摘要： A process of co-extrusion of a thin electrode sheet with a thin electrolyte polymer sheet directly onto a current collector sheet for a lithium polymer battery. The process includes the steps of: (a) mixing a polymer with active electrode material, lithium salt and electronic conductive material in a first mixing chamber to form an electrode slurry; (b) mixing a polymer with a lithium salt in a second mixing chamber to form an electrolyte slurry; (c) feeding the electrode slurry through a first flow channel and the electrolyte slurry through a second flow channel; (d) extruding the electrode slurry in the form of a thin electrode sheet through a first die opening connected to the first flow channel, the electrode slurry being extruded directly onto a current collector sheet; and (e) concurrently extruding the electrolyte slurry in the form of a thin electrolyte sheet through a second die opening adjacent to the first die opening and connected to the second flow channel, the thin electrolyte sheet being extruded directly onto the thin electrode sheet.

摘要： A process for extruding a thin positive electrode sheet having at least 40%/wt of solid content for a lithium polymer battery through a single or twin screw extruder is disclosed as well as a positive electrode sheet produced therefrom. A mixture of active cathodic intercalation material, lithium salt and electronic conductive material is mixed with a polymer of the polyether family in a ratio of at least 40% of total weight into the mixing chamber of an extrusion machine and extruded through a classical sheet die into a thin cathode sheet or film onto a substrate in sheet form.

摘要： A process for laminating at least one electrode sheet onto an electrically conductive support film is provided. The process comprises heating the electrically conductive support film and laminating the at least one electrode sheet onto at least one side of the heated electrically conductive support film. An apparatus for laminating at least one electrode sheet onto an electrically conductive support film is also provided. The apparatus comprises lamination rollers forming a nip and means for carrying the electrically conductive support film and the at least one electrode sheet to the nip formed by the lamination rollers. The apparatus also comprises a heater for heating the electrically conductive support film before the electrically conductive support film reaches the nip formed by the lamination rollers.
