Title (EN) LITHIUM SECONDARY CELL AND METHOD FOR MANUFACTURE THEREOF
(FR) PILE SECONDAIRE AU LITHIUM ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A lithium secondary cell having a negative electrode comprising a lithium metal or alloy formed on an electrically conductive substrate by vacuum film forming, characterized in that a hydrophobic material layer is formed on the surface of a lithium metal or alloy, or an amorphous lithium metal or alloy formed on the substrate; and a method for manufacturing the lithium secondary cell. The cell is free from the formation of dendrites and exhibits good cycle life.
(FR)Pile secondaire au lithium possédant une électrode négative composée de lithium ou d'un alliage de lithium créée sur un substrat électriquement conducteur par constitution d'un film sous vide. Procédé consistant à créer une couche de matériau hydrophobe sur la surface de lithium ou d'un alliage de lithium ou à créer une couche de lithium amorphe ou d'alliage de lithium sur le substrat et procédé servant à fabriquer une pile secondaire au lithium. Cette pile est exempte de dendrites et possède une durée de vie excellente.
