Row regulation and control.
Content of the invention
For deficiencies such as prior art preparation porous charcoal nanometer sheet needed raw material high cost, technical sophistications, the present invention proposes
A kind of low cost, process is simple, the controlled ultracapacitor preparation method of washing oil base porous charcoal nanometer sheet.
The method comprises the following steps that：
(1) pretreatment of reactant：Hydroxide flake potassium is put into and in mortar, is ground to powder, by powdered potassium hydroxide
Mix homogeneously with nano-calcium carbonate, then be gradually added into stirring in washing oil, mix homogeneously obtains mixture；Wherein, washing oil with
The mass ratio of nano-calcium carbonate is fixed as 1/1.5；The mass ratio of washing oil and potassium hydroxide is between 1/2～1/3；
(2) preparation of washing oil base porous charcoal nanometer sheet:The mixture of step (1) gained is put in corundum porcelain boat, and will
Corundum porcelain boat is placed in tube furnace, is passed through the air in tube furnace described in high-purity argon gas emptying, will with the heating rate of 3 DEG C/min
Tube furnace is warming up to 550 DEG C, constant temperature 30min, continues, with the heating rate of 3 DEG C/min, tube furnace is warming up to 800～900 DEG C
Final temperature, is naturally cooling to room temperature after constant temperature 60min at this temperature.After the product obtaining is taken out, grinds, remove through pickling
Go template, distilled water wash to neutral, after being dried, obtain washing oil base porous charcoal nanometer sheet.
With the washing oil base porous charcoal nanometer sheet of gained of the present invention as active substance, with aqueous polytetrafluoroethyldispersion emulsion for bonding
Agent, with nickel foam as colelctor electrode, preparation work electrode, and it is assembled into symmetric form ultracapacitor.Can in 6M KOH electrolyte
Electrochemical property test is carried out to gained porous charcoal nanometer sheet material.
Compared with prior art, the present invention has following technique effect：
1st, with washing oil as carbon source, washing oil is rich in multi-ring armaticity micromolecular compound, can be used as module rapid build charcoal
Nanometer sheet；With nano-calcium carbonate as guiding die plate, template is cheap and easy to get.
2nd, Calcium Carbonate is adopted to be template, it is decomposed into calcium oxide and carbon dioxide when 550 DEG C, in situ the titanium dioxide of release
Carbon can be worked in coordination with chemical activating agent potassium hydroxide as physically activated dose and be played pore-creating effect, and calcium oxide can be received to porous charcoal
Rice piece plays catalyzed graphitization effect.
3rd, as electrode material for super capacitor, porous charcoal nanometer sheet of the present invention shows good chemical property,
In 6M KOH electrolyte, under 0.05A/g electric current density, the specific volume of porous charcoal nanometer sheet reaches 222F/g；In 20A/g electric current density
