| titleOfInvention | Preparation method of carbon-coated tin dioxide superfine powder lithium ion battery negative electrode material |
| abstract | The invention discloses a preparation method of a carbon-coated tin dioxide superfine powder lithium ion battery negative electrode material. The preparation method comprises the following steps of: dissolving the precursor of tin and long-chain fatty acid in a high boiling point solvent under certain condition; continuously blowing in air at 200 DEG C-280 DEG C to prepare a tin dioxide nanocrystal which is high in degree of crystallinity and monodisperse; and recycling, purifying, roasting in a nitrogen gas atmosphere to obtain carbon-coated tin dioxide superfine powder. According to the preparation method disclosed by the invention, dimension of the carbon-coated tin dioxide superfine powder can be adjusted by controlling factors of reaction temperature, time, and the like. The carbon-coated tin dioxide superfine powder prepared by the preparation method disclosed by the invention has characteristics of high capacity (as high as 1000 mAh.g<-1>), stable capacity (battery capacity of 480 mAh.g<-1> during 8C discharging) under high-rate discharge condition, and the like. |
