hole. The top cover is used for encapsulating the inorganic super capacitor, electrolyte solution is filled from the liquid filling hole, gas which reaches a certain pressure can be smoothly discharged from the capacitor, so leakage of the electrolyte solution is effectively prevented, the safety and reliability are good, the structure is compact, and the volume is small, so the capacitor with large capacity is convenient to install and assemble, and the utility model also simplifies the manufacture technology of the capacitor and reduces the cost of the capacitor.
Description
Technical field
The utility model relates to a kind of inorganic ultracapacitor loam cake, belongs to ultracapacitor shell structure technical field.
Background technology
Ultracapacitor (supercapacitor) claims capacitor with super capacity, gold electric capacity, storage capacitor again, is the energy storage device between capacitor and battery.It had both had the characteristics that capacitor can fast charging and discharging, had the energy storage mechanism of electrochemical cell again.It provides than higher capacitance of Ni-MH battery and lower environmental pollution, does not have memory effect substantially with the price a little more than Ni-MH battery, is a kind of battery of environmental protection.Advantages such as inorganic ultracapacitor has the specific power height simultaneously, the speed that discharges and recharges is fast, in light weight, life-span length, non-environmental-pollution, become a kind of novel energy storage device, has important and wide application prospect in fields such as mobile communication, information technology, consumer electronics, electric automobile, Aero-Space and science and techniques of defence, worldwide cause very big concern, become the new forms of energy product that countries in the world are competitively developed and developed.
In recent years because primary energy anxieties such as oil, and progressively being rooted in the hearts of the people of environmental protection concept, the inorganic ultracapacitor of large-capacity power type also more and more is subject to people's attention, the inorganic ultracapacitor of power is except that can being used for electric bicycle, motorcycle, hybrid vehicle, simultaneously can also be widely used in beeliner, electric locomotive, large-scale military, civilian naval vessel and small-sized electric pleasure-boat, movable electric tool such as electric saw, hay mover, building, machine room and the back-up source facility of communicating by letter etc.
Inorganic ultracapacitor is after long-term the use, its electrolyte inside can be decomposed and emitted gas, make internal pressure increase, the at present big inorganic ultracapacitor of capacity adopts the method that installs safety valve on battery top in addition additional to solve more, and safety valve is opened and discharged gas in the shell when inside reaches certain pressure.Take out of together but have alkaline electrolyte in the gas of discharging tends to battery under situations such as overcharging, tilt, keep flat, cause corrosion and damage housing outer connection component, electronic devices and components.Simultaneously the volume of safety valve is generally bigger, and gives prominence in outside, influence profile and is inconvenient to put in order the connection of Battery pack and installs and fixes.
The utility model content
The purpose of this utility model be bigger than normal at the existing existing safety valve easy-to-leak liquid of the inorganic ultracapacitor of big capacity, volume, be not easy to the fixing shortcoming of whole group connection, a kind of simple and compact for structure, not easy-to-leak liquid, novel inorganic ultracapacitor loam cake safe and reliable, easy to install are provided.
The technical solution of the utility model is: inorganic ultracapacitor loam cake, respectively there is a terminal delivery outlet at two ends, its improvements are that the middle part of loam cake is provided with liquid injection hole, hollow important actor is arranged in the liquid injection hole, in the through hole of hollow important actor inside the porous filtering sheet is housed, the rubber cap bag that is positioned at porous filtering sheet top is equipped with at hollow important actor top, and the upper port of liquid injection hole is provided with cover plate, and steam vent is arranged on the cover plate.
Further scheme is: described porous filtering sheet is polypropylene or polytetrafluoroethylene member, and porosity is＞80%, aperture 2～60 μ m; Described cover plate upper air-vent aperture is 1.2～2mm; Gap between described rubber cap bag and the cover plate is 6～10mm; The upper port and the lower port of described terminal delivery outlet are equipped with annular groove.
Be provided with liquid injection hole in the middle of this inorganic ultracapacitor loam cake, after cell package, can inject electrolyte to inside battery by this liquid injection hole.Change into and daily use in after a small amount of gas of producing of inside battery reaches certain pressure, gas extruding rubber cap bag make its with hollow important actor between produce slit discharge internal gas.Internal gas can freely pass through the porous filtering sheet, but electrolyte is when running into the porous filtering sheet of material such as polytetrafluoroethylene, because the effect of surface tension of liquid and being intercepted can not revealed through liquid injection hole.Distance between cover plate and the rubber cap bag can the control capacitor pressure inside.
Cover plate is provided with one or more steam vents, will discharge the capacitor outside through the gas that the rubber cap bag is discharged by steam vent, when internal pressure hour, the rubber cap bag is pressed on the hollow important actor.Because the aperture that steam vent is suitable and the effect of porosity and rubber cap bag make the water and the gas of outside can not enter capacitor inside.
This inorganic ultracapacitor loam cake has the function of safety valve simultaneously, can effectively prevent the phenomenon of leakage, and is safe and reliable.The utility model has saved safety valve, and the annular groove of the upper and lower port of terminal delivery outlet is respectively in order to gluing and dress sealing ring, and compact conformation, sealing are reliably, making is easy, cost is low, adopt the inorganic super capacitor of this loam cake that combined and instant is installed.
Description of drawings
Accompanying drawing is inorganic ultracapacitor loam cake cross-sectional view.
Embodiment
Example 1: referring to accompanying drawing, inorganic ultracapacitor loam cake 9 is by ABS engineering plastics injection molded, there is terminal delivery outlet 6 at two ends, its upper and lower port has annular groove 1 and 10 respectively, be provided with liquid injection hole 3 in the middle of the loam cake, be provided with hollow important actor 8 in the liquid injection hole, place porosity in the through hole of hollow important actor and be 85%, the aperture is the porous filtering sheet 5 of 10 μ m, rubber cap bag 2 is equipped with at the top, the liquid injection hole upper port is provided with cover plate 4, four steam vents 7 are arranged on the cover plate, and aperture 1.2mm has the 6mm gap between cover plate and the rubber cap bag.
Example 2: be with example 1 difference: porous filtering sheet 5 porositys are 82%, aperture 50 μ m, and the aperture of the steam vent 7 on the cover plate 4 is 2mm, between cover plate 4 and the rubber cap bag 9mm gap is arranged.
