Embodiment Construction

[0038] exist figure 1 A schematic diagram of an accumulator 10 according to the invention is shown in . Such an energy store 10 can in principle be any type of energy store, in particular a battery such as, for example, a rechargeable accumulator. The energy store 10 is, for example, a lithium-ion battery. Possible areas of application include electrically powered vehicles, such as computers such as notebooks, mobile phones, smartphones, power tools and other applications.

[0039] Such an energy store 10 contains a battery chamber in which an anode, a cathode and an electrolyte arranged between the anode and the cathode are arranged. Furthermore, a separator is arranged in a known manner between the anode and the cathode.

[0040] The anode and the cathode can in principle be designed in a manner known for energy accumulators. In the purely exemplary case of a lithium-ion battery, the anode can be an electrode that contains metallic lithium or intercalates lithium. The c...

Abstract

The invention relates to an energy store (10), in particular a lithium-ion battery. In order to provide a particularly reliable operation of the energy store (10), or to be able to quickly and reliably detect damage to the energy store (10) and thereby reduce or avoid actuating other components or the energy store (10) The accumulator (10) contains a battery chamber in which an anode, a cathode and an electrolyte arranged between the anode and the cathode are arranged, the battery chamber passing at least partially through the casing (12) separated from the external environment, and wherein the housing (12) has a detection medium (18) for detecting at least one component and The reaction product of this component. The invention also relates to a method for producing an energy store (10) and the use of a test medium (18) for producing an energy store (10).

Description

technical field [0001] The invention relates to an energy accumulator. In particular, the invention relates to a lithium ion battery. Background technique [0002] Lithium-ion batteries are widely promoted as energy accumulators in many everyday applications. They are used, for example, in computers such as notebooks, mobile phones, smartphones and other fields of application. Such batteries are also advantageous in the electrification of vehicles, such as motor vehicles, which are currently being strongly advanced. [0003] Various technical solutions are known for avoiding damage caused by energy stores such as lithium-ion batteries, for example. They are intended, for example, to reduce the risk of the accumulator overheating, burning or emitting harmful gases or dusts in the event of vehicle damage. Overall, energy stores, such as lithium-ion accumulators, for example, can be used without significant damage due to appropriate safety measures. [0004] A battery pack...
