Description

Simple but powerful battery can be done using some materials from the kitchen: aluminum foil, paper for a membrane, active carbon for an air electrode, and an iron mesh for a current collector. The Al-air battery is more energy dense than a Li-ion battery.
In the chemical equation the redox potential should be -2.3 V instead of -1.66 V.
This aluminum-air battery was designed by Tavo Romann (PhD).
The preparation of the air cathode is described in the new version of aluminum-air battery video: http://youtu.be/fcLZ6dM-qIU
The carbon electrodes can be also obtained from http://www.superaccu.com
