The battery generates electrical current from

Chemical energy.

The electric battery generates electrical current through chemical energy. The battery is a device that generates electrical energy to be used in operating electrical appliances and many other devices. This battery stores chemical energy and then later converts it into electricity. This process falls under a science called chemistry. electrical.

The process is carried out through a single electrochemical cell or a group of cells, depending on the device used. The current depends on the number of cells used in generation, so batteries differ in their types according to the cells and the method of generating current. Each electrochemical cell consists of two electrodes separated by a specific electrolyte that helps complete this process. And its continuation.

The electricity that is produced from an electrochemical cell is the energy that is produced by the flow of a group of electrons. These electrons are produced through a chemical reaction that occurs at one of the poles of the cell and then flow to the other pole and there they are used, thus generating the current that flows between the poles continuously. .

The cell consists of two electrodes, one of which is positive and is called the cathode, and the other is negative or positive and is called the anode. In general, in all types of batteries and electrochemical cells, electrons are generated at the anode, i.e. the negative or positive electrode, and then they are transmitted in some way through a wire to the cathode, i.e. the positive electrode, and thus they are generated. Current in the battery.

What is the definition of battery?

It is a device consisting of one or more electrochemical cells used to operate electrical devices.

In physics and electrical devices, the battery is an electrochemical device, that is, it depends on electrical and chemical energy and the interactions between them. It consists of one or more electrochemical cells, and the battery can be charged with electric current and discharged when used and needed.

The cells that make up the batteries are connected to external inputs and outputs that facilitate their work in charging and discharging. Batteries are widely used in small electrical devices such as remote controls, phones, and some light bulbs. Batteries are classified into two categories: primary or primary batteries and secondary batteries, and each of them has features that distinguish it from the other in Properties and uses.

Primary or basic cells can only be charged once, and when they are discharged, this battery becomes useless and is disposed of. The reason is that the electrochemical reaction that occurs inside these batteries is non-reciprocal, that is, it only takes place once, then it stops, and then the battery stops.

This is in contrast to secondary batteries, which are batteries that can be used more than once, as we can charge them and reuse them again, because the reactions that occur inside them are reversible, and in them the reacting materials combine to form products, and when they are charged, electricity flows, which facilitates the flow of electrons to the battery, and this The reaction is a reversible reaction.

What type of electrical current comes out of the battery

DC current.

Direct current is a single-flow current, or a current that moves in one direction, and refers to the direction of moving and producing electrons, which is the form of energy that is produced by solar cells and batteries. Direct current is the opposite of alternating current, which reverses its direction but not periodically.

Direct current is widely used in batteries and in low-voltage devices and applications such as automobile applications, aircraft, and many applications that depend on low current. Currently, all solar panels produce direct current and can be converted to alternating current when the solar inverter is not used.

Direct current has advantages and disadvantages like anything, as one of the most important advantages of direct or direct current is its ability to operate special applications, especially when transmission of alternating current is not possible, or over long distances, and one of the most important applications is high-voltage subsea direct current transmission lines. .

Although the current is originally produced in the form of alternating current, the inability to transfer it forces specialists to convert it into direct current to facilitate its transfer, as it is converted at terminal stations using specific and specialized cables, an example of which is the cable connection called the Baltic cable connection between Sweden and Germany.

How does the battery work from the inside?

Through electrochemical reactions that take place inside it.

The battery consists of two electrodes, one negative or positive, and the other positive. The first, i.e. the anode, is responsible for generating electrons that then flow and then generate electrical current. However, there are questions about the anode obtaining all these electrons, which lead to generating current.

The anode obtains them through reactions, where the electrode interacts with the electrolyte, leading to the formation of electrons. At the same time, the cathode is prepared through certain reactions to receive the electrons that were formed at the anode.

The reactions that take place inside the electrochemical cell are called oxidation-reduction reactions, and they are the most common reactions. The entire reaction is divided into two parts. In the case of this battery, half of them occur at one electrode of the cell and the other half occur at the other electrode.

The process of oxidation occurs at the electrode that loses, which is the anode, while reduction occurs at the electrode that receives, because reduction means gaining electrons, and this electrode is the cathode. Any two conductive materials that have interactions, or standard interactions can occur between them, can form an electrochemical cell, then a current, then a battery and operation.

What are the battery sections?

• Anode.
• Cathode.
• Electrolyte.
• separator.
• Cover.

In order for a battery to be formed and work, this battery must consist of a group of components that interact with each other to form it, which are:

The anode:  It is one of the poles of the cell and it may be positive or negative, but in any case it is the one from which the electrons flow in the circuit due to the oxidation process that occurs in it through the loss of electrons, which are later gained by the cathode.

Cathode:  It is the second electrode of the cell in which the reduction process occurs, that is, the acquisition of electrons flowing from the anode, and its charge is positive, and the electrons reach from the anode to the cathode through the electrolyte or through an external circuit of the battery.

Electrolyte:  It is the liquid or gelatinous substance that is able to transfer electrons between the electrodes and then generate an electric current. It can be replaced with an external battery circuit through which the electrons flow.

Separator:  It can be one separator or several separators, which are porous materials that prevent any contact that may occur between the cell electrodes, so that a short circuit does not occur in the battery. Separators are made of several materials such as cotton, nylon, polyester, or carbon, and cannot be Separators interact with the anode or cathode because they are only responsible for separating them and not causing any change in the battery or conductivity.

Cover:  In order for the battery components to be contained in order to become a battery, there must be a cover, box, or shell, which are mechanical structures that contain the battery components and aim to stabilize the internal parts of the battery. Devices and structures can be made of several materials, such as plastic or steel bags.
