An electrochemical energy storage device (1) comprising a casing (2), in which a plurality of flat galvanic cells (3) are arranged. Between two adjacent flat galvanic cells is in each case, a flat heat conducting body (4) and/or a flat elastic body (5) arranged. Preferably, the flat galvanic cells, the flat heat conducting bodies and/or the flat elastic bodies exert upon each other at the contact surface areas, a force (11) corresponding to a surface pressing, and the casing has a wall with a structure or with structures (8, 9), in which a heat conducting body (4) engages such, that said heat conducting body may not be shiftable in the direction of the force (11), acting on the contact surface areas.
摘要:
A profile strip to border an electrochemical energy storage device having at least one, essentially, longitudinally extending first recess, which is bordered by a first arm and a second arm. The first and the second arm are made such that they are attachable to opposite sides of an boundary area of the electrochemical energy storage device, and at least partially connected to each other with a backside part. In a method of producing such a profile strip for an electrochemical energy storage device, at least one first recess is inserted into the profile strip by a suitable method, and the profile strip is converted in said first recess from a first, stretched, state into a second, angled, state. The corner resulting from bending may have a connection by force-fit or by material engagement.

摘要:
The invention relates to a method for the production of epichlorohydrin, wherein a chloropropane-containing ally chloride in excess is reacted in a first reaction stage with hydrogen peroxide. The non-reacted ally chloride is separated and returned to the reaction, wherein part of the separated ally chloride is added to a second reaction stage and reacted with hydrogen peroxide, wherein the hydrogen peroxide quantity is selected in the second reaction stage such that the ally chloride is largely reacted. The chloropropanes are separated from the reaction mixture of the second reaction stage by means of distillation and removed from the process.
摘要:
A battery includes a stack of bipolar individual battery cells, each of which includes an electrode stack and two sheet metal covers bounding the individual battery cell at least in the stacking direction. The electrode stack is connected to at least one of the sheet metal covers by at least one weld. In the region of the at least one weld, the sheet metal cover welded to the electrode stack and/or the sheet metal cover of the adjacent individual battery cell in contact with the sheet metal cover is/are of a set-back design. As a result, the sheet metal covers of adjacent individual battery cells do not have any contact in the region of the at least one weld.
