Description

NiCo for ultracapacitor2O4@MnMoO4Nucleocapsid structure porous nanometer material and Its preparation method
Technical field
The present invention relates to the field of electrode material for super capacitor, particularly to a kind of binary gold for ultracapacitor Belong to oxide combination electrode material and preparation method thereof.
Background technology
Along with the fast development of global economy, the fossil energy such as oil, natural gas constantly consumes, and environmental pollution day is increasingly Play, the sustainable development of economy and society is severely impacted.To this end, people actively find and develop various clean energy resource, as Solar energy, wind energy, tide energy, nuclear energy, bioenergy etc..At energy field, efficiently, low cost, the long-life, the eco-friendly energy Storage system is extremely important.Wherein, ultracapacitor is novel between traditional capacitor and secondary cell of a kind of performance Energy storage device, has an advantage that power density is high, is equivalent to 5-10 times of battery;Charge/discharge rates is fast, can be at several seconds to several Complete in minute;Temperature range width, can work under-40 ~ 70 DEG C of environment;Have extended cycle life;Non-maintaining, environmental protection.Therefore, Ultracapacitor is increasingly subject to extensive concern, leads with military affairs etc. in consumer electronics, electric power, machinery, new-energy automobile, space flight and aviation All there is huge application prospect in territory.
Ultracapacitor is mainly made up of positive and negative two electrodes, collector, barrier film and four parts of electrolyte, wherein affects The most crucial factor of ultracapacitor chemical property is electrode material.How to obtain the electrode material that performance is more excellent, be scientific research Personnel do one's utmost the difficult problem captured.Design electrode material for super capacitor, should include following character: (1) specific surface area wants big, to obtain Obtain more active site;(2) to have suitable pore-size distribution, gap network, and the length in hole, to promote that ion expands at a high speed Dissipate;(3) in electrode, internal conductance wants height, to provide effective charge transfer;(4) chemical property and mechanical stability to be got well, To obtain good cycle performance.
According to the mode of energy storage, ultracapacitor can be divided into two kinds.One, double layer capacitor, electrode material master If material with carbon element, in the electrolyte, electric charge is separated from each other, and produces an electric double layer, the type on carbon electrode/electrolyte interface Capacitor storage electric charge relies on the electric double layer of electrode and electrolyte interface to realize, the only accumulation of static electricity of surface charge, institute Relatively low with specific capacity of double-layer capacitor.Its two, Faradic pseudo-capacitor, also referred to as pseudocapacitors, generally with oxo transition metal Compound and conducting polymer, as electrode material, utilize the electrochemical redox reaction of fast electric active substance or at electrode table The quick adsorption desorption in face stores electric charge, completes charge and discharge process, and the ratio electric capacity of pseudocapacitors is higher.
