Deferred assembly construction of electrochemical cells
First Claim
1. A method of constructing a succession of electrochemical cells arranged for deferred assembly along an in-line press comprising the steps of:
- advancing first and second electrode layers along the press with at least one of said first and second electrode layers being printed in a repeating pattern;
applying an electrolyte layer out of contact with at least said first electrode layer for interrupting an ionically conductive pathway between said first and second electrode layers; and
finishing said first and second electrode layers and said electrolyte layer into one or more formats with the electrolyte layer being maintained out of contact with at least said first electrode layer.

Abstract
Printed electrochemical cells including both power cells and display cells are arranged in a partially assembled condition to extend shelf life of the cells. The partially assembled condition is also used as a switching mechanism for controlling activation of some of the cells. The active components of the cells include two electrodes and an electrolyte layer that is maintained out of contact with at least one of the electrodes for interrupting an ionically conductive pathway between the electrodes. The electrolyte is preferably an electrolytic adhesive that is protected by a release layer until the cells are needed for service.

at least one of the first and second electrode layers being printed in a repeating pattern along one or more webs;
the electrolyte layer being printed along the one or more webs out of contact with at least one of the first and second electrode layers for interrupting a succession of ionically conductive pathways between the first and second electrode layers;
pairs of electrical contacts being laid out in electrical communication with the first and second electrode layers for connecting the succession of electrochemical cells to external load circuits; and
portions of the electrolyte layer being movable into contact with portions of the at least one electrode layer for completing the ionically conductive pathways between said first and second electrode layers and making electrical power from the electrochemical cells available to the external load circuits.
