Abstract: A cutting method is disclosed for cutting a continuous separator sheet material in a cutting zone comprised between two non-rectangular electrodes using a laser arrangement of solid state type, executing on the material a first cutting line that is then intersected by a second cutting line at an intersection point located in an intermediate portion of the first cutting line, with an intersection direction that is perpendicular to the first cutting line at the intersection point.

Abstract: There is described a laminating apparatus for coupling electrodes of non-rectangular shape with a separating film for the manufacture of electric energy accumulating devices, wherein a pair of laminating rollers has a roller driven by an elastic arrangement loaded with a variable force adjusted by an endless screw conveyor controlled by a brushless motor, during the passage of the electrodes, so as to vary the laminating force according to the width of the electrode laminated instant by instant, in order for the laminating pressure to remain almost constant.

Abstract: The invention relates to a method for forming a monocell or a bi-cell for a lithium-ion electric energy accumulating device, wherein it is provided to first laminate, in a first laminating unit, a first arrangement comprising a first electrode and two separating elements, so as to obtain a multilayered laminated element. In the first arrangement, the electrode is interposed between the two separating elements without yet being laminated to either of the two separating elements. The method then provides to form a second arrangement comprising the multilayered laminated element and a second electrode. The method finally provides to laminate the second arrangement in a second laminating unit, so as to obtain the cell.
