Abstract
A method and an apparatus are disclosed for the production of electrical energy storage devices, in which two separators are fed alongside one another, two anode feeders arrange in an alternating manner a succession of anodes one after the other between the two separators, two cathode feeders arrange a succession of cathodes one after the other on the outer sides of the two separators in an alternating manner so that only one cathode is superimposed on each anode, after which a cutting device separates various discrete elements, each consisting of only one anode and only one cathode with the interposition of portions of the two separators.
Claims19
A method for the production of electrical energy storage devices, said method comprising the steps of:
- feeding a first separator and a second separator;
- arranging a sequence of first electrodes one after the other between said first and second separator;
- arranging a sequence of second electrodes one after the other on a side of the first separator opposite to the second separator, the second electrodes being superimposed over respective first electrodes with the interposition of the first separator, second electrodes not being arranged on some portions of the first separator overlapped to one or more first electrodes;
- arranging a sequence of third electrodes one after the other on a side of the second separator opposite to the first separator, the third electrodes being superimposed over respective first electrodes with the interposition of the second separator, third electrodes not being arranged on some portions of the second separator superimposed to one or more first electrodes;
- the second electrodes being superimposed over first electrodes which in turn are superimposed over portions of the second separator on which third electrodes are not arranged, the third electrodes being superimposed over first electrodes which in turn are superimposed over portions of the first separator on which second electrodes are not arranged;
- said first and second separators comprising two continuous elements, said method comprising the step of separating discrete elements from a product comprising said first, second and third electrodes and said first and second separators, each discrete element comprising only one first electrode between the separators and only one other electrode that consists of a second electrode or a third electrode.
