State technical problem, technical solution proposed by the present invention are as follows:
A kind of preparation method for the carbon nanofiber electrode material loading nickel nickel, comprising the following steps:
(1) it disperses nanometer wood fibre in ultrapure water, nanometer wood fibre film is dried to obtain after vacuum filtration；It receives
Rice wood fibre has good film forming, dry because drainage weightlessness makes its fiber self assembly form a film during suction filtration
After can obtain film flexible；
(2) nanometer wood fibre film obtained in step (1) is placed in nickel salt solution after impregnating and takes out drying, then is high
Warm carbonization treatment obtains nickel carbon nano-fiber film material；When high temperature cabonization, nickel ion can be reduced into nickel simple substance；
(3) by nickel carbon nano-fiber film material obtained in step (2) by electroxidation handle i.e. obtain nickel-loaded/
The carbon nanofiber electrode material of nickel oxide；The effect of electroxidation processing is that elemental nickel is oxidized to nickel oxide, increases material
Capacitive property.
In above-mentioned preparation method, needs that nanometer wood fibre is first prepared into form of film and is soaked in nickel salt solution again,
If nanometer wood fibre first impregnates absorption nickel ion, it is difficult to make nickel ion be attached to nanometer wood fibre in the form of filtering
It goes up and forms a film, because nickel ion is dissolved in water, be easy to take away with water during suction filtration, even if there are part of nickel ionic adsorption, point
Cloth also can be uneven.Absorption can solve the problems such as absorption is uneven, load capacity is not high, while side after experimental study shows film forming
Method is simple and easy.
In above-mentioned preparation method, it is preferred that the nanometer wood fibre passes through sour water solution-high pressure homogenization method by cellulose powder
It is prepared；Nickel salt in the nickel salt solution is at least one of six water nickel chlorides, nickel sulfate hexahydrate or six water nickel nitrates.
In above-mentioned preparation method, it is preferred that control is carried on nanometer wood fibre film when impregnating in the step (2)
The quality of nickel salt account for the 10%-70% of nickel carbon nano-fiber film material gross mass, it is furthermore preferred that being 30-60%.Nickel salt
Load capacity have a large effect to the performance of subsequent electrode material, the load capacity of nickel salt needs to control preferred control and is
The chemical property of 30-60%, electrode material are optimal.
In above-mentioned preparation method, it is preferred that control nanometer wood fibre when dispersing nanometer wood fibre in ultrapure water
The mass concentration of solution is 0.5-0.8wt.%.The mass concentration of nanometer wood fibre has the porosity of the film of formation biggish
It influences, the control of above-mentioned mass concentration and the control of high temperature cabonization cooperate, the available optimal electrode material of chemical property
Material.
In above-mentioned preparation method, it is preferred that the high temperature cabonization processing carries out in tube furnace, under nitrogen protection, and
Keeping carburizing temperature is 450-1000 DEG C, and heating rate is 5-10 DEG C/min, soaking time 1-3h.The technique of carbonization treatment is joined
The hole result tool of several pairs of electrode materials has a certain impact, and the determination of above-mentioned high temperature cabonization temperature is conducive to obtain electrochemistry
The excellent electrode material of energy.
In above-mentioned preparation method, it is preferred that the electroxidation processing is electric for nickel carbon nano-fiber film material is placed in three
It in polar body system, then is handled using potentiostatic method, the potassium hydroxide solution (1mol/L or 6mol/L) that electrolyte uses when processing,
Control voltage is 0.8-1.2V, and sensitivity (sensitivity) is set as 1.0e-1, the processing time is 30-600s (preferred
For 300-600s).The control of the technological parameter of above-mentioned electroxidation processing is very big on electrode performance influence, electroxidation processing parameter
