This aluminum can battery uses paper towel to separate braided copper wire from the aluminum can. A sponge presses the copper close to the aluminum. The outer shield of copper coaxial cable wire was used for its large surface area.
The electrolyte is salt water which soaks into the paper towel and does not fill the entire can. 0.566 volts 196 mA were the typical readings, which were measured.
Four can batteries were wired in series to create 2.24 volts total, to light a green LED.
