Make a 4.5V Aluminum Air Battery - EP.2
In this video I will make a 4.5v aluminum air battery using carbon plates, KOH solution and aluminum plate. This is an upgraded version with a maximum amps per cell of 120mA.
This experiment is known, can be replicated easily and without danger. Required: salt water, activated carbon for aquariums, aluminum foil 200x150 mm, two contacts of copper wire, soft paper, 2-3 volt motor. The battery has a capacity of about 35-40mA.
The 2-3 volt motor can be recovered from "cd rom motor".
To guarantee the success of this experiment, it is necessary to have a motor with a low energy consumption of 15-20 mA max. and a voltage of 2-3 volts. The use of all types of toy engines is not recommended.
* The operating time of the fan is about 20 minutes.
