The energy storage element also includes first and second contact sheet metal members in direct contact with the free edge strips. The cathode and the anode are separated by a separator or a solid electrolyte layer and are arranged relative to one another such that one free edge strip protrudes from one side of an assembly including the cathode and the anode and the other free edge strip protrudes from the other side. At least one free edge strips has, as a result of a folding and/or a rolling-up process, a thickness that corresponds at least to the thickness of the associated cathode or anode in an adjacent main region.

Abstract: The present disclosure relates to a silicon anode, a method for manufacturing the same, and a battery including the same. Particularly, the silicon anode improves the interfacial contact between the silicon anode and a sulfide-based solid electrolyte layer, and thus the interfacial contact can be maintained uniformly during lithiation even under low pressure, and high delithiation capacity and coulombic efficiency can be realized.
In addition, the battery allows the lithium-alloying metal layer stacked on the anode active material layer to be applied to the silicon anode, and thus the lithium-alloying metal layer stacked on the silicon anode forms alloy with lithium in real time through the conduction of lithium ions from the solid electrolyte during lithiation/delithiation, and the silicon anode becomes soft and adhesive and shows improved interfacial contact between the lithium-alloying metal layer and the solid electrolyte layer, resulting in improvement of the life characteristics and capacity retention of the battery.

Abstract: An alkaline electrochemical cell has a central cathode having a corresponding cathode current collector electrically connected with a positive terminal of the electrochemical cell. The cathode current collector has a tubular shape, such as a cylindrical shape or rectangular shape, extending parallel with the length of the central cathode. The cathode current collector is embedded within the central cathode, such as at a medial point of a radius of the central cathode, thereby minimizing the distance between the cathode current collector and any portion of the central cathode, thereby increasing the mechanical strength of the cathode and facilitating charge transfer to the cathode current collector.
