A method for producing an injector which is designed in particular to inject fuel into an induction pipe or directly into a combustion chamber of an internal combustion engine. The method includes providing an injector base element, providing a rod that is insertible into a through hole of the injector base element, producing a negative matrix of a spray orifice element on an axial end of the rod, inserting the rod into the through hole of the injector base element, positioning the negative matrix situated on the rod relative to the injector base element, producing the spray orifice element having at least one spray orifice by applying a galvanization layer on a downstream end, in the injection direction, of the injector base element and on the negative matrix, and removing the rod and the negative matrix.

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.

Insulating of adjacent lithium-ion batteries by complete overmoulding/pouring of containers in a device

The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein a cover plate () forming a part of a battery cell housing, which is designed as a plane sheet in a conventional manner, is modified to avoid short circuits between the poles of the battery cell due to moisture, for example. To this end, the cover plate () is provided with a central area () and an edge area () surrounding said central area (). The central area () is located above an opening () to be closed off by the cover plate () of a container () forming a part of the battery cell housing, whereas the edge area () extends inside said opening (). Thus, occurring moisture can drain off the platform-like raised central area () sideways toward a channel () in the edge area (), and evaporate from there.

The invention relates to a battery cell (), in particular a lithium ion battery cell, in which a wrapping element, two current collectors and an electrolyte are accommodated in a housing (). The prismatically formed housing () comprises a container that is open towards the upper side and a cover arrangement having a cover plate () closing the opening () of said container. The cover plate () and a wall of the container () are designed in the region of the opening () in such a manner that the wall prevents a movement of the cover plate () from the opening by means of a positive connection. An elastically compressible sealing element () is provided between the wall and a wall surface of an outer edge () of the cover plate directed towards said wall, in order to seal the cover plate () hermetically against the container (). On the basis of the positive connection between the cover plate () and the edge of the container () a sealing effect can hereby likewise increase while the inner pressure in the housing () increases. The invention relates to a battery cell (), in which it can be prevented that the cover plate () must be welded to the container ().

A fuel distributor, which is used, in particular, for fuel injection systems of mixture-compressing, internal combustion engines having externally supplied ignition, includes a distributor pipe, a first holder and at least one second holder. The distributor pipe has a longitudinal axis. In this connection, the first holder and the second holder are situated at the distributor pipe so as to be axially set apart from one another with respect to the longitudinal axis. The distributor pipe is designed to allow axial length compensation. It is also possible for at least one holder to be designed to allow axial length compensation.

The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein compared to conventional battery cells, a number of components can be reduced. The battery cell has at least one winding element, two current collectors each electrically connected to one of the electrodes of the winding element, and a metal housing. In order to be able to establish an electrical contact between one of the electrodes of the winding element and the housing, one of the current collectors is specifically configured and arranged such that said current collector is in direct mechanical and electrically conductive contact with the housing. To this end, said housing contact current collector () can be provided with a suitably wide plate-shaped area (), which in edge regions () that are bent away at a right angle can rest against an interior wall of the housing of the battery cell in a planar manner, and can establish an electrical contact therewith.

The invention relates to a battery cell () for pre-stressed battery modules (). The invention further relates to corresponding pre-stressed battery modules () and corresponding production methods. The battery cell () has a cell housing () and a chemicals carrier (). The chemicals carrier () is arranged in the cell housing (). The cell housing () has a bulging design.

Restraining of battery cells by way of a cambered design of the battery housing

The invention relates to a battery cell () having a cell housing () which comprises a housing container () and a housing cover (), two electrodes that are arranged in an inner region of the housing container (), an electrolyte material that is arranged in the inner region of the housing container () and that surrounds the electrodes, and two electrical contacts which in each case are electrically coupled to one of the electrodes and which extend from the inner region of the housing container () through the housing cover () into a region outside of the cell housing (), wherein the housing cover () has an overlap area () at an outer edge, in which overlap area the housing cover () and an edge region of the housing container () are arranged parallel to each other, wherein in the overlap area () a flanged seam () is formed, in order to close the cell housing ().
