A simple battery can be made by pushing a screw (best if it is zinc-coated/galvanised) and a piece of copper into a lemon and connecting these two electrodes using wires to the device you want to power. This cell can produce enough power to run an LCD clock/watch.
You can get copper flashing from a hardware store and cut out a strip of it, or you can use a bunch of copper wire (the more surface area exposed to the liquid, the more electrical current is produced). Or, as before, you can get pre-cut strips from our catalog. The aluminum-copper-coke battery will produce about three quarters of a volt.
Your battery can generate electricity but will only do so when the electrodes are connected with something that conducts electricity. To make a connection attach the second aluminum strip to the part of the penny sticking out of the lemon with a plastic-coated paper clip.
Gather your materials. For this battery, you will need one unopened can of soda (any type will do), one plastic cup (6 to 8 ounces), and one 3/4-inch-wide strip of copper that's slightly longer than the height of the cup. In addition, you'll need a pair of scissors, a voltage meter, and two electrical lead wires with alligator clips at both ends.
An electric current is the flow of moving charges (usually in the form of electrons or ions) through an electric circuit. In a battery, the galvanic cell usually consists of two electrodes, usually made from metals or carbon, which are in contact with an electrolyte, as shown in Figure 2.
To make a similar battery in the lab you will need: 12 pencil leads (2B or softer), one for each cell, or you could use school laboratory 'carbon' rods, or salvage them by carefully dismantling old batteries.
