Abstract

A method of forming a battery includes: a) providing a cathode base which comprises: a first nonconductive surface; a first conductive layer superjacent the first nonconductive surface; the first conductive layer comprising a first area; and a cathode layer superjacent the first conductive layer leaving at least a portion of the first area exposed; b) providing an anode base which comprises: a second nonconductive surface; a second conductive layer superjacent the first nonconductive surface, the second conductive layer comprising a second area; and an anode layer superjacent the second conducive layer leaving at least a portion of the second area exposed, the anode layer comprising an alkali metal; and c) aligning and coupling the anode layer of the anode base with the cathode layer of the cathode base, wherein the aligning and coupling leaves at least a portion of the first area and at least a portion of the second area exposed for electrical connection. The invention also encompasses batteries formed by such methods.

Claims

1. A battery comprising:

a first nonconductive sheet having a first orifice therethrough;

a second nonconductive sheet having a second orifice therethrough;

a cathode and an anode sandwiched between the first and second nonconductive sheets; and

a cathode terminal in electrical contact with the cathode and an anode terminal in electrical contact with the anode, the cathode and anode terminals being between the first and second nonconductive sheets and being exposed for electrical contact through the first and second orifices, respectively.

2. The battery of claim 1 wherein the first and second nonconductive sheets are rectangular in shape.

3. The battery of claim 1 further comprising an electrolyte film between the anode and cathode.

4. The battery of claim 1 wherein the orifices are rectangular in shape.

5. The battery of claim 1 wherein the cathode is adjacent the first nonconductive sheet and the anode is adjacent the second nonconductive sheet, the battery further comprising a first conductive layer between the cathode and the first nonconductive sheet, and a second conductive layer between the anode and the second nonconductive sheet.

6. The battery of claim 5 wherein one or the other of the first and second conductive layers comprises a cured conductive ink.

7. The battery of claim 5 wherein both the first conductive layer and the second conductive layer comprise a cured conductive ink.
