摘要： Visibility packaging for energy storage elements includes a front wall spaced apart from a rear wall and provided with at least one viewing cutout and at least one web having a central apex region fixed to a contact region of the rear wall, wherein the web and the rear wall together form a K-shaped cross section in a closure position and the web closes a removal opening of a receiving space, and the rear wall has at least one perforation that delimits a contact region from a remainder of the rear wall and makes it possible to separate the contact region from the rear wall such that the web can be transferred by a folding operation into a removal position in which the apex region of the web is spaced apart from the rear wall and the web frees the removal opening of the receiving space.

摘要： A method for producing a component of an electrochemical cell includes applying at least one layer of an electrode material to a strip-shaped current collector passing through a coating apparatus such that the current collector, after passing through the coating apparatus, comprises one or more coated strip-shaped sections oriented in a longitudinal direction and being coated with electrode material and one or more uncoated strip-shaped sections oriented in the longitudinal direction. The method further includes assigning a respective uncoated strip-shaped section of the one or more uncoated strip-shaped sections a machine-readable coding that identifies the respective uncoated strip-shaped section. The machine-readable coding is assigned in the form of through holes into the respective uncoated strip-shaped section, or the coding is applied onto the respective uncoated strip-shaped section.

摘要： A lithium-ion secondary electrochemical cell includes a negative electrode formed as a composite electrode comprising an anode current collector and a first electrochemically active component capable of intercalating and deintercalating lithium ions. The lithium-ion electrochemical cell further includes a positive electrode formed as a composite electrode comprising a cathode current collector and a second electrochemically active component capable of intercalating and deintercalating lithium ions. The lithium-ion electrochemical cell also includes a lithium reserve formed at a current collector reserve region that is at least partly free of the first and the second electrochemically active components, the current collector reserve region being a portion of the anode current collector and/or the cathode current collector.

摘要： A method for producing a button cell includes providing a metal cell cup, providing a metal cell top, and providing a first electrode and a second electrode. The first electrode includes a first current collector partially coated with a first active electrode material and having an active material-free region. The second electrode includes a second current collector partially coated with a second active electrode material and having an active material-free region. The method further includes attaching a first metal foil conductor to the active material-free region of the first current collector, attaching a second metal foil conductor to the active material-free region of the second current collector, and forming a cylindrical electrode winding by winding, in a spiral, an electrode assembly. The first and second metal foil conductors extend out of the cylindrical electrode winding from first and second end faces of the cylindrical electrode winding.
