Abstract: 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.

Abstract: The invention provides a pre-mix of positive electrode material in transportable solid form comprising polymer and solid particles of electrochemically active material and/or electronically conductive additives and a process for preparing a pre-mix positive electrode in transportable solid form. The pre-mix positive electrode material may also comprise an alkali metal salt either dissolved or dispersed in the mixture. The invention also provides making a cathode film from the transportable solid pre-mix of positive electrode material.

Abstract: A material for solid polymer electrolyte, made of a polyether polymer having a moisture content in the range of 400 to 5,000 ppm by weight. A formed solid polymer electrolyte, which is made by mixing the material for solid polymer electrolyte together with an electrolyte salt compound soluble in the polyether polymer, has good ionic conductivity and high mechanical strength. A polyether polymer having a moisture content not larger than 0.04% by weight and a toluene-insoluble content not larger than 5% by weight. This polyether polymer gives a formed solid polymer electrolyte having a smooth surface.

Abstract: 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.

Abstract: 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.
