| titleOfInvention | Silicon-doped carbon porous composite film of lithium ion battery and preparation method thereof |
| abstract | The invention discloses a silicon-doped carbon porous composite film of a lithium ion battery and a preparation method thereof, the preparation method comprises the steps of firstly oxidizing simple substance silicon, modifying the oxidized simple substance silicon by organic siloxane to obtain modified simple substance silicon, then preparing the silicon-doped carbon composite film by adopting a mixed solution prepared from the simple substance silicon modified by the organic siloxane, a carbon-based polymer, a foaming pore-making agent and an organic solvent, and then preparing the silicon-doped carbon porous composite film by using a method of depositing a carbon nano material on the silicon-doped carbon composite film and subliming and making pores by using a foaming agent through a chemical vapor deposition method by using hydrocarbon as a carbon source and inert gas as carrier gas. When the lithium ion battery cathode material is applied as a lithium ion battery cathode material, the first lithium intercalation capacity is 1027.6mAh/g, the first lithium deintercalation capacity is 997mAh/g, the coulombic efficiency is 97.02 percent, the coulombic efficiency is 91.31 percent after the lithium ion battery cathode material is cycled for 100 times, and the lithium ion battery cathode material shows excellent charge and discharge performance. |
