The Great Big Guide to Paper Circuits
Powering Your Project
Paper circuit projects can be easily powered with a 3V coin cell battery. We recommend a 20mm or 12mm diameter battery for small projects such as greeting cards.
Most common coin cell batteries look like the ones above - the top and sides of the battery are positive and a textured bottom is negative. This can prove tricky for attaching to our traces, so we'll go over a few techniques to try.
You can also find some good examples of battery use and power in this tutorial:

Create Your Own Battery Holder
Making a battery holder with the materials you have on hand is quick and easy! Here are a few different methods for crafting your own battery holder.
Copper Tape Holder:
Paper and Copper Tape Holder:
Chibitronics has a tutorial on using copper tape and a piece of paper to make a battery pouch.

Battery Holder Modules
Battery holder modules can be soldered onto copper tape or glued with conductive glue or paint. Always remember to remove the battery from the holder before soldering.
You can also purchase batteries with solder tabs - these can then be soldered, glued with conductive glue, or sometimes even pressed in place with clear tape to attach to a circuit. When shopping for a tabbed battery, try to find one with insulation around the sides to avoid accidental shorts.
