Embodiment Construction

[0031] To illustrate the prior art, the above has figure 1 explained.

[0032] figure 2 , 3 and 4 schematically illustrate three different corrugation structures 18 according to the invention of a battery cell housing 16 which, for example, can be rotationally symmetrical as shown. For better clarity, the folded structure 18 shown in the middle part of the battery cell housing 16 is shown enlarged, wherein the folded structure 18 due to the force F is shown in the upper part of the battery cell housing 16 . The corrugated structure 18 may cover only a portion of the battery cell housing 16 as shown, or cover the entire outer circumference of the battery cell housing 16 . If a force F is now applied to the battery cell housing 16 , the battery cell housing 16 is folded in a predetermined manner due to the fold structure 18 , whereby destruction of the battery cell interior is predictable.

Abstract

A battery cell includes a battery cell housing that is patterned in a form of a folding structure. In another embodiment, a battery cell includes a battery cell housing that is patterned in a form of a sandwich construction which comprises an intermediate layer and two cover layers. In a further embodiment, a battery cell includes a battery cell housing that is patterned in a form of an inversion structure. An exemplary battery includes a plurality of such battery cells, and can be comprised by a motor vehicle.

Description

technical field [0001] The invention relates to a battery cell with a battery cell housing, a battery comprising a plurality of such battery cells, and a motor vehicle comprising the battery. Background technique [0002] Batteries are increasingly used as mobile energy sources for vehicle drives, especially since the development of lithium-ion secondary batteries, which have achieved higher energy levels compared to previous technologies such as lead-acid batteries Density or power density. New battery technologies developed for use in electronic devices such as video cameras or mobile phones place completely different demands on the environmental load than batteries developed for the automotive sector. However, for both fields of application, the same standard is used in one respect. Therefore, the battery must not be subjected to any mechanical damage in the event of an accident, and the housing or, in the case of the vehicle, the chassis must withstand all forces and l...
