Modified silicon monoxide material for use in negative electrode of lithium-ion battery and preparation method therefor |
| abstract |
Disclosed are a modified silicon monoxide material and a preparation method therefor. The modified silicon monoxide material is for use in a negative electrode of a lithium-ion battery. The modified silicon monoxide material is prepared by reacting raw silicon, silicon dioxide and a metal silicate under high temperature conditions and in a vacuum so as to generate silicon monoxide; allowing the resulting metal vapor and silicon monoxide to react during the preparation process so that the metal silicate is incorporated in situ into the silicon monoxide, whereby silicon-containing particles are formed wherein metal silicate is evenly dispersed around the silicon and the silicon monoxide; and coating a surface of the silicon-containing particles with a carbon material. The modified silicon monoxide material of the present invention comprises a silicate evenly dispersed therein and a carbon material evenly coated thereon, and when used in a negative electrode of lithium-ion battery, provides a high specific capacity, a high initial coulombic efficiency, and excellent cycling performance and rate performance. In addition, the preparation method of the present invention employs inexpensive raw materials, which facilitates industrialization of the preparation method and enables wide use of the modified silicon monoxide material. |
