Referring to fig. 1, the present invention relates to a reactive compensation dry capacitor, which is characterized in that the reactive compensation dry capacitor comprises:
the reactive compensation dry type capacitor comprises a shell 1 and a reactive compensation dry type capacitor body 2, wherein the reactive compensation dry type capacitor body 2 is arranged in the shell 1, the reactive compensation dry type capacitor body 2 comprises a polar plate, and the polar plate comprises a substrate and an electrode layer arranged on the surface of the substrate.
The manufacturing method of the polar plate comprises the following steps:
(1) sequentially carrying out ultrasonic vibration cleaning on the carbon fiber cloth by using an acetone solution, an alcohol solution and a deionized water solution, and then putting the carbon fiber cloth into a baking oven for drying; putting the carbon fiber cloth into a zinc acetate absolute ethyl alcohol solution for ultrasonic vibration cleaning, and then putting the carbon fiber cloth into the baking oven for drying; and putting the carbon fiber cloth into a nitrogen environment for annealing treatment.
In this way, the carbon fiber cloth forms a zinc oxide layer on the surface.
(2) Mixing a zinc acetate solution and a hexamethyltetramine solution to obtain a first mixed solution, putting the carbon fiber cloth into the first mixed solution, maintaining the fixed temperature for a period of time (preferably repeating the above process at least once), and then putting the carbon fiber cloth into the baking oven to be dried after being cleaned by deionized water.
Thus, the zinc oxide layer starts to grow zinc oxide nanowires.
(3) Mixing a nickel nitrate solution and a potassium permanganate solution to obtain a second mixed solution, putting the carbon fiber cloth into the second mixed solution for electrochemical deposition, cleaning the carbon fiber cloth with deionized water, and putting the carbon fiber cloth into the baking oven for drying.
Therefore, the nickel-manganese hydroxide nano-layer can grow on the surface of the zinc oxide nano-wire. In addition, during the electrochemical deposition process, the counter electrode and the reference electrode are preferably selected from platinum and silver chloride, respectively.
(4) And putting the carbon fiber cloth into a high-temperature furnace for thermal annealing treatment, cleaning the carbon fiber cloth with deionized water, putting the carbon fiber cloth into the baking oven for drying, so that the nickel-manganese hydroxide nano-layer becomes a nickel-manganese oxide nano-layer, and finally arranging the carbon fiber cloth on the surface of the substrate to complete the polar plate.
Through the above description, the electrode layer of the present invention has nickel-manganese hydroxide, zinc oxide nanowires, and carbon fibers, and the zinc oxide nanowires greatly increase the overall surface area and thus increase the overall specific capacitance. In the aspect of service life, the maintenance rate of the invention is about 86% after more than 3000 circles of tests by using a pulse electrodeposition method, and the invention has the advantage of long service life.
Example 2:
referring to fig. 4, the electrolyte of the reactive compensation dry capacitor body 2 is preferably a colloidal polyelectrolyte film. The following describes a method of manufacturing the colloidal polyelectrolyte thin film:
(1) adding polyethylene glycol (PEG), deionized water and nitrogen into a double-neck reactor, heating and stirring for a period of time, preferably at about 40 ℃, adding acrylonitrile (PAN) into the double-neck reactor, and heating and stirring for a period of time, preferably at about 40 ℃; dissolving ceric nitrate amine into a nitric acid solution to obtain a third mixed solution; and slowly adding the third mixed solution into the double-neck reactor until complete reaction to obtain a heterogeneous solution, performing air-suction filtration on the heterogeneous solution, then repeatedly cleaning the heterogeneous solution by deionized water and acetone for multiple times, and then performing drying treatment, preferably drying the heterogeneous solution in a vacuum oven at about 80 ℃ to obtain PAN-b-PEG-b-PAN triblock copolymer polymer, wherein the chain segment ratio between AN and EG in the PAN-b-PEG-b-PAN triblock copolymer polymer can be adjusted by changing the weight of acrylonitrile. The molecular formula of the PAN-b-PEG-b-PAN triblock copolymer is as follows:
(2) putting PAN-b-PEG-b-PAN triblock copolymer polymer, lithium perchlorate and dimethylformamide into a container, heating the container by a high-temperature oven at about 80 ℃ to obtain a homogeneous polymer electrolyte solution, putting a trace (such as 0.1g) of the homogeneous polymer electrolyte solution into an aluminum disc, and heating the aluminum disc to evaporate the dimethylformamide to obtain the colloidal polymer electrolyte film.
The colloidal polyelectrolyte film has a special linear structure through the triblock copolymer, and can effectively reduce the ion mobility resistance (equivalent series resistance) and the mass transfer diffusion resistance (Warburgregation) in impedance. In summary, the synergistic effect of acrylonitrile and ethylene glycol can greatly improve the surface of the reactive compensation dry capacitor in terms of energy storage performance, specific energy, specific power, etc., for example, at a specific power of 10 kWkg-1Under the condition of (1), the specific energy can reach up to 21Wh kg-1At a low discharge rate of 0.12Ag-1Under the condition of (2), the maximum specific energy can also be up to 30kWkg-1。

Therefore, through the top wall 11 and the strip-shaped plate 4 which are spaced apart from each other, the conductive terminals 3 can be more stably disposed on the top surface of the housing 1, and are not easily damaged by external force.
Example 4:
referring to fig. 5, in order to ensure the safety of the present invention during the use of electricity, the present invention further makes each conductive terminal 3 electrically connected to a discharge resistor 5, and each discharge resistor 5 is disposed outside the top wall 11 of the housing 1.
