METHOD FOR ASSEMBLY OF ELECTROCHEMICAL ELEMENTS UNIT OF THERMAL CHEMICAL CURRENT SOURCE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC H01M6/36 

FIELD: electrical industry.

SUBSTANCE: invention can be used in the production of thermal chemical current sources. A block of electrochemical cells, consisting of sequentially stacked tablets of the cathode, electrolyte, anode and pyrotechnic elements, is assembled in a channel formed by four guides in the form of plates arranged in pairs diametrically on a cylindrical base with a central hole for placing a cover with pressure seals and a threaded pin equipped with a protective silicone tube, configured for horizontal movement by adjusting screws, two diametrically located guides are equipped with fixing nuts, with which the punch in the form of a die is fixed during crimping, the block of electrochemical elements is fixed after fixing with ties made in the form of metal strips welded one end to the cover, and the other end to the pressure plate located in the upper end of the block of electrochemical elements.

EFFECT: reliable fixation of the tablets of the block of electrochemical elements and, as a result, a decrease in the number of defective products due to the elimination of damage to the tablets, pressure leads and the threaded pin of the cover during assembly.
