CA 2388711
An electrode for a lithium cell having an active material thin film absorbing/desorbing lithium such as a microcrystalline silicon thin film or an amorphous silicon thin film provided on a current collector, characterized in that the thin film is divided by cut in the direction of the thickness into columns, and the bottom of each column is in close contact with the current collector.
L'invention concerne une électrode pour pile au lithium présentant une couche mince de matière active absorbant/désorbant du lithium telle qu'une couche mince de silicium microcristallin ou une couche mince de silicium amorphe placée sur un collecteur de courant, caractérisée en ce que la couche mince est divisée par découpage en colonnes dans le sens de l'épaisseur, et en ce que le base de chaque colonne se trouve en contact étroit avec le collecteur de courant.
