Detailed description of the invention
Fig. 1 is the Making programme schematic diagram of the capacitor of one embodiment of the invention.Refer to Fig. 1, first,
Carry out step S100, it is provided that porous matrix 100.Porous matrix 100 has multiple hole, therefore
There is high specific surface area.The material of porous matrix 100 e.g. tripolycyanamide, polystyrene, poly-
Urethane, polyethylene, ethene-vinyl acetate co-polymer, hot plastic rubber, polrvinyl chloride or other high scores
Sub-polymer.
In one embodiment, optionally porous matrix 100 is carried out.Can use acetone or
Other cleanout fluid clean porous matrix 100, with remove on the surface of porous matrix 100 with hole
Interior impurity.But the invention is not restricted to this, it is also possible to porous matrix 100 is carried out the most common clear
Clean process remove on the surface of porous matrix 100 with the impurity in hole.
Then, carry out step S110, nano-carbon material 102 is added in electrolyte 104, mix nanometer
Material with carbon element 102 and electrolyte 104 so that nano-carbon material 102 is dispersed in electrolyte 104, with
Obtain electrolyte constituent 106.The electrolyte 104 e.g. potassium hydroxide that in this step, used,
Sodium hydroxide or sulphuric acid.In one embodiment, nano-carbon material 102 e.g. carbon aerogels.Carbon airsetting
Glue can have the particle size particle between 3nm to 20nm.Carbon aerogels has the structure of porous, and
Its porous (porosity) can be more than 50%, and therefore carbon aerogels has high specific surface area.In this reality
Executing in example, the specific surface area of carbon aerogels is such as between 400m2/ g to 1000m2Between/g.Due to carbon

Toast.Certainly, the invention is not restricted to this, in another embodiment, can be by porous matrix 100
Stand volatilization and be dried program.
Then, step S130 is carried out, on relative two surface 100a, 100b of porous matrix 100
Form electrode 108a, 108b (refer to Fig. 2) respectively.In the present embodiment, at porous matrix 100
Relative two surface 100a, 100b upper formed electrode 108a, 108b method e.g. by electrode 108a,
108b is attached on relative two surface 100a, 100b of porous matrix 100.Electrode 108a, 108b
Material e.g. silver, palladium or aluminum.So far, i.e. complete there is porous matrix 100 and electrolyte
The making of the capacitor 10 of constituent 106.
In capacitor 10, owing to porous matrix 100 has highly porous, there is high specific surface area,
The electrolyte constituent 106 of the most adsorbable volume.Further, since receiving in electrolyte constituent 106
Rice material with carbon element 102 also has highly porous and high specific surface area, the electrolyte of the most adsorbable volume
104.It is to say, in capacitor 10, nano-carbon material 102 all can be inhaled with porous matrix 100
The electrolyte 104 of attached volume, therefore can be effectively improved the charge storage capacity of capacitor 10.Additionally,
Owing to electrolyte constituent 106 can be adsorbed at porous matrix 100 by porous matrix 100 effectively
Surface on hole, the most also can be effectively prevented from the leakage problem of capacitor.
Additionally, capacitor of the present invention can have nano-carbon material and electricity by being first immersed in by porous matrix
Solve in the electrolyte constituent of liquid, on the apparent surface of porous matrix, form electrode afterwards made
Become, therefore processing procedure is simple and without using excessively complicated equipment, therefore cost of manufacture is low.
