Background technology
Ultracapacitor is again double layer capacitor, is a kind of electrochemical element, but does not change in the process of its energy storage
Learn reaction, and Electro Sorb and the desorption process of anions and canons simply occurs on the positive and negative pole plate of two porous, this
Plant thermal energy storage process completely reversibility, also just because of this ultracapacitor can be hundreds thousand of secondary with repeated charge.Ultracapacitor
Can be considered to suspend the porous electrode plate of two reactionless activity in the electrolyte, powers up on pole plate, and positive plate is inhaled
Drawing the anion in electrolyte, negative plate attracts cation, actually forms two capacitive accumulation layers, is just separated
Ion is near negative plate, and anion is near positive plate.
Ultracapacitor principle with porous carbon as active material is as follows: when applied voltage is added to two poles of ultracapacitor
Time on plate, as ordinary capacitor, the positive electrode storage positive charge of pole plate, negative plate storage negative electrical charge, at super electricity
Under the electric field action that on the two-plate of container, electric charge produces, form contrary electric charge at electrolyte with on interelectrode interface,
With on the internal electric field of BES, this positive charge and the negative electrical charge contact surface between two not homophase, with positive negative electricity
Between lotus, extremely short gap arrangement is on contrary position, and this charge distribution layers is called electric double layer.Due to electric capacity and pole plate table
Area is directly proportional, and and spacing between positive and negative charge be inversely proportional to, and the ratio that the polar plate area of ultracapacitor is porous carbon
Surface area, generally 1000～3000m2/ g, is more than 3～4 orders of magnitude, super capacitor than the surface area of traditional capacitor
Being spaced about 0.5nm between positive and negative charge in device, therefore the capacity of ultracapacitor is very big, can reach 1～5000F,
The capacitor of part particular design is even up to surprising 100,000 farad.
The critical material of decision ultracapacitor performance quality is its electrode material, and the electrode material of ultracapacitor is mostly adopted
With porous carbon materials, typically requiring that specific surface area is the highest more good, for same type of material, specific surface area is the biggest, material
The electric conductivity of material is the lowest, and pore volume is the biggest simultaneously.But the exigent power density of ultracapacitor and certain volume energy storage
Density, therefore electric conductivity and pore volume to material have certain requirement, and electric conductivity is the highest more good, and pore volume is about
1.0～1.3cm3/g.In prior art, porous carbon materials good conductivity, cost is high；Low cost, electric conductivity is poor.
The Chinese invention patent (publication date is on August 11st, 2010) of Publication No. CN101800131A discloses one
Active carbon-based material and preparation method thereof, uses under inert gas shielding, by doped or undoped polyaniline polymer
At 500-1200 DEG C of carbonization 1-24h, then carrying out high-temperature activation or solution activation process, described high-temperature activation is by carbon
Material after change and activator are incubated 0-20h at 100-1000 DEG C, and the activation of described solution is at sulphur by the material after carbonization
The solution of acid, nitric acid, hydrochloric acid, potassium permanganate, hydrogen peroxide etc. soaks 0.5-96h.But, the method prepares
The specific surface area of material with carbon element is the least, limits its further raising than electric capacity.

Weigh 100g manioc waste to put in the bucket equipped with 3L water, add pre-preserved material (NaOH:Na2SO3=4:1), in advance
Preserved material concentration is 3%, presoaks 30 minutes；Feed heat temperature raising subsequently, maintains 80 when pressure rises to 0.8MPa
Minute, open explosion；With water clean, extruding dry, under nitrogen protection, with speed, be warming up to 1000 DEG C, constant temperature
2 hours, obtain material with carbon element；Obtained material with carbon element is mixed according to mass ratio 80:10:10 with graphite, beta-schardinger dextrin,
With alcohol, this mixture is modulated into half siccative, grinds uniformly and be pressed into sheet, be washed into disk, in press-in two panels nickel foam,
100 DEG C are vacuum dried 24 hours, prepared experimental cell pole piece.With platinized platinum for electrode, electrolyte is 6mol/L hydrogen
Potassium oxide solution, uses the ratio electric capacity of cyclic voltammetry test material.
