Description
Technical field
The present invention relates to a kind of preparation method of anode material of lithium-ion battery, in particular to a kind of cotton base multiporous biological
The preparation method of matter carbon.
Background technique
The concept of sodium-ion battery (SIB) was proposed in the 1970-1980 age, parallel with lithium ion battery (LIB).With
Afterwards, then LIB has conducted extensive research in 1991 by Sony's successful commercialization to develop LIB.However, the research about SIB
It almost without carrying out, or even has lain on the table 30 years, so that almost being disappeared to energy storage with the research of sodium insertion material.
Recently, it is related to various consumer electronics products, the booming of numerous electrical equipments of electric tool and electric car results in
The wilderness demand of LIB, this may be by the obstruction of limited lithium resource deposit (20 ppm in earth cluster).In consideration of it, research
Personnel pay close attention to SIB again, because being rich in sodium resource (23600 ppm).In addition, Na element is adjacent with Li in alkalinous metal group,
They just have many similar physicochemical properties in this way.Therefore, when effectively solving the problems, such as some, SIB can replicate LIB at
Function.Not surprisingly, the electrochemical principle of SIB is similar to the electrochemical principle of LIB, during the charging process, Na+It is extracted from anode
And cathode is moved to react with negative electrode material.Upon discharging, opposite process occurs, extracts Na from cathode+And it moves to just
Pole is to return to original state, this is along with the electronics transfer in external circuit to provide electric energy.
Compared with LIB, SIB has the following characteristics that (1) sodium stock number is abundant, cheap；(2) SIB allows using low
The electrolyte of concentration, to reduce costs；(3) Na+Not forming alloy with aluminium, aluminium foil can be used as collector in cathode,
It further reduces the cost and weight；(4) SIB allows to discharge into zero volt without over-discharge electrical characteristics.Negative electrode material restricts at present
Key factor.The disadvantages of SIB negative electrode material is not high poor with long circulating performance presently, there are first charge-discharge efficiency, therefore develop
Novel SIB negative electrode material with high first effect and good cycling stability is extremely urgent.
Since sodium ion atomic radius is big bigger than lithium ion, limited by graphite layers away from smaller (0.34 nm), sodium ion
It is difficult to be embedded into graphite layers away from.Hard carbon has many advantages as SIB negative electrode material, than conventional graphite electrodes material.Firmly
Carbon-coating spacing is larger, and loose porous and interlaced class graphite laminate structure can store a large amount of sodium ion.Selection is suitable
Presoma it is particularly important to synthesize hard carbon.
Biomass resource is abundant, and carbon rich in largely belongs to renewable resource, the carbon material prepared with it
Cause the common concern of countries in the world researcher by the advantages that its preferable electric conductivity, high-specific surface area, while its is green
The features such as color, sustainable, cheap, widely distributed, collection are easy, offers convenience to industrialization large-scale production.In addition, raw
The carbon material of substance raw material preparation also reflects the theory of Green Chemistry.Cotton, as one of most common crops, at me
State plants extensively, cheap and easy to get, the cellulose containing 90 % or more, it is converted to multiporous biological carbon by carbonization, is used for SIB
Negative electrode material, be of great significance for solving current energy crisis and problem of environmental pollution.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation process is simple, raw material is easy to get, environmental-friendly, and makes to produce
The preparation method of cotton Quito hole biomass carbon of object BET surface area with higher.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of preparation side of cotton Quito hole biomass carbon
Method, innovative point are: the preparation method includes the following steps:
Step 1: taking the cotton of certain part by weight to clean up, dry, obtain product A；
Step 2: product A and metal chloride are obtained into product B than mixed grinding by certain mass；
Step 3: product B being laid in aluminium oxide porcelain boat, is placed in the tube furnace of inert atmosphere, with certain heating rate liter
Temperature obtains product C to high temperature cabonization is carried out at 800~1300 DEG C；
Step 4: product C being soaked in hydrochloric acid solution, product D is obtained；
Step 5: product D is washed repeatedly with water to pH=7, vacuum drying at 60 DEG C, obtain cotton Quito hole biomass carbon materials
Material.
Further, it cleans and is adopted wash with distilled water in the step 1.
Further, stoving process is the first heating rate heating with 1~3 DEG C/min in the step 1, then with 4~6
DEG C/heating of the heating rate of min, it is warming up to 60~80 DEG C and carries out freeze-day with constant temperature again.
Further, the metal chloride in the step 2 be zinc chloride, iron chloride, potassium chloride, in sodium chloride at least
It is a kind of.
Further, in the step 2 product A and metal chloride mass ratio 1:2~5.
Further, the milling time in the step 2 is 30~60 min.
Further, heating rate is 2~5 DEG C/min in the step 3, and the high temperature cabonization time is 2~3 h.
