Description
Technical field
The present invention relates to a kind of preparation methods of carbon based metal double-hydroxide electrode material for super capacitor, and in particular to
Cotton is carbonized by one kind first, recycles the cotton of the nickel cobalt double-hydroxide growth for making to synthesize under hydrothermal condition in the carbonized
On cloth, prepare using carbon cloth as the new method of the double hydroxide electrode material for super capacitor of flexible substrates.
Background technique
The rapid growth of population in the world, economic fast development increase demand of the people to the energy constantly, cause fossil
The energy constantly reduces and the problems such as global warming, thus people there is an urgent need to develop production cleaning, low cost, the efficient energy with
The needs for meeting following low-carbon and sustainable economic development, find green regenerative energy sources and efficient energy-storage system is to solve ring
The important channel of border pollution and energy shortage problem.Supercapacitor is since high with power density, charge/discharge speed is fast, circulation
The features such as service life is long, low in cost and be concerned.By the difference of energy storage mechnism, double layer capacitor and fake capacitance electricity can be divided into
Chemical capacitor.The energy storage of double layer capacitor and release are contacted in electrode material with electrolyte by electrolyte ion
Surface quick absorption/desorption process occurs, redox reaction, the electrode material of double layer capacitor do not occur in the process
More to use the carbon materials such as graphene, carbon nanotube, active carbon, these material sources are wide, excellent electric conductivity, low in cost, ring
It protects but specific capacitance value is lower, constrain their practical applications in supercapacitor.Fake capacitance electrochemical capacitor is then logical
Cross between the material of electrode surface and electrolyte occur Rapid reversible redox reaction and ion doping/go to adulterate
Journey obtains higher capacity.The oxide/hydroxide of transition metal and conducting polymer etc. are with higher due to its
Specific capacitance is typically used as the electrode material of pseudocapacitors.This capacitor has higher capacitance and energy density, but follows simultaneously
The ring service life is not high.To make up two kinds of respective deficiencies of capacitor, usually two kinds of electrode material reasonable combinations are used at composite material
Make electrode.With the continuous improvement of microelectronic component technology, supercapacitor also starts gradually to wearableization, and portability is soft
Property trend development therefore be used as supercapacitor core component electrode material become flexible super capacitor development pass
Key factor.
The most of electrode material reported at present be it is powdered, during electrode is made, people are usually by powder-like
Product are uniformly coated in conductive substrates after mixing with conductive agent and adhesive, but these conductive agents and adhesive will cause " extremely
Surface " is increasing the resistance between collector and electroactive material, is hindering transmission and the electrolyte of electronics in electro-chemical test
The diffusion of ion leads to the decline of the chemical property of active material.Therefore, flexible super capacitor can be in flexible substrates such as sea
Silk floss, carbon cloth directly grow electrode active material on paper and are formed and have flexible electrode material, avoid " dead surface "
It is existing, charge transmission speed is increased, makes material that there is good electric conductivity and cyclical stability.
This patent is to be carbonized into carbon cloth first using cotton as raw material, then make the metal of synthesis double under hydrothermal conditions
Hydroxide is grown directly upon on carbon cloth, this route raw material is from a wealth of sources, environmentally friendly, low in cost and operating method is easy, finally
Prepare with high electrochemical performance using carbon cloth as the double hydroxide electrode material for super capacitor of substrate.
Summary of the invention
Chemical property and satisfactory mechanical property are prepared by flexible substrates of carbon cloth it is an object of the present invention to provide a kind of
Double hydroxide electrode material for super capacitor.Cotton is carbonized by the present invention at 800 DEG C first, then weighs respectively
0.7~1.2g Nickel dichloride hexahydrate, 1.4~2.8g cobalt chloride hexahydrate, two kinds of substances are mixed in a certain ratio, and weigh 2~3g
Hexamethylenetetramine mixes in the deionized water for being dissolved in 50ml with nickel chloride and cobalt chloride, by carbon cloth or by activity processing
Carbon cloth afterwards immerses mixed solution, after stirring 30min, moves into reaction kettle, hydro-thermal reaction 5h at being 100~120 DEG C in temperature,
Be cooled to room temperature to reaction kettle, by carbon cloth washing, vacuum drying, obtain using carbon cloth as the double hydroxide of flexible substrates
Electrode material for super capacitor simultaneously carries out electrochemical property test.
The present invention is characterized in that: using having cotton flexible to be flexible substrates after carbonization, existed using one step hydro thermal method
Nickel cobalt double-hydroxide is directly grown on carbon cloth, by the higher metal hydroxides of theoretical specific capacitance and flexible substrates reasonable combination
It is fabricated to electrode material for super capacitor, does not need to reduce between collector and active material using conductive agent and adhesive
Resistance, the three-dimensional structure of carbon cloth also promotes the transfer of electronics, and electrode material material is in chemical property with higher
There is good mechanical performance simultaneously.
