Abstract
The invention relates to a cheap and fast method for the production of electrode/current collector laminates, the electrode layer having a thickness of at least 20 &mgr;m. The current collector foil is provided with an electrode paste coating on at least one of its sides by filling paste into the cells or grooves of a patterned matrice roll; transferring paste from the matrice roll onto the current collector foil by a printing operation involving contacting the matrice roll and the current collector foil or alternatively contacting the matrice roll with an offset roll which in turn is in contact with the current collector foil; drying the layer of paste printed onto the current collector; and optionally repeating the process until the desired thickness of the electrode layer is obtained. The invention also relates to a gravure roll and a primer-coated current collector foil for use in the method, a primer paste for the production of primer-coated current collector foils and an electrode paste for the production of electrode/current collector laminates.
