Description
Technical field
The present invention relates to a kind of electrolytic capacitor paper, particularly a kind of super electrolytic capacitor paper.
Background technology
Electrolytic capacitor is one of base electronic element very important in the electronic engineering.It except filtering, coupling and bypass effect are arranged, also plays special role at special circuit such as correcting circuit, power circuit and ac motor starting circuit in electronic circuit.Be widely used in fields such as military project, civilian communications equipment, audiovisual system, control apparatus and electronic instrument.Electrolytic capacitor paper is the gasket material of absorption electrolyte in the electrolytic capacitor, and its performance directly influences the quality of electrolytic capacitor.
Along with the high speed development of electronics technology, electrolytic capacitor develops rapidly towards miniaturization, high-qualityization, high reliability and long-life direction.Tackle electrolytic capacitor paper mutually and propose higher requirement, the exploitation of the senior electrolytic capacitor of new product often relies on the exploitation of novel electrolytic capacitor paper.Super electrolytic capacitor (Supercapacitor) is the novel power-type electronic devices and components that occur along with the breakthrough of material science in recent years.It has filled up specific energy and specific power blank between ordinary capacitor and the battery, has high extremely thousands of farads capacitance, the electric current that sparks can reach thousands of amperes, in brief, it is with advancing to have the capacitance of battery and the fast charging and discharging performance of capacitor, also have the characteristics safe and reliable, that the scope of application is wide simultaneously, be to improve and the applicable breakthrough components and parts of solution electric energy dynamic property, and can as chemical cell or battery, do not pollute environment.Ultracapacitor has huge using value and market potential at aspects such as automobile (particularly electric automobile, fuel combination automobile and exceptional load vehicle), electric power, railway, communication, national defense industry (particularly MISSILE LAUNCHING and communication), consumption electronic products, by countries in the world institute extensive concern.Because super electrolytic capacitor has the characteristic of vast capacity, many developed countries all are used for military equipment with it, at first this capacitor is used for heavy truck, armored personnel carrier and tank as the U.S., has guaranteed quick, the clean boot of used vehicle under low temperature condition.And super electrolytic capacitor paper wherein is one of core raw material of this super electrolytic capacitor.
Because the positive electrode of ultracapacitor is fine ground absorbent charcoal material, its particle diameter minimum have only 2 μ m, that is to say that the paper maximum diameter of hole as isolated material should prevent that carbon granule from passing through below 2 μ m, cause electric leakage after arriving negative pole, great master's carbon granule by the back with regard to short circuit.So the requirement to paper is that the maximum diameter of hole is little, the porosity height.
(number of patent application is Chinese invention patent: 200310109194.0) announced a kind of low tightness high strength electrolytic capacitor paper, because what the fibrous raw material that uses was the thinnest is sisal hemp, its width is at 14-15 μ m, electrolytic capacitor paper by its making is used on the ultracapacitor, maximum characteristics are that leakage current is big, and the energy-storage property of capacitor is bad.
Summary of the invention
The objective of the invention is to solve the defective in the above-mentioned background technology, a kind of super electrolytic paper that ultracapacitor uses that satisfies is provided, its paper tightness is low, intensity good, and the aperture is little and even, is suitable for use on the ultracapacitor.Tightness is low to make its loss low, can not increase the internal resistance of ultracapacitor, and intensity makes the processing of its suitable ultracapacitor well, and the little leakage current of ultracapacitor that will make in aperture is little, makes it to be fit to energy storage.
In order to realize above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of super electrolytic capacitor paper, this super electrolytic capacitor paper are copied paper by pineapple fibre fiber and tencel fiber and are constituted, and the pineapple fibre fiber is 10～80% by weight percentage, and tencel fiber is 20～90%.The pineapple fibre fiber is higher than 80%, and the porosity of page is little, and the loss of paper is too big, can not satisfy the requirement of ultracapacitor, is lower than 10%, and the intensity of page is bad, is difficult to satisfy the requirement of strength of ultracapacitor assembling process.
As preferably, a kind of super electrolytic capacitor paper according to claim 1 is characterized in that: the pineapple fibre fiber is 30～70% by weight percentage, and tencel fiber is 30～70%.Preferred again, the pineapple fibre fiber is 40～60% by weight percentage, and tencel fiber is 40～60%.
Super electrolytic capacitor paper of the present invention is made of jointly pineapple fibre fiber and tencel fiber, and page can be an individual layer, also can be multilayer.Wherein the beating degree of pineapple jute pulp is 18～88 ° of SR, and the degree of beating of day silk can be between 15～86 ° of SR.Degree of beating height, the intensity of page is all right, and fiber divides silk fully simultaneously, and the aperture of page is little, and leakage current is just little, but loss meeting height.The degree of beating is low, and loss is just low, but the intensity of paper can reduce simultaneously, and leakage current can increase.Preferred again, the beating degree of pineapple jute pulp is 25～65 ° of SR, and the degree of beating of tencel fiber is 55～85 ° of SR.
Because the thickness of page is by the volume decision of ultracapacitor, its thickness range should be at 30-60 μ m, because to the intensity of paper and the balance of porosity, the tightness of its paper is at 0.20-0.50g/cm
3
The present invention is owing to adopted above-mentioned technical scheme, the pineapple jute pulp is the paper making raw material of occurring in nature diameter minimum in the above-mentioned component, its diameter thickness is at 4 μ m, the diameter of the overwhelming majority is about 2 μ m, and is longer as its length of a kind of jute pulp, generally about 3mm, such fiber paper strength is very high, and, satisfy the strict demand of ultracapacitor to leakage current because fiber finer becomes the paper aperture little.And a day silk is a kind of novel environment friendly viscose, and its production process is not discharged alkali lye, and environment is not polluted.A silk biggest advantage is can wire-dividing broom purification in papermaking day, and its fiber fines of telling is all rounded, with the flat filament of string great difference is arranged, the paper of making low tightness of such fibrous raw material is very suitable, and because the silk that divides is very thin, minimum at 1～2 μ m, its aperture of the page of making is little, satisfies the requirement of ultracapacitor to isolated material.
Its paper tightness of super electrolytic capacitor paper of the present invention is low, intensity good, the aperture is little and even, tightness is low to make its loss low, can not increase the internal resistance of ultracapacitor, intensity makes the processing of its suitable ultracapacitor well, the little leakage current of ultracapacitor that will make in aperture is little, makes it to be fit to energy storage, is suitable for use on the ultracapacitor.
