Abstract: Separators for lithium-polymer batteries and methods for their production are described. One separator has the capability of preventing meltdown and short-circuit in the event of overheating an overvoltage. One separator is a dual-component fabric based on glass fibers and polymer fibers and comprises micropores for impregnation. One such fabric has a thickness of 2 through 15 ?m and is used as an intermediate layer between anode and cathode; applications of absorber additives such as magnesium oxide or magnesium carbonate improve the effectiveness of the separator.

Abstract: A process for the production of a lithium polymer cell is involves extruding a material mixture for an anode and a mixture for a cathode to form an anode and cathode masses. At least one of the masses is extruded with a mixture of cyclohexanone and methyl ethyl ketone. The anode and cathode masses are laminated onto conductors and joined with an intervening separator to form a lithium polymer cell.

Abstract: Electrodes for high energy lithium polymer batteries are produced. An electrode material mixture of a Li-intercalatable active electrode material, a supporting electrolyte and a solvent is mixed with a binder. Homogenization of the mixture results in a single phase suspension electrode mass which is applied to a conductor to form a homogeneous coating thereon. The electrode mass is adjusted to the desired thickness after drying.
