Experiments with galvanic power supplies

Hello everyone today I will try to make a galvanic power supply.

For this we need.

  • Copper wire
  • Aluminum wire
  • Galvanized nails
  • Capacities (many)
  • Salt, soda, acetic acid, water

Getting Started

To make galvanic batteries you need to understand what will give more electricity. Just because of this, I decided to do this, because in the future I want to make an emergency power supply to power an LED lamp or charge a phone.

Let's get started

At the end there will be a table with the results there will be the designation A1, A2, and so on. Here are my types of experiments E1 is copper and aluminum twisted together, poured with electrolyte. We can say this is a bad twisting of aluminum with copper, with poor insulation on which something corrosive has gotten. E2 twisting aluminum with copper but already with an intermediate layer of paper, they say that this gives half a volt, with electrolyte impregnation. E3 two electrodes made of aluminum and copper immersed in the electrolyte. E5.1 is the same as E3, but instead of aluminum, the nail is galvanized. And why E5 instead of E4 is because there are E3.1 and E4, but I didn't want to do them. E5.2 is the same as E5.1, but instead of a nail, aluminum and instead of copper, a nail. E6.1 is a graphite rod from an aluminum pencil in a container with electrolyte. E6.2 is E6.1, but instead of aluminum, copper.

Let's start

There will be four electrolytes. The first salt solution, the second soda solution, the third acetic acid, the fourth water. And the fifth has nothing to chase. Well, let's start the EXPERIMENT of twisting aluminum with copper, in salt water 0.05mV

It is interesting that the last two experiments, first from half a volt to 0, and then from 0 to half a volt, from polarity change. Here is a table of all the experiments.

Based on these experiments, I will make myself a 5V emergency power supply. In the meantime, I made a 3.5V battery.
