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 cathode is against the conductive ink layer.

Claims

1. A battery comprising:

a nonconductive layer;

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

a cathode against the conductive layer.

2. The battery of claim 1 wherein the cathode comprises a cured conductive paste.

3. The battery of claim 1 further comprising:

an anode proximate the cathode;

an anode terminal in electrical contact with the anode;

an electrolyte film between the anode and the cathode; and

wherein the nonconductive layer is a nonconductive sheet having an orifice therethrough, the anode terminal being exposed for electrical contact through the orifice.
