Description

A kind of preparation method of tin ash/carbon negative pole material
Technical field
The present invention relates to technical field of lithium ion, and in particular to a kind of preparation method of tin ash/carbon negative pole material.
Background technology
Electrode material is the key of lithium ion battery.At present, commercialized lithium ion battery negative material is mainly graphite, graphite cost is low, wide material sources, suitable for commercialization, but can form SEI films after the embedding lithium of graphite, cause the irreversible loss of initial capacity, make its capacity relatively low, theoretical capacity is only 372 mAh/g, the application in the field for needing high-energy output is restricted.And Carbon anode current potential and lithium metal current potential closely, the easy precipitating metal lithium in Carbon anode surface formation Li dendrite causes battery short circuit, there is certain potential safety hazard.Metal oxide such as Fe2O3, SnO2There is very high specific capacity Deng as lithium ion battery negative material.Wherein SnO2Specific capacity is up to 782 mAh/g, but SnO2As electrode material, Volume Changes are up to 200~300% in charge and discharge process, and this can cause the efflorescence of electrode, cause the open circuit of active material and collector.Therefore, most of SnO2All there is the problem of capacity attenuation is rapid in electrode, the development as lithium ion battery negative material and practical application which also limits metal oxide.Therefore, researchers are conducted in-depth research to this, including being coated to material, doping vario-property, it is prepared into compound or nano material etc., the performance of electrode material is improved by these methods, particularly metal oxide carries out the compound of nanoscale with Carbon Materials, prepares new nanostructured and has become the focus studied at present.
The content of the invention
Regarding the issue above, the present invention provides a kind of preparation method of tin ash/carbon negative pole material.
The technical scheme for realizing the object of the invention is：
A kind of preparation method of tin ash/carbon negative pole material, comprises the following steps：
（1）By Tin tetrachloride pentahydrate：Citric acid：Glucose or sucrose are 2：0.5：0.5~1 mass ratio is weighed, and citric acid and glucose are added in 30-50 ml deionized waters, stirred to clarify, solution A is formed；
（2）In the deionized water that Tin tetrachloride pentahydrate is added to 50 milliliters, stirring forms tin chloride solution B；
（3）Under agitation, toward solution A is slowly dropped into tin chloride solution B, continuing stirring makes solution form uniform suspension, is put into baking oven and is heated to 120 DEG C, is incubated 6 hours, obtains sediment；
（4）Sediment is centrifuged with ethanol and deionized water, cleaned, is dried, then is calcined under argon gas protection, that is, obtains tin ash/carbon negative pole material.
The temperature of the calcining is 300 to 500 DEG C, and calcination time is 3 to 5 hours.
Advantages of the present invention is：Preparation technology of the present invention is simple, is not introduced into strong acid and strong base or other noxious materials, employs the route of green syt, and prepared tin ash/carbon negative pole material cycle performance is good, and specific capacity is high.
