How to make a battery

the battery

Batteries have multiple shapes and sizes, to suit the shape and size of the devices, as well as to match the amount of energy required to operate the device, and the types of batteries have been divided into primary batteries, which are non-rechargeable batteries, as they are used once, and then disposed of, due to the consumption of materials The chemical component of it, during a chemical reaction, is irreversible, and is usually used in control devices. The second type is secondary batteries, which are batteries that are recharged a certain number of times, before being disposed of; Because the chemical reaction that takes place inside it is reversible, as it is reflected when an electric current is passed, which is the process of charging the battery, and it is used in devices that need high energy, such as: mobile phone batteries.

How to make a battery

• Placing any liquid or body, inside a solution of positive and negative ions, until the liquid or body is saturated with ions, and thus becomes like a liquid or a connecting body in the battery, and when connecting two different electrodes of metal in the body or liquid charged with ions, then connect them to the body that is intended to generate energy, Small amount of energy will be generated.
• A battery can also be made, by dipping two rods of two different metals in a potato or lemon, and connecting them with a wire. For example, making a potato battery. First, a potato must be divided into two halves, placed on a metal plate, taking into account that the cut half is in contact with the metal plate, then a nail must be inserted into one of the halves, and a nail made of another metal must be inserted into the half of the potato. the other, then connect the two screws by a wire, some electricity will be generated, which can light a small lamp.
• Or by using a cola can, first the contents of the cola can be emptied into another container, then the upper surface of the can is removed, by using a can opener, after that the can is dried, then cleaned using woolen wire to remove the plastic layer, (until the connection between The liquid and the inner surface of the can), and later the cola is returned to the can, then one of the wires of the cable is fixed with a coin, and the other wire is attached to the upper edge of the can, then the coin is thrown into the cola liquid, and thus some energy will be generated that is sufficient to operate a small lamp.

The energy produced by the battery depends on the form of connection, where connection in parallel increases the intensity of the current, but with the same value of the voltage difference, while connection in series increases the value of the voltage difference, but with the same current, and in the previous cases, the amount of energy can be increased by adding some salt to the liquid , until the amount of ions increases.
