Abstract

The invention is directed to batteries having a nonconductive layer next to a conductive layer wherein the conductive layer comprises a cured conductive ink. The anode is against the conductive ink layer.

Claims

1. A battery comprising:

a first nonconductive layer;

a first conductive layer against the first nonconductive layer;

a cathode against the first conductive layer;

a second nonconductive layer;

a second conductive layer against the second nonconductive layer, the second conductive layer comprising a cured conductive ink; and

an alkali metal attached to the second conductive layer.

2. The battery of claim 1 wherein the alkali metal is lithium.

3. The battery of claim 1 wherein the first conductive layer comprises a cured conductive ink.

4. The battery of claim 1 wherein the first nonconductive layer comprises an anode access slot to provide electrical access to the alkali metal.

5. The battery of claim 1 wherein the second nonconductive layer comprises a cathode access slot to provide electrical access to the cathode.

6. The battery of claim 1 wherein the first nonconductive layer comprises an anode access slot to provide electrical access to the alkali metal, wherein the second nonconductive layer comprises a cathode access slot to provide electrical access to the cathode, and further comprising:

an anode contact adjacent the second nonconductive layer; and

a cathode contact adjacent the first nonconductive layer.

7. The battery of claim 6 wherein the anode contact comprises a cured conductive ink, and wherein the cathode contact comprises a cured conductive ink.

8. The battery of claim 6 wherein the anode contact comprises a cured conductive ink and a tip comprising a cured carbon based polymer thick film ink, and wherein the cathode contact comprises a cured conductive ink and a tip comprising a cured carbon based polymer thick film ink.

9. A battery comprising:

a nonconductive layer;

a conductive layer against the nonconductive layer, the conductive layer comprising a cured conductive ink; and

an alkali metal fused to the conductive layer.

10. The battery of claim 9 wherein the alkali metal is lithium.

11. The battery of claim 9 wherein the conductive layer further comprises a metal layer plated to the cured conductive ink.

12. The battery of claim 9 wherein the conductive layer further comprises a metal layer plated to the cured conductive ink and wherein the alkali metal is fused to the metal layer.
