Homemade aluminum-air battery I - high power

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 https://www.superaccu.com/energystorage.html See also our other electrochemistry experiments: Homemade supercapacitor https://youtu.be/gTt_YBzJ_Dk Microbial fuel cell https://youtu.be/_zCsAfEbVRc Making sodium https://youtu.be/eGnPQtai0og la batería de aluminio-aire 铝空气电池 bateria de alumínio-ar алюминиево-воздушной батарее Aluminium-Luft-Batterie batterie aluminium-air batteria di alluminio-air алюмінієво-повітряної батареї aluminium-õhk patarei
