The present invention provides a method for applying an electrically conductive coating on at least a portion of a sheet-like component of an electrochemical (EC) cell. The method comprises providing an electrically conductive material having a flowable consistency and applying it on the sheet- like component while creating a shearing stress in the electrically conductive material to form the coating. The invention also concerns an apparatus capable of implementing the method. Finally, the invention relates to a lithium electrochemical cell in which a protective coating is applied between the cathode and the cathode current collector, the coating comprising a potassium- based soluble compound and a conductive additive.
L'invention concerne un procédé d'application d'un revêtement électriquement conducteur sur au moins une partie d'un composant sous forme de feuille d'une cellule électrochimique (EC). Ce procédé consiste à produire un matériau électriquement conducteur possédant une consistance fluide et l'appliquer sur le composant sous forme de feuille tout en créant une contrainte de cisaillement dans le matériau électriquement conducteur afin de former le revêtement. L'invention concerne également un appareil permettant de mettre en oeuvre ce procédé.
