  • Nanocomposite material for the anode of a lithium cell
    Patent number: 8062556
    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 CO2 laser, the size of the silicon particles being less than 100 nm; b) mixing the silicon powder with a carbon-containing polymer, and c) 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.
