Patent

CA 2231482

The invention relates to a laminated lithium-ion cell which comprises flexible layers, wherein the negative electrode is lithium metal, lithium alloy or a metallic bonded fiber web or a foam, which comprises a lithium-intercalating material such as carbon, graphite, tungsten dioxide, molybdenum dioxide, titanium dioxide, titanium disulfide or vanadium pentoxide as the active component, the separator is made of a porous polymer in which a non-aqueous electrolyte is immobilized, and the positive electrode as the active material comprises lithiated manganese dioxide, manganese spinel, lithium-metal oxides, lithium-metal mixed oxides or lithium-metal sulfides.

Cellule stratifiée lithium-ion comportant des couches souples dans lesquelles l'électrode négative est faite de lithium métallique, d'alliage de lithium ou d'une toile ou d'une mousse liée à du métal, comportant, entre les couches de lithium, une matière intercalante comme le carbone, le graphite, le dioxyde de tungstène, le dioxyde de molybdène, le dioxyde de titane, le disulfure de titane ou le pentoxyde de vanadium comme matière active, et un séparateur constitué de polymère poreux dans lequel est fixé un électrolyte non aqueux, et dont l'électrode positive comporte, comme matière active, du dioxyde de manganèse lithié, de la spinelle au manganèse, du lithium - oxyde métallique, du lithium - oxydes mixtes de métal ou du lithium - sulfures de lithium.
