Description
Technical field
The present invention is a kind of capacitor batteries electricity core and preparation method thereof, belongs to the renovation technique of capacitor batteries electricity core and preparation method thereof.
Background technology
Along with the growing tension of petrochemical industry resource and being on the rise of environmental pollution, new energy field is subjected to people and more and more payes attention to.The great demand in fields such as electric tool, motor vehicle, Aero-Space, defence and military, electronic information and instrument and meter makes that with ultracapacitor and lithium-ion-power cell be the focus that the power type green energy-storing device of new generation of representative becomes global high-tech industry field.
Lithium rechargeable battery is the novel energy-storing device that has grown up since nineteen nineties.Lithium ion battery has the energy density higher than Ni-MH battery, has heavy-current discharge performance preferably concurrently simultaneously.Though Sony takes the lead in proposing and being put to the LiCoO of industrialization in nineteen ninety
2/ C battery system is widely applied in the compact electric apparatus, but owing to reasons such as poor stability, cost height can not be as the power supply of hybrid vehicle.In recent years, people have developed novel anode material, as LiMn2O4, LiFePO4 etc., these materials have wide material sources, cheap characteristics, especially the long-life of LiFePO4 and high safety have caused people's very big concern, are expected to solve to a certain extent the fatal problem of lithium ion battery as the hybrid power power supply.Yet also there is a series of problem in lithium manganate battery at present because the dissolving of anodal manganese does not cause cycle performance good and high-temperature behavior is poor; The lithium ion battery of making by LiFePO 4 material, though by doping vario-property make its electronic conductivity be improved significantly, at present power density is still lower, cryogenic property is also not ideal, and its compacted density is low to make troubles to cell making process, also has obstacle aspect practical.
Ultracapacitor also is the novel green energy storage device that develops rapidly in recent years, and it has the fast charging and discharging characteristic, and power density is tens times even a hundred times of common batteries.Have extended cycle life in addition, the charge and discharge cycles number of times can reach 100,000 times, is the hundred times of common batteries even several thousand times.Based on this special performance of ultracapacitor, comprise that some countries of China have started the motor vehicle development project of use ultracapacitor as power supply, and successfully be applied on the city bus.But also there is fatal weakness in ultracapacitor as power supply on vehicle, and this is by the operation principle decision of himself.Present ultracapacitor is mainly based on two kinds of principles, a kind of is representative " electric double layer principle " with the absorbent charcoal material, the generation of its electric capacity is mainly based on the electric double layer capacitance that separation of charge produced on the electrode/electrolyte interface, and its electrolyte is mainly KOH or H in aqueous systems
2SO
4The aqueous solution, in non-aqueous system, be mainly the propene carbonate or the acetonitrile solution of quaternary ammonium salt, ionic conductivity is more than 13 mS/cm; Another kind is representative " a pseudo capacitance principle " with metal oxide and conducting polymer materials, the generation of its electric capacity is based on electroactive ion at material surface generation underpotential deposition, or at material surface and the inner absorption pseudo-capacitance that the redox generation takes place, its electrolyte is mainly KOH or H
2SO
4The aqueous solution, present technology is not also used in non-aqueous system.But no matter be the ultracapacitor of any principle, its operating voltage in aqueous systems is difficult to surpass 1.5 V, operating voltage is difficult to surpass 3.5 V in non-aqueous system, and because the redox reaction of similar battery does not take place in electrode material in electrolyte, according to the derivation of energy formula E=1/2CV of capacitance
2As can be known, its energy density significantly is lower than secondary cell (be about lithium ion battery 1/10).
High power density, the long circulation life of the high-energy-density of lithium ion battery and ultracapacitor combined becomes the emphasis of dynamic power system research.The combination of lithium ion battery and ultracapacitor has dual mode, a kind of is " outer combination " formula (both monomers are combined into an energy storage component or system by power management), this " outer combination " formula is actually the simple series and parallel of lithium ion battery and ultracapacitor, can not fundamentally solve lithium ion battery and ultracapacitor self-defect separately; Another kind is " interior combination " formula (being about to both organically is combined in the same monomer), positive active material adopts the compound or composite material of anode material for lithium-ion batteries and super capacitor material in the monomer of this " interior combination " formula, negative electrode active material adopts the compound or composite material of lithium ion battery negative material and super capacitor material, and the energy storage device that is somebody's turn to do " interior combination " formula is super capacitance cell.This super capacitance cell that constitutes by " interior combination ", can avoid lithium ion battery and ultracapacitor separately defective and keep the two advantage separately such as high-energy-density of high power and the overlength cycle life and the lithium ion battery of ultracapacitor, the energy storage device of super capacitance cell was paid close attention to especially in recent years.
At present, the general employing of super capacitance cell pole piece preparation is coated on lithium ion battery electrode material and super capacitor material on the collector by simple mixing or composite pulping, and then is assembled into superbattery electricity core.Yet, there are very big difference in lithium ion battery electrode material and electrode material for super capacitor, in pulping process, adhesive, solvent, conductive agent etc. are differed greatly in technology and technologic requirement, if simply these two kinds of material mixing or compounding ingredient slurrying then there is electrode material difficulties in dispersion in solvent, painting parameter is difficult to problems such as control, electrode material and collector bonding difference.The electric core of this method preparation, its both positive and negative polarity or material are difficult to give full play to advantages such as super capacitance cell high power, overlength cycle life, high-energy-density.
