Embodiment Construction

[0025] figure 1 A schematic side view of a preferred embodiment of the battery cell 1 according to the invention is shown. The battery cell 1 has a housing 2 in the form of a cuboid open on one side with a cavity 21 , a housing cover 3 and an electrode assembly 4 arranged in the housing 2 . The connection terminals 31, 32 of the electrode are generally composed of at least one first electrode, a second electrode and a separator arranged between them, wherein each electrode has at least one current collector 51, 52, which is directed towards the shell The body cover 3 protrudes. In this case, in the assembled state of the battery cell 1 , the electrode assembly 4 is arranged in the cavity 21 of the housing 2 and the housing cover 3 is welded to the upper edge of the housing 2 . Furthermore, the battery cell 1 has a plastic component 6 which surrounds the current collector / current collectors 51 of the first electrode and the current collector / multiple current collectors 52 of...

Abstract

According to the invention, a battery cell (1) is provided, comprising a housing (2), a housing lid (3) with connections (31, 32) provided therein, an electrode assembly (4) arranged in the housing (2) and consisting of at least one first electrode, a second electrode and a separator provided between said electrodes, wherein with each electrode has at least one current collector (51, 52) protruding in relation to the housing lid (3), and a plastic component (6) which encloses, separated from one another, the current collector (51, 52) of the first electrode and of the second electrode, and enables a current feed-through from the electrodes to the connections (31, 32). In addition, a battery is provided comprising at least two battery cells (1) of this type, wherein the battery cells (1) are connected together in series or in parallel.

Description

Background technique [0001] The invention relates to a battery cell, preferably a lithium-ion battery cell, which has a plastic component for surrounding electrodes. Furthermore, the invention relates to a battery, preferably a rechargeable lithium-ion battery, which has at least two of the battery cells according to the invention. Here, the term "battery" means that at least two battery cells are connected to each other in series or in parallel. The terms "battery cell" and "cell" are used synonymously herein. [0002] Recently, highly developed rechargeable batteries, also known as secondary batteries or accumulators, that is to say a plurality of individually, electrically connected Rechargeable battery cells are connected in parallel or in series to form battery packs or so-called battery modules. In the future, application possibilities for such batteries will be realized not only in stationary applications (for example in wind power plants) but also in the automotive ...
