Description
Technical field
The present invention relates to the Preparation of Activated Carbon field, relate in particular to the preparation method of a kind of electrode for capacitors with metallic absorbent charcoal.
Background technology
Ultracapacitor (electrochemical capacitor) is a kind of between store battery and traditional capacitor, based on the energy-storage travelling wave tube of the electrochemical process at electrode/electrolyte interface.Its capacity derives from electric double layer capacitance and pseudo capacitance, it has the big and high characteristics of storage battery energy density of ordinary capacitor power density concurrently, have excellence continuous fast charging and discharging performance, have extended cycle life, use temperature wide ranges, non-maintaining, advantages of environment protection.Ultracapacitor all has wide practical use in a lot of fields, as aerospace, military affairs, industry, civil area or be used to adjust electric load separately, store electric power, or mix use with the device of generation electric energy such as fuel cell, solar cell, wind-power electricity generation, oil engine.
Studies show that the electrode materials of ultracapacitor is one of key factor of its performance of restriction, the electrode materials as ultracapacitor mainly is porous carbon material and metal oxide and hydrate thereof at present.
What porous carbon material mainly produced is electric double layer capacitance, because of its stable performance, existing donor state have acceptor state, environmental friendliness again, more application is in capacitor electrode material, particularly the gac that cost is cheap relatively has flourishing hole, great surface-area, can adsorb more electrolyte ion, storage more energy with its preparation electrode, become the main raw material of preparation of industrialization electrode of super capacitor.Yet electrode active carbon is comparatively harsh to the research of pore structure: micropore (＜2nm) be main gac, because its hole is less, be unfavorable for the quick travel of electrolyte ion, make that the surface-area utilization ratio is lower, the low temperature capacity is affected; Mesopore activated carbon (though＞2nm) its hole helps the quick travel of electrolytic solution, and the rapid large-current discharge performance is superior, and specific surface area is less relatively, and energy stored is also less, influences its energy density and power density.So have more mesopore concurrently and be the preferred material of making electrode than the gac of bigger serface.
The main effect of metal oxide and hydrate thereof is to produce pseudo capacitance, and some metallic compounds are (as RuO
2XH
2O etc.) and electrolytic solution redox reaction can take place on its surface, electrode is by the reaction of faraday's electrode fast stored energy.At present, the ratio electric capacity of studying compounds such as maximum rutheniums, iridium is higher, but is noble metal, is difficult to bear on price; Compounds such as some cheap metals such as copper, cobalt, nickel, manganese also have the pseudo-capacitance phenomenon to take place, but it is lower than electric capacity, influences practical application.
For improving electrode performance, it is the more method of studying at present that the finished product gac is carried out blended metal oxide, and it can take into account the pseudo-capacitance effect of the electric double layer capacitance and the metal of gac.As: people such as Ling Licheng are in patent " a kind of doping cheap metal improves mesopore activated carbon and compares capacitive method; publication number CN1410350A ", a kind of method for preparation of active carbon of blended metal oxide is provided, it specifically is source from the preparation gac, consider directly to utilize resol, cheap organic metal salt, ferrocene, hexamethylenetetramine, methanol mixed, stirring and refluxing is cured, processing step such as charing and activation makes electrode active carbon again.Though this method has played certain effect, it is higher to have cost of material equally, and the source is restricted, the problem of the loaded down with trivial details harshness of preparation technology.
