Abstract: A cell module for lithium-ion batteries includes at least two lithium-ion cells, in particular lithium-ion battery cells, a cell module housing that has at least one lateral wall, and at least one electrical insulation between the cells. The electrical insulation is configured in one piece with the cell module housing.

Abstract: The invention relates to a holding-down means (100) for fixing battery cells (2) in a battery submodule (70), comprising positioning elements for positioning the holding-down means (100) relative to the battery cells (2), and comprising guide elements for guiding cell connectors (80) which connect the battery cells (2), wherein gas-venting openings which pass through from a top side to a bottom side are provided in a central region of the holding-down means (100), and wherein the sealing elements which surround the gas-venting openings are provided on the bottom side of the holding-down means (100). The invention also relates to a battery submodule (70) which comprises a plurality of battery cells (2) and cell connectors (80) which connect the battery cells (2), and also at least one holding-down means (100) for fixing the battery cells (2).

Abstract: A method for producing a battery cell (8) wherein, after the metallic bottom part (16) has been joined materially to the metallic wall part (14) and the second electrode side (28) has been joined materially to the feedthrough bushing (32), a metallic cover part (12) is joined materially to the metallic wall part (14), and wherein the material joining of the metallic bottom part (16) to the metallic wall part takes place only after the material joining of the first electrode side (26) of the battery roll (24) to the metallic bottom part (16).

Abstract: A battery system (BS), containing at least one battery device (BV) and at least one operating device (BTV) for operation of the battery system (BS) and/or of the at least one battery device (BV), and at least one further device (V), wherein the at least one further device (V) is intended to create a physical distance between two component parts of the battery system (BS) and in particular between the at least one battery device (BV) and a further component (K) of the battery system (BS), or between at least two component parts of the at least one battery device (BV), wherein the at least one operating device (BTV) is arranged at least partially within the at least one further device (V).

Abstract: In a switch including a switch frog (1) with a movable frog point (2) and wing rails (5, 6), wherein the wing rails (5, 6) in the region of the frog point (2) each have a rail profile which is lower than that of a standard rail, the wing rails (5, 6) are designed as Vignol rails whose region configured with a lower rail profile is produced by metal-forming departing from the Vignol rail profile.

Abstract: A device and method provide for measuring the position of the edge of a material web by illuminating an area of the edge area and detecting shadows cast by the material web. Two or more transmitters arranged in a line transverse to the edge of the material web are used for illumination. A linear sensor also arranged transverse to the edge of the material web is used to sense the locations of the shadows. The position of the edge of the material web is detected from the sensed shadow and the locations of the transmitters and sensors.
