In traditional "lead-acid" batteries, the electrodes are lead and lead (IV) oxide. During discharge, both electrodes dissolve in the strong acid electrolyte to form dissolved lead (II) cations. During recharge, these reactions are reversed. Other battery types, with a longer rechargeable life are used for hybrid electric-gasoline cars.
Lead (Pb) is commonly used in electrodes in car batteries as it forms lead-acid batteries, which are known for their reliability and low cost. Lead is a heavy metal that can store and release electrical energy efficiently in this application.
electrodes
it will be useless to use 3 electrodes. IT IS WASTE OF MONEY.Two , three or four electrodes can be used but it only increases the rate of reaction.
A voltage of 12 V - as used in car batteries - is not particularly dangerous. You can even touch the electrodes, though I suggest not to touch BOTH electrodes at once.
Lead is commonly used to make the electrodes in automobile batteries. Lead-acid batteries are the most common type of battery found in cars, and they consist of lead dioxide as the positive electrode and sponge lead as the negative electrode.
The mineral mixed with clay to make pencil lead is graphite. Graphite is also used as a lubricant for machine parts and as electrodes in batteries due to its ability to conduct electricity.
Lead is used for - ballast keel of sailboats - in scuba diving weight belts - in small arms ammunition and shotgun pellets - in electrodes in the lead-acid batteries - in car batteries - in glazing bars for stained glass or other multi-lit windows
Lemon batteries can generate electricity by using the acid in the lemon as an electrolyte and the metal in the electrodes as conductors. When the electrodes are inserted into the lemon, a chemical reaction occurs that creates a flow of electrons, generating a small amount of electricity. Multiple lemon batteries can be connected in series to increase the voltage and power output.

Normally Lithium Ion batteries or Lead-Acid batteries.
