Abstract
Se describe una capa activa de electrodos que incluye una red de elementos de carbono de gran relación de aspecto (por ejemplo, nanotubos de carbono, conjuntos de nanotubos de carbono, escamas de grafeno o similares) que proporciona un andamio altamente conductivo desde un punto de vista eléctrico que atrapa o enreda el material activo, por lo que de este modo sostiene a la capa; se puede aplicar un tratamiento de superficie a los elementos de carbono de gran relación de aspecto para promover la adhesión al material activo y cualquier capa de electrodos subyacentes que mejore la cohesión general y la estabilidad mecánica de la capa activa; este tratamiento de superficie forma solamente una capa fina (en muchos casos incluso monomolecular) en la red, lo que deja los espacios vacíos grandes que están libres de cualquier material aglutinante al por mayor y por eso pueden llenarse en cambio con material activo; la capa activa resultante se puede formar con una excelente estabilidad mecánica incluso en una gran carga de masa de material activo y gran espesor.
