Electrodes for an electric device operating according to galvanic principles, such as a lithium-ion cell, and method for its manufacture

摘要

The method involves detecting whether multiple fault spots (4, 4', 4'') are provided on a laminar electrode (2). A surrounding area of the fault spots, and the fault spots are removed from the laminar electrode. An electrical resistance of a strip shaped area (10) of the laminar electrode is measured. A dielectric capacitance of the strip shaped area of the laminar electrode found in a measuring window (28) is measured. A layer of electrode material e.g. anode material, is applied on a metal foil e.g. aluminum foil and copper foil. An independent claim is also included for an electrode that is manufactured using the method.
