Abstract
The core of the super capacitor is composed of the sintered nickel oxide positive electrode piece, the negative electrode piece with the foaming nickel based on the specific material being coated and the folding continuous diaphragm. With the current terminals being welded, the core of the capacitor is put into the plastic case. After the electrolyte being fed into the plastic case and the case being sealed, the finished super capacitor is produced. The super capacitor possesses the high power density and energy density, the long service life. The super capacitor can be charged and discharged for many cycles suitable for the motive source of various electric motor cars.
Description
One, technical field:
The present invention relates to a kind of ultracapacitor, particularly disclose a kind of ultracapacitor, belong to a kind of novel electrochemical energy storage device in the electricity electric component as the power train in vehicle application power supply.
Two, background technology:
Along with electric motor car and hybrid electric vehicle technology as one of the most great high-tech brainstorm project beginning of this century, energy technology field extremely common people is paid close attention to.The weakest technically link of electric motor car and hybrid electrically truck system just is present in energy field.Lead acid accumulator, nickel-hydrogen accumulator are by the electrical source of power of numerous automotive development merchants as instruction carriage, but these two kinds of battery systems are the business-like main difficulties of restriction in performance and defective in price.The safety issue of lithium-ions battery self and a fuel cell hydrogen source difficult problem can not obtain basic solution at short notice.Can predict, above-mentioned two kinds of energy application on electric motor car and hybrid electric vehicle have certain degree of difficulty.Ultracapacitor is individual as a kind of model electrochemical energy storage device, remedied many deficiencies of energy-storage battery, its concentrated advantage shows as specific capacity, specific power is big, discharges and recharges rapidly, long-life and cleaning, pollution-free etc. are 21 century one of desirable environment-friendly type energy devices.
In patent documentation, existing super capacitor is done the example of power supply on vehicle, has announced as patent CN1160455 and has used the preparation method of absorbent charcoal material as the automobile-used capacitor of the symmetry structure of both positive and negative polarity.
Three, summary of the invention:
Problem to be solved by this invention is: a kind of power train in vehicle application power supply ultracapacitor with more high power density and energy density, with low cost, long service life is provided.
Technical scheme of the present invention is: it comprises positive pole, negative pole, barrier film, electrolyte and housing, it is characterized in that: the barrier film of separating positive and negative plate is continuous, by folding mode the multi-disc positive and negative plate is separated, and constitutes the capacitor core of parallel-connection structure; Sintered type nickel oxide sheet just very; Positive and negative electrode electric current leading-out terminal in the capacitor core is welded on the positive negative terminal; Design has safety valve in the middle of the housing; Barrier film is one of following material, nylon cloth, all-glass paper, PP, PE microporous barrier, polyvinyl alcohol film and asbestos paper; Electrolyte is alkali lye, potassium hydroxide solution the best of 6mol/l concentration.Barrier film in the ultracapacitor of the present invention's design is a continuous distribution, by folding mode the multi-disc positive and negative electrode is isolated, for cutting out barrier film between each capacitor core unit and the capacitor core, the barrier film of continous way has improved production efficiency to this method separately.Simultaneously, the present invention adopts under the low-temperature condition.
Four, description of drawings:
Accompanying drawing schematic diagram of the present invention.
Among the figure: 1. positive plate, 2. thin nickel sheet, 3. negative pole, 4. binding post, 5. housing, 6. cap, 7. safety valve
Five, embodiment:
Sintered type nickel oxide sheet is cut into rectangular of certain size, and reserves lug as the electric current leading-out terminal; Cut out barrier film, and, form the septate positive plate 1 of parcel in the accompanying drawing with barrier film parcel sintering oxidation nickel sheet.
Cut the thin nickel sheet 2 of certain size, the collector and the supporter of the negative pole 3 that constitutes as activated carbon fiber cloth give and stay lug as the electric current leading-out terminal.
The activated carbon fiber cloth negative pole 3 that multi-disc is wrapped up septate positive plate 1 and the thin nickel sheet 2 of multi-disc and serialization and parcel positive pole is assembled into capacitor core.
With ultrasonic wave or welding machine and binding post 4 welding, the capacitor core after the welding places plastic casing 5, and perfusion electrolyte with the positive and negative electrode electric current leading-out terminal in the capacitor core.
Stretch out positive and negative electrode binding post 4 from plastics cap 6 two ends, with ultrasonic wave or hot plate machine with cap 6 and housing 5 sealings, ultracapacitor.Design has safety valve 7 on cap 6.
The capacitance of this invention ultracapacitor is greater than 3000F, and power density is greater than 2.5Kw/kg, and energy density is near 5Wh/kg.
Claims (6)
