Layer electrode for electro-chemical components and electrochemical double layer capacitor having said layer electrode

Abstract

The invention concerns a layer electrode ( 6 ) for electrochemical components with a plurality of fibers ( 1 ) that all run in parallel with one another in a preferred direction at least in sections, in that the fibers ( 1 ) are connected with one another via bonding. The bonding of the fibers ( 1 ) can be produced via piercing the layer electrodes ( 6 ) with harpoons or also via sewing. The inventive layer electrodes ( 6 ) have the advantage that they can be produced thin and cost-effectively. Furthermore, the invention specifies a capacitor with the inventive layer electrode ( 6 ).
