Abstract

A battery cell in the form of a round cell, having: at least one electrode element having an inner side and an outer side and at least one temperature control element, wherein the inner side of the at least one electrode element is spaced apart, at least in sections, from the outer side of the at least one electrode element by means of the temperature control element.

Claims (31)

1. A battery cell in the form of a round cell, having:

at least one electrode element having an inner side and an outer side and at least one temperature control element,

wherein the inner side of the at least one electrode element is spaced apart, at least in sections, from the outer side of the at least one electrode element by means of the temperature control element,

wherein a plurality of electrode elements are provided to form a plug-in system, and wherein a plurality of tubular or cylindrical packing material filling bodies are provided, so that a scalable number of electrode elements can be arranged on an outer side of a corresponding packing material filling body in order to provide an adaptable plug-in system, and in order to enable variable adaptation of the range and the power of the battery cell, and

wherein the inner side of the at least one electrode element is spaced from the outer side of a corresponding packing material filling body, at least in sections, by means of the at least one temperature control element.

2. The battery cell according to claim 1 , wherein

the at least one electrode element includes at least two electrode elements, and/or

the at least one temperature control element is situated between the inner side of a first electrode element and the outer side of a second electrode element.

3. The battery cell according to claim 1 , wherein

only one electrode element is provided, which is wound to form a winding, and/or

the at least one temperature control element is wrapped between the inner side of the electrode element and the outer side of the same electrode element.

4. The battery cell according to claim 1 , wherein

the at least one electrode element has a strip-shaped design, and/or

the at least one temperature control element has a strip-shaped design.

5. The battery cell according to claim 1 , wherein the at least one temperature control element is designed in the form of a cooling element and/or a cooling conduit through which a cooling medium flows.

6. The battery cell according to claim 1 , wherein

a housing for the battery cell is provided, and/or

the outer side of the at least one electrode element is spaced apart, at least in sections, from the housing by means of the at least one temperature control element.

7. The battery cell according to claim 2 , wherein the at least two electrode elements have a cylinder shell-shaped design and/or are situatable coaxially with respect to one another, and/or the at least two electrode elements have different diameters.

8. The battery cell according to one claim 1 , wherein the at least one temperature control element includes at least two temperature control elements.

9. The battery cell according to claim 8 , wherein

the at least two temperature control elements have a cylinder shell-shaped design and/or are situatable coaxially with respect to one another, and/or

the at least two temperature control elements have different diameters.

10. The battery cell according to claim 1 , wherein the at least one packing material filling body includes at least two packing material filling bodies having different diameters, on which a scalable number of the at least two electrode elements may be situated.

11. A method for manufacturing the battery cell in the form of a round cell according to claim 1 , comprising:

positioning the at least one temperature control element on at least one electrode element of the battery cell in such a way that the inner side of the at least one electrode element is spaced apart, at least in sections, from the outer side of the at least one electrode element by means of the temperature control element.

12. The method according to claim 11 , further comprising:

plugging together at least two electrode elements, so that the at least one temperature control element is situated between the inner side of a first electrode element and the outer side of a second electrode element.

13. The method according to claim 11 , further comprising:

winding only one electrode element, so that the at least one temperature control element is wrapped between the inner side of the electrode element and the outer side of the same electrode element.

14. The method according to claim 11 , further comprising: providing at least two packing materials having different diameters, and/or inserting at least one of the two packing materials instead of a cylindrical electrode core and/or instead of at least one of the at least two electrode elements.
