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.
