Abstract
The utility model discloses a kind of solid capacitor negative pole carbon paper tinsel, comprise corrosive aluminum foil layer, this corrosive aluminum foil layer has coarse upper, lower surface, coarse upper of described corrosive aluminum foil layer, lower surface is coated with respectively with aluminium and graphite affinity all stronger upper by the mode of magnetron sputtering, lower intermediate metal, on, the outer surface of lower intermediate metal is coated with respectively by the mode of magnetron sputtering, lower graphite linings, on described, lower intermediate metal and upper, lower graphite linings have respectively coarse with described corrosive aluminum foil layer on, lower surface matches coarse on, lower transition zone surface and coarse on, lower graphite linings surface.Graphite linings of the present utility model is not easy to come off, and the utility model product has compared with long useful life, the feature such as capacitance is large, leakage rate is low, impedance is little.
Description
Technical field
the utility model relates to a kind of solid capacitor negative pole carbon paper tinsel.
Background technology
Electric capacity mainly as charge storage, ac filter, prevention direct voltage, the use of tuning and vibration is provided, the electric capacity of different structure has different capacitance characteristics, function and application scope is also different.Wherein taking aluminium foil as basement membrane, surface recombination have graphite form solid capacitor negative pole carbon paper tinsel, because its capacitance is high and manufacturing cost is relatively low, be widely used and promote.
The structure of the solid capacitor negative pole carbon paper tinsel using is at present mainly by aluminium foil be compounded in its lip-deep graphite and form; the phenomenon that the solid capacitor negative pole carbon paper tinsel of said structure often there will be graphite to come off from aluminium foil surface in actual use, has affected useful life of electric capacity.In order to prevent that graphite from coming off, extending useful life of solid capacitor negative pole carbon paper tinsel from aluminium foil surface, in prior art, occur that employing binder is coating aluminium foil surface after graphite-made pulp, although the electric capacity of this structure can prevent that graphite from coming off from aluminium foil surface to a certain extent, but owing to having added binder, electric conductivity and the capacity ratio of electric capacity are affected, the electric capacity of said structure end fundamentally solve the problem that graphite comes off from aluminium foil surface in addition, also can occur occasionally the phenomenon that graphite comes off in electric capacity use procedure.
Utility model content
The technical problems to be solved in the utility model is to provide the solid capacitor negative pole carbon paper tinsel that a kind of capacitance is high and relatively grow useful life.
For solving the problems of the technologies described above, a kind of solid capacitor negative pole of the utility model carbon paper tinsel, comprise corrosive aluminum foil layer, this corrosive aluminum foil layer has coarse upper, lower surface, coarse upper of described corrosive aluminum foil layer, lower surface is coated with respectively with aluminium and graphite affinity all stronger upper by the mode of magnetron sputtering, lower intermediate metal, on, the outer surface of lower intermediate metal is coated with respectively by the mode of magnetron sputtering, lower graphite linings, on described, lower intermediate metal and upper, lower graphite linings have respectively coarse with described corrosive aluminum foil layer on, lower surface matches coarse on, lower transition zone surface and coarse on, lower graphite linings surface.
As further improvement of the utility model, the metal in described intermediate metal is preferably chromium, titanium, zirconium or stainless steel.
Adopt the solid capacitor negative pole carbon paper tinsel of said structure, owing to adopting coarse upper of described corrosive aluminum foil layer, lower surface is coated with respectively with aluminium and graphite affinity all stronger upper by the mode of magnetron sputtering, lower intermediate metal, on, the outer surface of lower intermediate metal is coated with respectively by the mode of magnetron sputtering, the technical characterictic of lower graphite linings, therefore aluminium foil layer and intermediate metal have stronger adhesion, intermediate metal and graphite linings also have stronger adhesion, graphite linings is not easy to come off, so adopt the utlity model has longer useful life of said structure, in addition, because the compound of graphite linings and aluminium foil layer is by intermediate metal, can not affect capacitance of the present utility model, leakage rate is relatively low, because described upper and lower intermediate metal and upper and lower graphite linings have respectively coarse upper and lower transition zone surface and the coarse upper and lower graphite linings surface of matching with the coarse upper and lower surface of described corrosive aluminum foil layer, this is equivalent to increase specific area of the present utility model, makes the utlity model has larger capacitance.Metal in described intermediate metal is preferably chromium, titanium, zirconium or stainless steel, not only makes intermediate metal of the present utility model have better affinity, also makes this practicality have better electric conductivity and capacitance, leakage rate is low simultaneously.
