Abstract
The electrode assembly comprises electrodes (2, 3) in the form of coated foils, wherein at least one of said electrodes is folded along one or more folding lines (15a-15d, 35), and wherein said at least one electrode comprises one or more arrays of apertures (21) arranged respectively along said one or more folding lines. The apertures are configured in terms of their shape, number and dimensions so that stress buildup in the vicinity of the folding lines is mitigated, thereby reducing the risk of rupturing and / or breaking the foils and the coatings provided thereon.
