Abstract

An electrochemical cell has at least one positive electrode, at least one negative electrode and at least one separator arranged between the electrodes. At least one of the electrodes includes a first, coarser mesh and a second, finer mesh. The first and the second mesh at least differ in that the first mesh consists of threads having a larger diameter than the threads of which the second mesh consists, and/or in that the first mesh has mesh openings having a larger opening width than the openings of the second mesh. However, both are woven meshes made of monofilaments. The threads of the first and/or the second mesh are coated with an electrically conducting material and serve as current collectors of the at least one electrode.
