What you will need:
Saucer
Scissors
Scotch tape
Six copper coins
Warm salt water
Two wires
Nippers (Knife)
Aluminium foil
Paper napkin
1 step
A little more theory:
The battery case, which is made of zinc, can be covered on the outside with cardboard or plastic. There are chemicals in the form of a paste inside the case, and some batteries have a carbon core in the middle. If the battery's power drops, it means the chemicals have been used up and the battery is no longer able to produce electricity.
Step 2
Actually, electricity in a battery is produced by combining aluminum, salt and copper.
Step 3
So let's get started!
To make a battery, you first need to clean the coins with a cleaning solution. Next, draw 6 circles on the foil and napkin and cut them out. Carefully strip the ends of the wires with wire cutters or a knife. Twist the veins. Attach one wire to the coin with electrical tape (scotch tape), and the other to the foil circle. Immerse a paper circle in a warm salty solution. Then put the wire with a circle of foil in a saucer. Place a wet paper circle on it and place a coin on top. Add several more layers of foil, damp paper and coins. Place a coin with a wire on top. The battery is ready!
This miracle worked for two hours, thoroughly oxidizing the coins.
Of course there were tears of energy, but the experience was interesting.
Humanity did not even notice how it gradually turned into a generation of “sissies.” Agree: you and I have simply become super-dependent. First of all, from technology. Thanks to progress, most of us will immediately panic if we find ourselves somewhere without a phone or, for example, with a dead flashlight. We believe that you need to be prepared for any turn of events. That’s why we continue to replenish your knowledge base with various survival life hacks. And today we’ll tell you how to make a battery out of coins.
You never know when you'll need an extra battery. So, if we are so gadget-dependent, it is better to get into the habit of always carrying an external battery with us. And also remember how to make a battery yourself practically in the wild. For example, from a handful of coins.
You will need:
1. Several copper coins;
2. Cardboard;
3. Foil;
4. Wires;
5. Scotch tape;
6. Vinegar;
7. Salt
First, dissolve 2-3 tablespoons of salt in vinegar, stirring vigorously. Place coins in a container with the solution to remove dirt, and then wipe with a napkin.
Place the coin on the cardboard and trace the outline. Make nine of these round stencils and cut them out.
Now we put the cardboard rounds into a container filled with vinegar. Let them soak there for about two minutes.
In the meantime, let's take care of the foil. Fold the sheet several times, place a coin on it, trace it along the outline with a pen or pencil, and cut it out. You need the same number of circles as cardboard ones.
Let's move on to the main part. Time to mix all the ingredients into a single “sandwich”. To begin, take out the cardboard rounds from the vinegar and blot the remaining liquid with a napkin. Now place a coin, a cardboard round on it, and a foil circle on top. On it - the next coin and further according to the same algorithm.
Take a double wire. Connect one end to the “bottom” of our coin tower, and the other to the “roof”. Wrap the structure well with tape.
What you will need:
Saucer.
Scissors.
Scotch tape (electrical tape).
Six copper coins.
Warm salt water.
Two wires.
Nippers (knife).
Aluminium foil.
Paper napkin.

How to make a Battery from coins?
Of course there were tears of energy, but the experience was interesting. 
A battery or galvanic cell is a chemical source electric current. All batteries sold in stores essentially have the same design. They use two electrodes of different compositions. The main element for the negative terminal (anode) of salt and alkaline batteries is zinc, and for their positive terminal (cathode) is manganese. The cathode of lithium batteries is made from lithium, and a variety of materials are used for the anode.
The electrolyte is located between the electrodes of the batteries. Its composition is different: for salt batteries, which have the lowest resource, ammonium chloride is used. Alkaline batteries use potassium hydroxide, while lithium batteries use an organic electrolyte.
When the electrolyte interacts with the anode, an excess of electrons is formed near it, creating a potential difference between the electrodes. When an electrical circuit is closed, the number of electrons due to chemical reaction is constantly replenished and the battery maintains current flow through the load. In this case, the anode material gradually corrodes and breaks down. When it is completely used up, the battery life is exhausted.
Despite the fact that the composition of the batteries is balanced by manufacturers to ensure long and stable operation, you can make the battery yourself. Let's look at several ways you can make a battery with your own hands.
Method one: lemon battery
This homemade battery will use a citric acid-based electrolyte found in lemon pulp. For electrodes we will take copper and iron wires, nails or pins. The copper electrode will be positive, and the iron electrode will be negative.
The lemon needs to be cut crosswise into two parts. For greater stability, the halves are placed in small containers (glasses or shot glasses). It is necessary to connect the wires to the electrodes and immerse them in the lemon at a distance of 0.5 - 1 cm.
