Abstract

A method for manufacturing lithium-ion battery modules, including the following: positioning an elastic plastic device between at least two cells of a battery module; path-controlled compression of the at least two cells of the battery module and of the elastic plastic device situated between the at least two cells. Also described is a corresponding lithium-ion battery module.

Description

technical field [0001] The invention relates to a method for producing a lithium-ion battery module and a corresponding lithium-ion battery module. Background technique [0002] image 3 A schematic diagram of an exemplary arrangement for constructing a mechanically pressed battery is shown. [0003] exist image 3 Among them, reference numeral 10 denotes the cover plate of the electronic device, 20 denotes the control electronics, 30 denotes the laser-welded connection rail, 40 denotes the connection cover, 50 denotes the pressure strap, 60 denotes the pressure plate, 70 denotes the prismatic lithium-ion battery And reference numeral 80 designates a cooling body. [0004] It is known that the mechanical stresses acting on lithium-ion batteries have a positive influence on their service life under certain circumstances. [0005] In addition, mechanical compression is often used for mechanical fixation. Batteries are also often pressed for thermal contact to cool the batte...
