Abstract
The invention discloses a high-energy-storage capacitive unit. The high-energy-storage capacitive unit comprises an electrolyte, a positive electrode and a negative electrode. The electrolyte can comprises an electroconductive polymer, the positive electrode and the negative electrode are arranged in the electrolyte at an interval, and the positive electrode comprises a base material and a transition metal oxide layer formed on the base material. By means of the high-energy-storage capacitive unit, the capacitance efficiency can be substantially improved.
Description
Technical field
The present invention relates to electrochemical energy storage technology, in particular to a kind of high storage capacitor unit.
Background technology
Owing to energy shortage problem is day by day serious, in order in response to each field such as green demand can transported with electric power, the application of electrochemical energy storage technology is increasingly extensive.Ultracapacitor (supercapacitor) is a kind of performance occurred in recent years novel energy-storing assembly between secondary cell and traditional capacitor, its capacitance is up to the even thousands of farad of farad level, and possess the advantage that traditional capacitor power density is big, energy density is high, and therefore ultracapacitor also has extremely wide application prospect in various fields such as mobile communication, information technology, electric automobile, aviation and science and techniques of defence.
Based on square principle being directly proportional of the energy density of ultracapacitor and power density and operation voltage, the electrolyte with high voltage degree of stability is used to become extremely important.But, the voltage range allowed by water system electrolyte commonly used is 1V, thus limits the operable voltage of capacitor batteries；On the other hand, the non-water system electrolyte such as organic solvent commonly used, it easily presents unsure state because of features such as inflammable and high volatility in heat and electrochemical environment, therefore is unfavorable for that capacitor batteries operates under the condition of high temperature.
Except electrolytical selection, the selection of electrode material is also the key factor of the general performance affecting ultracapacitor.The electrode material commonly used mainly has carbon-based material and metal-oxide two kinds, with carbon-based material, although Porous active carbon material has bigger specific surface area, but because its crystallinity is poor, electric conductivity is bad, thus being unfavorable in electrode transmitting procedure the transfer of electronics.Furthermore, the equivalent series resistance (ESR) adopting the capacitor of active carbon material electrode is big, and the specific surface area utilization rate of capacitor is less than 30%, and actually electrolyte ion is difficult to enter, therefore capacitive property cannot effectively promote.
Carbon nanotube (CNT) is the seamless nm level tubular crystal curling by graphite linings, and its degree of crystallinity is high, specific surface area is big and specific surface utilization rate can reach 100%, thus can directly as the electrode material of ultracapacitor.But, prepare carbon nanotube raw material used by membrane electrode and be generally Powdered and very easily reunite, and carbon nanotube skewness and be likely to occur the state of lack of alignment in the membrane electrode made in this way, therefore need carbon nanotube is carried out chemical modification.Simply carbon nanotube after being chemically modified is still it may happen that the extensive phenomenon reunited, and makes the degraded toughness of obtained membrane electrode, is susceptible to brittle fracture, affects the performance of ultracapacitor on using.
Therefore, develop the ultracapacitor that a kind of capacitance is high and power density is big and really have its necessity and urgency.
Summary of the invention
The present invention is from the angle of capacitive property, and main purpose ties up in providing a kind of high storage capacitor unit with splendid electro-chemical activity.
For reaching above-mentioned purpose, one embodiment of the invention provides a kind of high storage capacitor unit, and it includes an electrolyte, an anelectrode and a negative electrode.Described anelectrode is arranged in described electrolyte, and described anelectrode comprises the transition metal oxide layer that a base material and is formed on described base material, and described negative electrode is arranged in described electrolyte and relative to each other with described anelectrode.
Another embodiment of the present invention provides a kind of high storage capacitor unit, and it includes an electrolyte, an anelectrode and a negative electrode.Described anelectrode is arranged in described electrolyte, and the material of described anelectrode is the mixture of porous carbon materials and the transition metal oxide material of nm size, and described negative electrode is arranged in described electrolyte and relative to each other with described anelectrode.
In sum, the present invention, through the utilization of transition metal oxide composite material anode, can have preferably electro-chemical activity and supercapacitor properties, to greatly improve the capacitance efficiency commonly using ultracapacitor, and then can have broad application prospects.
The other objects and advantages of the present invention can be further understood from the technology contents that disclosed herein.In order to the above and other purpose of the present invention, feature and advantage can be become apparent, special embodiment below also coordinates institute's accompanying drawings to be described in detail below.
