The advantages such as close friend.Ultracapacitor all has wide practical use in many fields, as mobile communication,
Information technology, Aero-Space, science and techniques of defence, civil area or be individually used for adjust electric load, storage
Electric power, or produce the device of electric energy with fuel cell, solaode, wind-power electricity generation, internal combustion engine etc.
It is used in mixed way.The chemical property improving ultracapacitor that the most increasing research is paid close attention to, especially
It improves it than electric capacity, charge-discharge performance etc..Current research surface, the electricity of ultracapacitor
Pole material is one of key factor restricting its performance, and the big specific surface area that absorbent charcoal material has,
High mesoporous, low resistivity, stable chemical performance, pore structure are controlled, cheap, source
The advantage such as extensively so that it is as the ideal electrode material of ultracapacitor.Therefore, ratio how is prepared
The absorbent charcoal material that surface area is big, mesoporous is high, total pore volume the is big electrochemistry to improving ultracapacitor
Performance has vital effect.
It is built upon roentgen Helmholtz using activated carbon as the ultracapacitor of electrode material
A kind of brand-new capacitor in interfacial electric double layer theoretical basis proposed, the performance of its electrode material is certainly
Determine the service behaviour of double layer capacitor, such as electrode conductivity, electrode specific surface area etc..Super
The carbon electrode material that level capacitor is conventional has the active carbon powder of loose structure, a CNT etc., and work
Industry mainly uses active carbon powder on producing.It is generally acknowledged that the specific surface area of electrode material is in certain journey
On degree, the capacitance size with double layer capacitor is linear correlation, and therefore many manufacturers are in order to carry
The active carbon powder that high product capacitive property, selection particle size and aperture are the least, such powder
Owing to specific surface area is big, it is super that the specific capacity of double-layer capacitor prepared is big, energy density is higher
Level electric capacity, but the energy-storage property of this double layer capacitor still cannot be with other storages such as battery, lithium battery
Energy equipment is comparable.Simultaneously because carbon powder particle is the least, cause making in the double layer capacitor obtained
Resistance is big, and the discharge and recharge time is slow, and power density is low, loses advantage and the spy of super capacitor self completely
Point.The most how in power density and energy density, to find a suitable equilibrium point, be the most double
The research and development key point of electric layer capacitor electrode material, can give full play to self spy of double layer capacitor
Long.
