Embodiment 1

[0037] please see figure 1 and Figure 6 , the present invention relates to a structural improvement of a metallized safety film explosion-proof capacitor, which is characterized in that it includes:

[0038] Housing 1, metallized safety film explosion-proof capacitor body 2, the metallized safety film explosion-proof capacitor body 2 is arranged in the housing 1, and the metallized safety film explosion-proof capacitor body 2 includes a first plate 21 and the second pole plate 22, the first pole plate 21 is preferably used as an anode, and the second pole plate 22 is preferably used as a cathode, and the first pole plate 21 includes a first substrate 211 and is located on the The first electrode layer 212 on the surface of the first substrate 211, the first electrode layer 212 is made of graphene mixed with activated carbon and doped with nickel oxide; the second plate 22 includes a second substrate 221 and is located on The second electrode layer 222 on the surface of the ...

Embodiment 2

[0052] please see Figure 4 , the electrolyte of the metallized safety film explosion-proof capacitor body 2 is preferably a colloidal polymer electrolyte film. The following introduces the manufacturing method of the colloidal polymer electrolyte film:

[0053](1) Take polyethylene glycol (PEG), deionized water and nitrogen into the double-neck reactor and heat and stir for a period of time. The temperature is preferably around 40°C, and then add acrylonitrile (PAN) to the double-neck reaction The reactor is then heated and stirred for a period of time, and the temperature is also preferably around 40°C; the cerium nitrate ammonium is dissolved in the nitric acid solution to obtain the third mixed solution; the third mixed solution is slowly added to the double-necked reactor, and wait until After the complete reaction, a heterogeneous solution is obtained. After the heterogeneous solution is suction-filtered, it is washed repeatedly with deionized water and acetone, and the...

Embodiment 3

[0058] please see figure 2 , the implementation method is: the surface of the housing 1 is provided with several conductive terminals 3 arranged in sequence at intervals, and each conductive terminal 3 is electrically connected to the metallized safety film explosion-proof capacitor body 2, and each conductive terminal 3 The top wall 11 of the housing 1 and the strip plate body 4 respectively pass through the bottom end of the housing 1 in sequence, and there is a distance between the strip plate body 4 and the top wall 11 of the housing 1 .

[0059] In this way, through the spaced apart top wall 11 and strip-shaped plate body 4 , the conductive terminals 3 can be more stably arranged on the top surface of the housing 1 , and are not easily damaged by external force.

Abstract

The invention discloses an improved structure of a metalized safety film explosion-proof capacitor. Graphene is mixed with activated carbon, and nickel oxide is doped to serve as a first electrode layer of a first polar plate; therefore, not only can the characteristic of good conductivity of the graphene be retained, but also the problem of low energy density of the graphene can be improved through nickel oxide, and the overall metalized safety film explosion-proof capacitor can be greatly improved in the aspects of conductivity and energy density. Furthermore, graphene is mixed with activated carbon and tungsten oxide is doped to serve as a second electrode layer of the second polar plate; therefore, through the mutual cooperation of the first electrode and the second electrode, the structure has better conductivity and larger surface area, and the internal resistance of the whole capacitor can be greatly reduced, so that the whole structure can have more complete capacitance characteristics, and has good performance in the aspects of specific capacitance value, power density, energy density and the like.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an improved metallized safety film explosion-proof capacitor structure. Background technique [0002] With the continuous development of electronic products, consumers not only have requirements for electronic products in terms of performance, innovation, and appearance, but also gradually start to care about whether electronic products can be used continuously for a long time. However, due to the lack of energy storage performance of traditional batteries, since capacitors gradually began to develop, their energy storage performance and output power have excellent performance, so everyone began to compete for research in order to greatly improve capacitors. output power and energy storage capacity. Contents of the invention [0003] In view of the above problems, the present invention provides an improved metallized safety film explosion-proof capacitor structure, and its ...
