Problems solved by technology

Here, the ratio of length to radius can only be adjusted to a limited extent
The large number of smaller round cells requires a large number of peripheral devices for fastening, electrical connection, cooling, etc., so that the limited available installation space can only be used unfavorably
The small number of larger circular cells has the disadvantage that uniform cooling of the larger circular cells is problematic

Abstract

A battery cell 100 in the form of a round cell, having: at least one electrode element 10 having an inner side I and an outer side A and at least one temperature control element 20, wherein the innerside of the at least one electrode element 10 is spaced apart, at least in sections, from the outer side A of the at least one electrode element 10 by means of the temperature control element 20.

Description

technical field [0001] The invention relates to a battery cell in the form of a round cell (Rundzelle) according to the preamble of the independent device claim and a method for producing a round cell according to the independent method claim A method of forming a battery cell. Background technique [0002] The goal pursued in battery pack development is to design the battery pack and the individual battery cells as large as possible and to design the enclosure as small as possible so that all mechanical Load condition. In order to achieve maximum power density and energy density, the structural components must be designed in a space-saving and as far as possible without redundancy. At the same time, in addition to the installation space for the battery cells, sufficient installation space must be maintained within the housing for electrical wiring and control devices. The battery cells must in turn have the best possible thermal contact with the cooling device. Likewise...
