Description

Alkali formula cobalt nitrate/ordered mesoporous carbon combination electrode material and preparation method thereof
Technical field
The present invention relates to a kind of preparation method for composite electrode material for super capacitor.
Technical background
The energy is the power of the national economic development, is also the important indicator of weighing national overall national strength, Civilization development degree and living standard.Follow the sharp increase of population and economic developing rapidly, the energy is shortage day by day, and environment comes into one's own day by day, carries out the exploitation of the energy and rationally utilizes the sustainable development that is directly connected to human society, the emphasis of Ye Shi various countries research.Electric energy is being played the part of very important role as a kind of important energy in modern production and life.Energy-storage travelling wave tube is applied to the various aspects of productive life, also more and more higher to the performance requirement of energy-storage travelling wave tube.Although traditional capacitor can provide very large power, its energy density is limited, can not meet actual needs.Along with science and technology and social development, many occasions (as electric automobile) are more and more higher to the requirement of power, also far beyond the ability to bear of current battery simultaneously.Under this background, a kind of novel energy-storage travelling wave tube-" ultracapacitor " is developed rapidly.
Ultracapacitor (Supercapacitor), is also electrochemical capacitor (Electrochemicalacitor), is a kind of energy density and the power density novel energy-storing element between traditional capacitor and battery.It has the features such as the long and serviceability temperature wide ranges of the ratio electric capacity larger than traditional capacitor, the power density larger than storage battery, service life cycle.Ultracapacitor 20th century six the seventies first occur in the U.S., and move towards gradually market in the eighties, because the potential prospect on electric automobile causes concern, and develop rapidly along with the development of electric automobile, become the focus of domestic and international research.Since 1957 (USP, 2800616) Becker has delivered one piece of patent about ultracapacitor, the development of ultracapacitor is constantly weeded out the old and bring forth the new.Nowadays, ultracapacitor oneself be widely used in the power set of memory protect, portable electric appts and oligosaprobic hybrid automobile of Circuits System.It has wide application prospects in the various fields such as hybrid-electric car, mobile phone, microcomputer.
Since 1992, USDOE and United States advanced battery association just started to organize National Laboratory, university and industrial quarters (Maxwell, GE etc.) to release the feasibility study plan of ultracapacitor used for electric vehicle; 2009, the U.S.'s " next generation " battery and electric motor car plan: national energy portion subsidizes 2,400,000,000 dollars, and wherein 1,500,000,000 dollars subsidize battery and the accessory manufacture thereof of the U.S., to improve the circulation volume of battery.2000, Germany formulated " Renewable Energy Law " regulation new forms of energy account for Germany all energy consumptions 50%, German electric automobile is planned at the year two thousand twenty, reaches 1,000,000 electric automobiles and becomes the leader of electric automobile market.1996, European Union started the project of ultracapacitor, and target is development specific energy 6Wh/kg, 8Wh/L, and specific power 1.5kW/kg, 2kW/L, cycle life exceedes the ultracapacitor of 100,000 times.
Electrode material is ultracapacitor core component, and its properity has conclusive effect to the performance of ultracapacitor.Electrode material is divided into four classes: Carbon Materials, metal oxide, high molecular polymer and composite material.
Carbon Materials (active carbon, carbon nano-tube, carbon nanocoils, carbon gel, carbon fiber etc.) is the electrode material that ultracapacitor is conventional, and according to electric double layer theory, the electric double layer capacitance on carbon resistance rod surface is about 20 μ Fcm -2if specific area is 1000m 2g -1, be 200F/g than electric capacity.
In various Carbon Materials, Mesoporous Carbon Materials is owing to having the suitable electrode material as ultracapacitor in larger aperture.Wherein ordered mesoporous Carbon Materials is because its special duct order is conducive to embedding therein of electrolyte ion and deviates to be subject to extensive concern.Take the material with pore structure as template, first carbon precursor is injected in the duct of template, after charing, remove template, a kind of porosu solid material of the structure of pallet repeatedly is just preserved, mesoporous melecular sieves can be controlled pore passage structure and skeleton simultaneously, and the si molecular sieves preparation that can have different pore passage structures by selection has the Mesoporous Carbon Materials of various pore passage structures.There is sucrose in the charcoal source of preparing ordered mesoporous carbon, phenol, formaldehyde resin and furfuryl alcohol.
