METHOD FOR ASSEMBLING LITHIUM MANGANESE DIOXIDE ELEMENT AND AUTOMATIC WINDING DEVICE FOR METHOD Russian patent published in 2024 - IPC H01M6/10 

FIELD: electrical engineering.

SUBSTANCE: invention relates in particular to the equipment and technology for the production of chemical current sources (CCS), and can be used in the production of rolled lithium CCS. The technical result is ensured by assembling the lithium-manganese dioxide element, which includes applying the cathode mass to an aluminium mesh, cutting out cathode blanks from it, welding cathode current leads to the cathode blanks, fixing the insulation on the cathode current lead and the end of the cathode, welding the current leads to the lithium foil strip and fixing insulation on them to obtain an anode tape. A cathode, a strip of separation material and an anode tape are rolled up on a winding device into a roll, and the welding of the current leads to the anode tape and the insulation is secured to them when it is fed to the winding. The roll is rolled up in the process of continuous simultaneous feeding of the cathode, the anode tape and the strip of separation material to the receiver of the winding device, made automatic. When the roll reaches the required and sufficient dimensions, the anode tape and the strip of separation material are cut off, and the element is assembled, including welding the anode current conductor to the bottom of the element body, laying a dielectric gasket on the bottom of the element body, laying a dielectric gasket on the end of the roll, welding the cathode current lead to the mounting cover of the element body, pouring electrolyte into the element body from an automatic dispenser, inserting an o-ring, membrane, gasket and fuse into the element body, rolling the element, installing heat-shrinkable film, preparing the element for storage by discharge for 3-5 minutes with 0.1C current. The element assembly operations are carried out in a box with flowing dried air.

EFFECT: automation of the assembly process, which makes it possible to reduce the duration of auxiliary operations and reduce the percentage of defects due to wear of cutting knives and lithium passivation.
