A method of making an electrode for a device operating according to galvanic principles, in particular a lithium-ion cell, comprises the steps of: (i) making a sheet-like electrode (2), (ii) detecting where one or more imperfections (4, 4′, 4″) exist on said sheet-like electrode, and (iii) with respect to a respectively detected imperfection (4, 4′, 4″), correcting a surrounding area (6, 6′) of the imperfection (4, 4′, 4″) including said imperfection. Based on the result of detection step (ii), at least a portion (8, 8′, 8″) of the laminar electrode may be provided that has no imperfection. In an electrode made according to the method, in particular cathode or anode, for a device operating according to galvanic principles, in particular a lithium-ion cell comprising an electrode material that is arranged in a sheet-like manner, the electrode material is composed of at least a first, in particular slat-like portion (22-1), which is free from imperfections, and a second, in particular slat-like portion (22-2), which is free from imperfections. A device operating according to galvanic principles, in particular a lithium-ion cell, comprises the following layers, which are arranged one upon the other: a first electrode (32), which is free from imperfections, which comprises at least two assembled portions, which are free from imperfections, a separator layer (50) comprising a separator material (16) that is developed in a sheet-like manner, and a second electrode, which is free from imperfections, which consists of a one-piece portion or which comprises at least two assembled portions, which are free from imperfections, and which is complementary to the first electrode.
