PROCEDE DE PREPARATION D'UN MATERIAU COMPOSITE SILICIUM/ CARBONE, MATERIAU AINSI PREPARE ET ELECTRODE NOTAMMENT ELECTRODE NEGATIVE, COMPRENANT CE MATERIAU. |
摘要 |
Process for preparing composite silicon/carbon material composed of carbon-coated silicon particles, wherein the following successive steps are carried out: silicon particles are mixed with a solution of an oxygen-free polymer in a solvent, whereby a dispersion of silicon particles in the polymer solution is obtained; the dispersion obtained in step a) is subjected to a spray-drying operation whereby a composite silicon/polymer material consisting of silicon particles coated with the polymer is obtained; the material obtained in step a) is pyrolyzed whereby the composite silicon/carbon material composed of carbon-coated silicon particles is obtained. |