Now you need to take a multimeter and measure the voltage on the resulting galvanic element. If this is not enough, then you will also need to make several identical lemon batteries with your own hands and connect them in series using the same wires.
Method two: a jar of electrolyte
To assemble a device with your own hands, similar in design to the world's first battery, you will need a glass jar or glass. For the electrode material we use zinc or aluminum (anode) and copper (cathode). To increase the efficiency of the element, their area should be as large as possible. It would be better to solder the wires, but the wire will have to be attached to the aluminum electrode with a rivet or bolted connection, since it is difficult to solder.
The electrodes are immersed inside the can so that they do not touch each other, and their ends are above the level of the can. It is better to secure them by installing a spacer or a cover with slots.
For the electrolyte we use an aqueous solution of ammonia (50 g per 100 ml of water). An ammonia aqueous solution (ammonia) is not the ammonia used for our experiment. Ammonia (ammonium chloride) is an odorless powder white, used in soldering as a flux or as a fertilizer.
The second option for preparing the electrolyte is to make a 20% sulfuric acid solution. In this case, you need to pour the acid into the water, and in no case vice versa. Otherwise, the water will instantly boil and its splashes, along with the acid, will get on your clothes, face and eyes.
When working with concentrated acids, it is recommended to wear safety glasses and chemical-resistant gloves. Before making a battery using sulfuric acid, it is worth studying in more detail the safety rules when working with aggressive substances.
All that remains is to pour the resulting solution into the jar so that there is at least 2 mm of free space left to the edges of the vessel. Then, using a tester, select required amount cans.
A self-assembled battery is similar in composition to a salt battery, as it contains ammonium chloride and zinc.
Method three: copper coins
The ingredients for making such a battery yourself are:
- copper coins;
- aluminium foil;
- thick cardboard;
- table vinegar;
- wires.
It is not difficult to guess that the electrodes will be copper and aluminum, and an aqueous solution of acetic acid is used as the electrolyte.
Coins first need to be cleaned of oxides. To do this, you will need to briefly dip them in vinegar. Then we make circles from cardboard and foil according to the size of the coins, using one of them as a template. We cut out the mugs with scissors, put the cardboard ones in vinegar for a while: they should be saturated with electrolyte.
Then we lay out a column of ingredients: first a coin, then a cardboard circle, a foil circle, a coin again, and so on until the material runs out. The final element should again be a copper coin. You can solder wires to the outer coins in advance. If you don’t want to solder, then the wires are attached to them, and the entire structure is tightly wrapped with tape.
During the operation of this DIY battery, the coins will become completely unusable, so you should not use numismatic material that is of cultural and material value.
Method four: battery in a beer can
The anode of the battery is the aluminum body of a beer can. The cathode is a graphite rod.
Additionally you will need:
- a piece of foam more than 1 cm thick;
- coal chips or dust (you can use what is left from the fire);
- water and regular table salt;
- wax or paraffin (candles can be used).
You need to cut it off the can top part. Then make a circle of foam plastic the size of the bottom of the jar and insert it inside, having previously made a hole in the middle for the graphite rod. The rod itself is inserted into the jar strictly in the center, the cavity between it and the walls is filled with coal chips. Then an aqueous solution of salt is prepared (3 tablespoons per 500 ml of water) and poured into a jar. To prevent the solution from spilling out, the edges of the jar are filled with wax or paraffin.
You can use clothespins to connect the wires to the graphite rods.
Method five: potatoes, salt and toothpaste
This battery is disposable. It is suitable for starting a fire by short-circuiting wires to produce a spark.
To create a potato lighter you will need:
- large potato;
- two copper wires in insulation;
- toothpicks or similar thin slivers;
- salt;
- toothpaste.
Cut the potato in half so that the cut plane has the largest possible area. Use a knife or spoon to select a hole in one half, pour salt into it and add toothpaste. Mix them together until a homogeneous mass is obtained. The amount of “electrolyte” should be level with the edges of the recess.
In the other half, which will be the top, we pierce two holes at some distance from each other so that they both fall into the recess with the electrolyte when assembling the “battery”. We insert wires into the hole, previously stripped of about a centimeter of insulation. Place the halves together so that the ends of the wires are dipped into the electrolyte. Use toothpicks to secure the halves together.
We wait about five minutes, after which, by connecting the wires to each other, you can strike a spark and start a fire.
All the methods described above are not a full replacement for a battery purchased in a store. The voltage on homemade elements can fluctuate and its value cannot be adjusted accurately. You won't be able to use them for a long time either. But somewhere in the wilderness, in the absence of electricity, assemble a battery with your own hands for mobile phone or an LED light bulb, everyone is quite capable. Naturally, if you have the appropriate materials at hand.
Ways to make a battery at home are a good illustration of how galvanic cells work. Assembling them with your own hands is available to schoolchildren in physics lessons.
