Abstract
An energy storage device with an interleaved distributed inner parallel structure is provided. The positive electrode of the energy storage device is composed of activated carbon electrode areas and lithium-containing compound electrode areas which are staggered distributed on the same aluminum foil current collector. The negative electrode of the energy storage device is composed of activated carbon areas and lithium-containing compound areas which are staggered distributed on the same aluminum foil current collector. In the energy storage device, the activated carbon areas of the positive electrode are corresponded to the activated carbon areas of the negative electrode, thus a super capacitor unit is formed. The lithium-containing compound electrode areas of the positive electrode are corresponded to the lithium-containing compound areas of the negative electrode to form a lithium ion battery unit. By using the interleaved distributed inner parallel structure provided by the present invention, the capacity ratio of the super capacitor unit and the lithium ion battery unit can be adjusted by changing the areas of the respective electrodes (i.e., the mass of electrode active materials). By changing the capacity ratio of the super capacitor unit and the lithium ion battery unit, a super capacitor/lithium ion battery hybrid energy storage device having different output characteristics can be designed and manufactured. In addition, the use of the interleaved distributed inner parallel structure does not encounter the problem that high surface density activated carbon electrodes are difficult to produce in batch in the production of inner series connection super capacitor/lithium ion battery hybrid energy storage device.
Description
Technical field
The invention belongs to ultracapacitor and secondary cell field, be specifically related to a kind of energy storage device with parallel-connection structure in the formula of being interspersed that is consisted of by ultracapacitor cell and lithium ionic cell unit.
Background technology
In recent years, the exhaustion of primary energy and environmental pollution become the urgent problems of concern of society day by day, and therefore the utilization of various power-saving technologies and secondary energy sources also has been subject to people's extensive concern.Ultracapacitor is a kind of novel energy-storing device between conventional electrostatic capacitor and secondary cell, having the secondary cell power density that is beyond one's reach, but energy density is on the low side.Lithium ion battery is as a kind of novel secondary cell, and the advantage of its high-energy-density also makes it be widely used in fields such as mobile phone, notebook computers, but since the restriction of its material itself so that the lithium ion battery power density is on the low side.In order to overcome the problems referred to above, researchers have proposed hybrid super capacitor structure that ultracapacitor and lithium ion cell electrode are carried out combination.Wherein representational work is: the people such as Amatucci (Amatucci G.G., et al., An asymmetric hybrid nonaqueous energy storage cell, J.Electrochem.Soc., 148, A930-A939,2001) adopting nano lithium titanate is negative pole, active carbon is anodal, assembles out the mixed type lithium ion capacitor take the LiPF6/AN of 1.5M as electrolyte system, and its energy density reaches 20Wh kg
-1, the charge/discharge capacity conservation rate reaches 90% under the 10C multiplying power.
Can find out that from the structure of above-mentioned hybrid super capacitor this class capacitor anode or negative pole all adopt independently capacitor material or lithium ion battery material, can regard the energy storing structure that battery pole and capacitance pole combine and form by interior series system as.But, the people such as Cericola (Cericola D., et al., Hybridization of electrochemical capacitors and rechargeable batteries:Anexperimental analysis of the different possible approaches utilizing activatedcarbon, Li

4, J.Power.Sour., 196,10395-10313,2011) studies show that the mixed capacitor structure of interior tandem type is subjected to the restriction of battery pole material in power density, and is subjected to the restriction of capacitance pole material in energy density.Final result adopts the hybrid capacitors energy density of this interior cascaded structure assembling slightly higher than double electric layer capacitor, but power density is only suitable with battery, and effect does not improve significantly.
In addition, there is such problem in interior tandem type hybrid super capacitor in both positive and negative polarity coupling: because the capacity of lithium ion battery material will be far above the capacitor absorbent charcoal material, just require when carrying out the both positive and negative polarity coupling according to the conservation of electricity principle active carbon lateral electrode quality be approximately lithium ion battery material 3-5 doubly.The electrode production process of lithium ion battery and ultracapacitor mainly is take coating technique as main at present, and the coated face density of lithium ion battery material is generally at 20mg cm
-2About, require activated carbon electrodes side coated face density needs to reach 60-100mg cm according to coupling
-2, these surface density data are very inaccessible in present activated carbon electrodes coating process.The high areal density activated carbon electrodes need to adopt coating technique to be prepared, but present coating technique (U.S. Maxwell technology) is very difficult, although the ultracapacitor performance of working it out is more superior, production cost and technical bottleneck are so that the application of coating technique has been subject to larger restriction.
The problems referred to above based on interior tandem type mixed capacitor, the people such as Cericola (Cericola D., et al., Hybridization of electrochemical capacitors and rechargeable batteries:Anexperimental analysis of the different possible approaches utilizing activatedcarbon, Li

4, J.Power.Sour., 196,10395-10313,2011) and interior parallel connection type energy storing structure has been proposed: in double electric layer capacitor both positive and negative polarity absorbent charcoal material, add respectively a certain proportion of LiMn2O4 or lithium titanate.Because interior parallel connection type energy storing structure both positive and negative polarity had all both comprised capacitance material and also comprised battery material, this just makes interior parallel connection type energy storing structure provide the high-octane while also can provide high power.Ratio by control capacitance material and battery material just can effectively be regulated and control power output and energy.The vertical plateau in Chaoyang also has similar energy storing structure in its patent CN101699590A, add a certain proportion of phosphoric acid alum oxygen lithium (perhaps LiFePO 4, LiMn2O4) in anode activated charcoal, adds a certain proportion of lithium titanate in the cathode activated charcoal simultaneously.Capability retention can reach the relative 1C of 91%(under the 10C multiplying power), capability retention is 97% under 2000 circulation 1C multiplying powers.
Although above-mentioned interior parallel-connection structure energy-storage units has overcome the shortcoming of interior series hybrid capacitor, but because absorbent charcoal material is the coating of being undertaken by the mode of mixing with battery material in this interior parallel-connection structure, zwitterion takes off the interference that embedding all can be subject to another kind of material at the adsorption desorption of activated carbon surface and lithium ion in battery material, this is so that the efficient of the utilance of material and energy storage device has been subject to certain impact.
