Activated Carbon Battery cell is an easy DIY project that can be made at home by using aluminum foil and the activated carbon. Activated carbon is used in the battery to increase the efficiency of dry cells with less weight and low energy density.

Materials need to build Activated Carbon Battery cell

  • Aluminum foil
  • activated carbon
  • paper
  • salt water
  • conducting wire
  • clip
  • LED
  • motor

Note: if you don't find activated carbon in store or any shop you can get from home water filtration plant shop activated carbon used in filters so you can get easily

ProcedureActivated Carbon Battery cell

  1. Cut several pieces of aluminum foils in 10cm square.
  2. Wet paper with salt water and put on the aluminum foil.
  3. Put activated carbon put on the next foil.
  4. Again put the aluminium foil over it.
  5. Pile it up to the three sets.

The aluminum foil on the charcoal side is anode while the other aluminum foil is cathode. Since the activated carbon is separated and it has bad contact. We need to push it downwards by the hand to generate electricity.

Science

Aluminum reacts with the salt water and releases the electron. The electron flows through the circuit and comes to charcoal. The electrons are absorbed by oxygen that was initially adsorbed at the surface by charcoal from the air. Here occurs oxidation and reduction. The electric current keeps flowing until the  oxygen contained in charcoal is lost or aluminum is dissolved.
