A battery cell comprises at least one galvanic cell, a first cell housing element, and a second cell housing element. The two cell housing elements jointly substantially completely enclose the galvanic cell. The first cell housing element has inner recesses on the inner surface thereof, which inner recesses are, on an outer surface of the first cell housing element lying immediately opposite the inner surface, outer protrusions for electrically contacting a first further battery cell. First compensation elements are complementary to the inner recesses in such away and are arranged in the inner recesses in such a way that the first compensation elements, together with the inner recesses, form a substantially flat inner surface of the first cell housing element.

Battery cell comprising at least one galvanic cell, battery, and method for producing a battery cell

The invention relates to a battery module having a plurality of battery cells, in particular lithium-ion battery cells, having a plurality of partitions (), wherein a battery cell () is arranged between two partitions (), and a spring element () is furthermore arranged between two partitions () adjacent to a battery cell (), in particular a tension and/or compression spring element, which is arranged in a manner contacting and/or connected to the two partitions () such that a value of a deformation constant () of the spring element () determines a force transmitted by the two partitions () to the battery cell ().

Battery module having a plurality of battery cells, method for the production thereof, and battery

The invention relates to a battery module having a plurality of battery cells, in particular lithium ion battery cells, comprising a plurality of separating walls (), wherein a battery cell () is arranged between two separating walls () and a first compensating element () is arranged between a first battery cell () and a separating wall () adjacent to the first battery cell () and a second compensating element () is arranged between a second battery cell () and a separating wall () adjacent to the second battery cell (), characterized in that the first compensating element () and the second compensating element () have a different value () of a deformation constant.

The invention relates to a battery cell () comprising a first terminal (), which is electrically conductively connected to a first electrode, and a second terminal (), which is electrically conductively connected to a second electrode, the first terminal () being arranged inside the second terminal (). The invention further relates to a battery module () comprising corresponding battery cells (), to a battery, to a method for producing the battery module (), and to a use for the battery.
