Powerstream ( http://www.powerstream.com/thin-primary-lithium.htm http://www.powerstream.com/thin-primary-lithium.htm ) makes a number of paper-thin primary and rechargable cells. I haven't personally worked with them, but the specs look incredible.

- maggit 14y agoThat's amazingly thin! However, it is still thicker than a regular business card [1], and it is probably unrealistic to make the card exactly the same thickness as the thickest part on it :( [1]: Assuming 350g/m^2 paper (http://en.wikipedia.org/wiki/Business_card http://en.wikipedia.org/wiki/Business_card) with a thickness just shy of 0.45mm (http://www.answerbag.com/q_view/2457344 http://www.answerbag.com/q_view/2457344)
- thaumaturgy 14y agoFWIW I use plastic business cards which are quite a bit thicker, and pretty effective. With 3D printers being what they are now, you might even be able to print your own business cards around one of these thin batteries.
