Descripci\u00f3n general<\/h2>\n\n\n\n

Precursor de carbono poroso derivado de la c\u00e1scara de coco para \u00e1nodos compuestos de silicio-carbono. Se fabrica mediante activaci\u00f3n con vapor y un proceso especial de lavado para obtener materiales porosos de mayor pureza. La extensa red de microporos proporciona el espacio vac\u00edo ideal para la expansi\u00f3n del nanosilicio, mientras que la distribuci\u00f3n estrecha del tama\u00f1o de las part\u00edculas garantiza un recubrimiento uniforme del electrodo sin segregaci\u00f3n de la suspensi\u00f3n. Adecuado para portadores de catalizadores heterog\u00e9neos, precursores de \u00e1nodos de silicio-carbono y sistemas de almacenamiento de energ\u00eda electroqu\u00edmica.<\/p>\n\n\n\n

\u00c1reas clave de aplicaci\u00f3n<\/h2>\n\n\n\n
    \n
  • \u00c1nodos de silicio-carbono para bater\u00edas de iones de litio (electr\u00f3nica 3C, sistemas de propulsi\u00f3n de veh\u00edculos el\u00e9ctricos, almacenamiento en la red el\u00e9ctrica)<\/li>\n\n\n\n
  • Soportes de catalizadores heterog\u00e9neos<\/li>\n\n\n\n
  • Nuevos campos de la energ\u00eda y la electroqu\u00edmica<\/li>\n<\/ul>\n\n\n\n

    Consistencia a nivel de lote<\/h2>\n\n\n\n
      \n
    • La tolerancia del volumen total de poros de \u00b10,03 cm\u00b3\/g elimina el \"riesgo de inconsistencia\" que provoca que las curvas de disminuci\u00f3n de la capacidad celular divergan entre lotes.<\/li>\n\n\n\n
    • Contaminaci\u00f3n ultrabaja: un contenido de cenizas inferior a 0,3% y de material magn\u00e9tico inferior a 2 ppm evitan la descomposici\u00f3n del electrolito catalizada por metales traza (Fe, Ni, Cu).<\/li>\n\n\n\n
    • Cadena de suministro comprobada: ya se est\u00e1n realizando env\u00edos masivos a fabricantes de \u00e1nodos de primer nivel, con un volumen que superar\u00e1 las mil toneladas en 2026.<\/li>\n\n\n\n
    • Las materias primas derivadas de la biomasa contribuyen a alcanzar los objetivos de abastecimiento de materiales renovables.<\/li>\n<\/ul>\n\n\n\n