Due to the electric double layer capacitance that faraday's electric capacity of metal oxide and hydroxides generation produces much larger than active carbon material surface, therefore pseudo capacitance device just progressively replaces double electric layer capacitor becomes the focus of research and development.As RuO 2be subject to common concern owing to thering is very high ratio electric capacity.Although RuO 2specific capacity is up to 760F/g, function admirable aspect capacity and conductivity, but expensive.Because they generally have strong toxicity, environmental pollution is serious again, and the electrode material that people are devoted to find functional, cheap and environmentally safe for this reason substitutes precious metal material.Many achievements in research both domestic and external show: transition metal oxide material can be used as the substitute of metal oxide containing precious metals electrode material.As Conway once pointed out, some transition metal oxides are as MnO x, NiO xand CoO xdeng the chemical property also with metal oxide containing precious metals, all become studied compared with being hopeful to substitute the electrode material of ruthenium.
Research shows, adopt the capacitor of metal oxide/charcoal combination electrode material can bring into play electric double layer and pseudo-capacitance simultaneously, can make full use of electric double layer principle and fake capacitance principle mutually acts synergistically and carries out charge storage, realize the Performance and Cost Modeling of material and coordinate, and there is the new electrode materials of the not available premium properties of unitary electrode material.But, the preparation method based on metal oxide/charcoal combination electrode material capacitor at present, condition is loaded down with trivial details mostly, and metal oxide/charcoal combination electrode material is than electric capacity not high (300F/g left and right) merely, and its performance has much room for improvement.
Recently, some scholar's research metal hydroxides/charcoal combination electrode material, the energy-storage property of finding material has had great breakthrough, trace it to its cause, because fake capacitance or pseudo capacitance are that chemisorbed/desorption that height of formation is reversible or oxidation/reduction reaction produce the electric capacity relevant with electrode charge current potential by electrode surface or the underpotential deposition of active material occurs on the two dimension of body in mutually or accurate two-dimensional space.But owing to lacking free OH in pure metal oxides electrode -so, OH in reaction -migration be restricted, can only electrode/electrolyte interface occur redox, show surface reaction mechanism.In course of reaction, only have a part of metallic atom on oxide grain surface that redox reaction can occur.And contain OH in metal hydroxides/charcoal combination electrode -so, OH in electrochemical reaction -migration unrestricted, can occur in electrode/electrolyte interface and electrode interior, show surface reaction and internal-response mechanism simultaneously.
Due to the architectural characteristic of electrode material for super capacitor, as closely related with preparation technology in granular size, particle diameter distribution and pattern etc., therefore exploring combination electrode material new preparation process has important meaning.At present, the method for preparing electrode material mainly contains coprecipitation, sol-gel process, electrodeposition process and solvent-thermal method etc.
Under solvent heat condition, the character (density, viscosity, peptizaiton) of solvent influences each other, alter a great deal, and differ greatly under its character and usual conditions, accordingly, the dissolving of reactant, disperseed and chemical reactivity improves greatly or strengthens, this just makes reaction at lower temperature, to occur.Material prepared by solvent-thermal method have active good, purity is high, pattern and the advantage such as granular size is controlled, without through high-temperature calcination, can directly synthesize that particle diameter is little, pattern is regular and the electrochemical active material of good dispersion, is conducive to improve its chemical property.
From the above analysis, the ratio electric capacity of Carbon Materials is lower, and the cost of metal oxide containing precious metals is higher, and business application is more difficult, therefore develops synthesis technique simple, and combination electrode material cheaply, is the problem that people extremely pay close attention to.
