The present invention relates to a method for controlling a regeneration procedure of a lithium battery cell () which comprises an anode (), a cathode () and the regeneration electrode (). The method comprises: detecting a current availability of cyclable lithium in the anode (); detecting a current availability of cyclable lithium in the cathode (); passing a first current (I) between the anode () and the regeneration electrode () until the actual availability of cyclable lithium in the anode () corresponds to a targeted availability of cyclable lithium in the anode (); and passing a second current (I) between the cathode () and the regeneration electrode () until the current availability of cyclable lithium in the cathode () corresponds to a targeted availability of cyclable lithium in the cathode ().

Electrode materials and binder materials are used for lithium cells, such as lithium ion cells. To optimize the specific power [W/kg] or power density [W/l] and specific energy [Wh/kg] or energy density [Wh/l], at least one electrically conducting, polymeric binder is used which is selected from the group consisting of polyphenylenes, polypyrroles, polyanilines, polythiophenes and lithium salts thereof. The at least one electrically conducting, polymeric binder is used in a lithium cell.

Detection of corrosion within an at least partially electrically conductive housing of an electric energy storage unit. The electric energy storage unit has a positive terminal and a resistance element between the positive terminal and the housing. State of charge values of the electric energy storage unit for at least one first instant of time and at least one second instant of time are determined. An electrical isolation resistance value between the housing of the electric energy storage unit and at least one reference point for at least one third instant of time may also be determined. A first comparison of a difference of the determined state of charge values with a predefined state of charge difference value for the electric energy storage unit and/or a second comparison of the determined electrical isolation resistance value with a predefined electrical isolation resistance value for the electric energy storage unit are performed.

The invention relates to a receptacle () for at least partially compressively receiving at least one battery cell () for a battery module, wherein the receptacle () has at least two end plates () which can be arranged on two opposing sides of the at least one battery cell (), wherein the end plates () are connected to one another by a plurality of connecting means (), which are fixed to the end plates () and in each case have at least two plug elements (), in such a way that the plug elements () of the connecting means () for fixing the connecting means () to the end plates () engage in bushings () of the end plates () in a plane arranged substantially at right angles to the direction of extension of the connecting means (). In summary, a receptacle () of the type described above allows battery cells () in a particularly simple and cost-effective manner to be fixed in a battery module and allows the performance of a battery module to be maintained, irrespective of the temperature, by at least temporary bracing.

The invention relates to a frame device () for accommodating storage cells () of an energy storage module (), in particular a battery module, comprising&#x2014;two plate-like closure elements () which form two ends () of the frame device () that are opposite one another along an axis (), &#x2014;connection elements () which are arranged on mutually opposite sides () of the frame device () and which extend from one end () to the other end () of the frame device () and mechanically connect the two closure elements () over a distance. For connection to the two closure elements (), provision is made for each of the connection elements () to be provided at each of the ends thereof with a pin () which is oriented transversely to the axis () and which respectively engages in a cutout () in one of the closure elements () and is releasably fixed there by means of a respective latch-type securing element (). The invention further relates to a corresponding energy storage module ().
