Homemade Magnesium-Copper Battery Powers 1W LED!I built a magnesium-copper battery using a magnesium rod, copper wire, and saltwater (NaCl solution) as the electrolyte. The battery produces 1.9V, which is not enough to directly power a 1W LED.
Chemical Reactions in the Battery:
At the Magnesium Anode (-):
(Magnesium dissolves, releasing electrons into the circuit.)
At the Copper Cathode (+):
(Water is reduced, producing hydrogen gas and hydroxide ions.)
Overall Reaction:
(Magnesium reacts with water, forming magnesium hydroxide and releasing hydrogen gas.)
To boost the voltage, I made a simple DC-DC voltage booster using a D882 transistor, a 1kΩ resistor, and a small toroidal inductor. This circuit efficiently steps up the voltage, allowing the LED to glow brightly!
This experiment proves that even a basic homemade battery can generate useful power when combined with the right circuitry. Let me know your thoughts in the comments!
