Pr\u00e9sentation g\u00e9n\u00e9rale<\/h2>\n\n\n\n

Pr\u00e9curseur de carbone poreux d\u00e9riv\u00e9 de coques de noix de coco destin\u00e9 aux anodes composites silicium-carbone. Fabriqu\u00e9 par activation \u00e0 la vapeur et lavage selon un proc\u00e9d\u00e9 sp\u00e9cial afin d\u2019obtenir des mat\u00e9riaux poreux d\u2019une plus grande puret\u00e9. Le vaste r\u00e9seau de micropores offre un espace vide id\u00e9al pour l'expansion du nano-silicium, tandis que la distribution granulom\u00e9trique \u00e9troite garantit un rev\u00eatement uniforme de l'\u00e9lectrode sans s\u00e9gr\u00e9gation de la suspension. Convient aux supports de catalyseurs h\u00e9t\u00e9rog\u00e8nes, aux pr\u00e9curseurs d'anodes silicium-carbone et aux syst\u00e8mes de stockage d'\u00e9nergie \u00e9lectrochimique.<\/p>\n\n\n\n

Principaux domaines d'application<\/h2>\n\n\n\n
    \n
  • Anodes en silicium-carbone pour batteries lithium-ion (\u00e9lectronique 3C, groupes motopropulseurs de v\u00e9hicules \u00e9lectriques, stockage sur r\u00e9seau)<\/li>\n\n\n\n
  • Supports de catalyseurs h\u00e9t\u00e9rog\u00e8nes<\/li>\n\n\n\n

    Coh\u00e9rence au niveau des lots<\/h2>\n\n\n\n
      \n
    • La tol\u00e9rance du volume poreux total de \u00b10,03 cm\u00b3\/g \u00e9limine le \" risque li\u00e9 \u00e0 la coh\u00e9rence \" qui entra\u00eene une divergence des courbes de d\u00e9croissance de la capacit\u00e9 cellulaire d'un lot \u00e0 l'autre.<\/li>\n\n\n\n
    • Contamination extr\u00eamement faible : une teneur en cendres inf\u00e9rieure \u00e0 0,3 % et une teneur en mati\u00e8res magn\u00e9tiques inf\u00e9rieure \u00e0 2 ppm emp\u00eachent la d\u00e9composition de l'\u00e9lectrolyte catalys\u00e9e par des m\u00e9taux en traces (Fe, Ni, Cu).<\/li>\n\n\n\n
    • Une cha\u00eene d'approvisionnement \u00e9prouv\u00e9e : les livraisons \u00e0 grande \u00e9chelle aux principaux fabricants d'anodes ont d\u00e9j\u00e0 commenc\u00e9, avec un volume pr\u00e9vu pour 2026 d\u00e9passant les mille tonnes.<\/li>\n\n\n\n
    • Les mati\u00e8res premi\u00e8res issues de la biomasse contribuent \u00e0 la r\u00e9alisation des objectifs en mati\u00e8re d'approvisionnement en mat\u00e9riaux renouvelables.<\/li>\n<\/ul>\n\n\n\n
