ABSTRACT:
The subject of the invention is an anode material of the silicon-carbon composite type, for a lithium cell, having a high mass capacity and good cycling stability. This material is obtained by a preparation method comprising the steps consisting of:a) providing a silicon powder obtained by the plasma-enhanced chemical vapor deposition (PECVD) technique or by CO2laser, the size of the silicon particles being less than 100 nm;b) mixing the silicon powder with a carbon-containing polymer, andc) carrying out the pyrolysis of the mixture.The invention also proposes a lithium cell containing at least one anode the material of which contains the nanocomposite material produced by this method.
