Description

The preparation method of anode material for lithium-ion batteries
Technical field
The present invention relates to a kind of preparation method's of cell positive material, particularly anode material for lithium-ion batteries preparation method.
Background technology
Lithium ion battery has been widely used in portable set and memory support circuit because of its voltage height, advantage such as volume is little, the life-span is long, security performance is good, pollution-free, becomes market prospects a kind of secondary cell best, with fastest developing speed.The battery characteristics of lithium ion battery and price depend primarily on its positive electrode.That at present, research is maximum is the transition metal oxide positive electrode of three kinds of rich lithiums: LiCoO 2, LiNiO 2And LiMn 2O 4They have shown pluses and minuses separately in research and development, and the cost costliness is the common problem of lithium ion battery, is not effectively solved for a long time.The preparation of above-mentioned several rich lithium transition-metal oxide positive electrodes all need be finished under oxygen atmosphere, technology cost height.Low-cost preparation LiNi under air atmosphere xCo 1-xO 2The research of high performance lithium ion battery anode material yet there are no report.
Summary of the invention
It is low that purpose of the present invention just provides a kind of cost, prepares LiNi under air atmosphere xCo 1-xO 2The method of anode material for lithium-ion batteries.
The present invention adopts the liquid phase synthetic technology, at first with Ni (NO 3) 26H 2O and Co (OH) 2Be raw material, synthetic Ni xCo 1-x(OH) 2Presoma evenly distributes Co and Ni, forms substitutional solid solution.Utilizing between presoma and end product has structural similarity, adopts topological growth response mechanism and solid phase reaction synthetic technology, with Ni xCo 1-x(OH) 2And LiOHH 2O has avoided oxynitrides and CO in the general calcination process for the initial thing of calcining xGeneration, above-mentioned synthesis and preparation process can be carried out under air atmosphere, be a kind of brand-new green material building-up process.
Concrete steps are as follows:
(1) presoma Ni xC0 1-x(OH) 2Preparation;
(2) presoma and LiOHH 2The O ball milling mixes;
(3) with the uniform sample briquetting of mixed grinding;
(4) by certain heat treating regime, carry out solid phase reaction.
Technology cost of the present invention is low, does not require harsh oxygen atmosphere, and synthesis condition is simple, and raw material cheaply is easy to get.The anode material for lithium-ion batteries of preparation has good architectural feature and good electrochemical, can be widely used in portable set and memory support circuit.
