ELECTRODE UNIT, LAYERED STORAGE BATTERY AND METHOD OF PRODUCING SUCH BATTERY Russian patent published in 2017 - IPC H01M10/04 H01M2/02 H01M2/18 

FIELD: electricity.

SUBSTANCE: invention relates to an electrode unit of secondary current sources with a layered arrangement of electrodes structure. Electrode unit comprises: an electrode group having a layered structure with a positive electrode, a negative electrode and a separator located between them having the shape of a slipcover. Unit is equipped with covers arranged at two ends of the electrode group in the direction of a set of layers and the first holder attached to the outer surfaces of the electrode group and the covers, herewith the first holder is electrically connected to the first electrode, which is one of the positive and the negative electrodes, and is not connected electrically to the second electrode, which is the other electrode of the positive and the negative electrodes, herewith between the electrode groups there is a central through hole located in the center, wherein the second holder is located on the side of the through hole and is isolated from the first holder by the cover. Multiple formed thus electrode units can be arranged in series one after another and placed in an outer shell, after which in the through hole a current collector is inserted.

EFFECT: higher reliability due to elimination of electrodes displacement, easier assembling of a storage battery, as well as higher efficiency of cooling the layered storage battery unit are the technical result of the invention.
