PROCEDE DE FABRICATION D'UNE ELECTRODE POUR ACCUMULATEUR AU LITHIUM ET ELECTRODE ASSOCIEE. |
摘要 |
A method for producing an electrode comprising a core-shell nanocomposite material of which the core is made from silicon and the shell from carbon is provided. The method includes A) synthesising the nanocomposite material by pyrolysing a silicon core to form a core and then pyrolysing a carbon shell precursor to form a carbon shell around the core, wherein the quantities of silicon and carbon precursor are injected in a proportion such that the mass percentage of carbon in the nanocomposite material is greater than or equal to 45%; B) dispersing the nanocomposite material synthesised in step A) in a solvent to form an ink; C) applying this ink to a support intended to form an electricity collector; D) eliminating the solvent from the ink applied to the support in step C) to obtain the electrode; E) pressing or calendaring the electrode. |
