Abstract

A battery is made by drop on demand printing a first electrode pattern and a second electrode pattern, and applying an electrolyte region over a portion of the first electrode pattern and a portion of the second electrode pattern.

Claims

1. A method of making a battery comprising:

drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium; and

applying an electrolyte region over a portion of the first electrode pattern and a portion of the second electrode pattern.

2. The method of claim 1 wherein drop on demand printing comprises thermally drop on demand printing the first electrode pattern and the second electrode pattern.

3. The method of claim 1 wherein drop on demand printing comprises piezoelectrically drop on demand printing the first electrode pattern and the second electrode pattern.

4. The method of claim 1 wherein drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium comprises drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium having a receiver layer.

5. The method of claim 1 further including heating the first electrode pattern and the second electrode pattern.

6. The method of claim 1 wherein drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium comprises drop on demand printing a first electrode pattern having a first electrode non-linear boundary portion and a second electrode pattern having a second electrode non-linear boundary portion adjacent the first electrode non-linear boundary portion.

7. The method of claim 1 wherein drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium comprises drop on demand printing a first electrode pattern having a first electrode comb-like boundary portion and a second electrode pattern having a second electrode comb-like boundary portion adjacent the first electrode comb-like boundary portion.

8. The method of claim 1 wherein drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium comprises drop on demand printing a first electrode pattern having a first electrode saw-tooth shaped boundary portion and a second electrode pattern having a second electrode saw-tooth shaped boundary portion adjacent the first electrode saw-tooth shaped boundary portion.

9. The method of claim 1 wherein drop on demand printing a first electrode pattern and a second electrode pattern on a carrier medium comprises drop on demand printing a first electrode pattern having a first electrode serpentine shaped boundary portion and a second electrode pattern having a second electrode serpentine shaped boundary portion adjacent the first electrode serpentine shaped boundary portion.

10. The method of claim 1 wherein applying an electrolyte region comprises drop printing the electrolyte region.
