Abstract

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.
