Abstract: The present invention includes a process for the manufacture of a storage device for electrical energy. The process includes degassing an anode mass and a cathode mass. The anode mass includes a lithium intercalatable carbon in a mixture with one or more of an organic solvent, a supporting electrolyte, a polymer binder and a supporting electrolyte additive. The cathode mass includes a lithium intercalatable heavy metal oxide in a mixture with one or more of an organic solvent, a supporting electrolyte a polymer binder and a supporting electrolyte additive. The cathode mass and the anode mass are applied to current conductors. A separator is disposed between the anode mass and the cathode mass to form a composite. The composite is laminated to form the storage device.

Abstract: According to the invention, a method for the production of battery electrodes and battery electrodes produced with this method are provided, whereby the method comprises the production of compositions of the electrode materials for cathode or anode material and, if required, a separator material, and the extrusion of the electrode material to form the anode or cathode from the electrode material, and is characterized in that the electrode material comprises isocyanate and an aqueous dispersion of a polymer binder which react with one another to form porous structures. By means of the method according to the invention, extremely elastic and, at the same time, mechanically stable battery electrodes are generated that may be utilized in lithium secondary batteries.

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.
