Nanocomposite material for lithium secondary battery

摘要

The method involves providing silicon powder obtained by a plasma enhanced chemical vapor deposition technique or by carbon dioxide laser, where the size of the silicon particles is lesser than one hundred nanometers. The powder is mixed with a carbon polymer, and a solvent dissolving the carbon polymer is added to the mixture, where the solvent is propylene oxide and the carbon polymer is polyvinyl chloride. The mixture is maintained under mechanical agitation until the evaporation of the solvent, and pyrolysis of the mixture is performed.
