【 摘 要 】

Lithium ion batteries with the advantages of the long cycle life, high energy density, high power density etc. have been widely used in mobile phones, notebook computers and other areas of the power. The SiO is one of the most promising materials of lithium ion battery cathode material because of the theoretical specific capacity more than graphite 10 times. While traditional method, the chemical vapor deposition method has been unable to meet the increasing demand for the SiO material. In this paper, the SiO powders have been synthesized by a new method which is named Crucible Rotating Up method. The technological process of this method has been introduced in this paper and the X-ray diffraction analysis and SEM-EDS have been performed for the test samples. The result shows that the high purity SiO gas has been generated in the Crucible Rotating Up Furnace.
