Elektrochemischer Anzeige- und Zeitmeßmechanismus mit wanderndem Elektrolyt

Electrochemical display and timing mechanism with migrating electrolyte

Electrochemical display cell 10 has a layered construction including two electrode layers 26, 28 and an electrolyte layer 30 occupying distinct areas of a substrate. Electrolyte layer 30 overlaps most of one electrode layer 28 and contacts a smaller portion of the other electrode layer 26 which is made of a thin film. The cell is activated by electrically connecting the electrodes 26 and 28 by way of conductive portion 32 thereby supporting an electrochemical reaction in the electrolyte layer 30 that progressively erodes the electrode 26 at the boundary 38 so as to reduce the area covered by the electrode 26 and increase that covered by the electrolyte 30. The thin-film electrode layer 26 recedes at the electrode/electrolyte boundary 38 at a rate governed by the rate of the electrochemical reaction. This provides an irreversible visual indication of the passage of time.

Method and apparatus for printing lithium patterns on a press

A printing station conveys a supply of molten lithium from a heated tank to a nozzle within a protective shroud. A web traverses a chiller also within the shroud. The nozzle dispenses discrete amounts of the molten lithium onto successive portions of the web in contact with the chiller. The chilled lithium solidifies into solid lithium patterns. A sealer also within the shroud prevents exposure of the solid lithium patterns to ambient air. The station can be incorporated into an in-line press for forming a succession of electrochemical cells.

MASK-LESS FABRICATION OF THIN FILM BATTERIES

Thin film batteries (TFB) are fabricated by a process which eliminates and/or minimizes the use of shadow masks. A selective laser ablation process, where the laser patterning process removes a layer or stack of layers while leaving layer(s) below intact, is used to meet certain or all of the patterning requirements. For die patterning from the substrate side, where the laser beam passes through the substrate before reaching the deposited layers, a die patterning assistance layer, such as an amorphous silicon layer or a microcrystalline silicon layer, may be used to achieve thermal stress mismatch induced laser ablation, which greatly reduces the laser energy required to remove material.
