Application: Feedthrough system, method for producing a feedthrough system, electrochemical cell, and electrochemical system (Patent ID: US20230216162A1)

The patent filed by ElringKlinger AG describes a feedthrough system for an electrochemical system. The system includes a wall component with one or more feedthrough openings, one or more lines that pass through these openings, and a fastening device that connects the lines to the wall component in one or more connection regions. The fastening device may include sealing elements that surround the lines in the connection regions, which can be formed by pouring a potting material or injecting an injection molding material into the region. The wall component may have receiving recesses to hold the potting material or injection molding material, and the fastening device may have annular frame elements that are filled with the potting material or surround the connection region. The potting material can be made of glass or polymer material, and may include fillers such as silicon oxide or metal nitride. The sealing elements are made of a material that repels water, with a contact angle greater than 90°. The lines may have adhesion promoter structures, such as sheathing or coating, that are chemically and physically compatible with the fastening device. The feedthrough system may also include stabilizing elements with raised parts and support elements for the lines. The fastening device may have relief elements to fix the lines to the outer side of the wall component. The patent also describes a method for producing the feedthrough system and an electrochemical cell that incorporates the feedthrough system. The cell may have a burst element or a fuse, and the feedthrough system may include an electrolyte filling opening. The patent also covers an electrochemical system comprising multiple electrochemical cells.
