What is a battery? How does it work ?
Electrochemical equipment used to store and convert chemical energy into an electrical form is called a battery. The batteries consist of one or more electrochemical cells, such as fuel cells or flow cells.
The oldest known man-made batteries are those made in Baghdad. B.C. It is estimated to have been built between 250 and 640 AD. The development process began in 1800 with a Voltaic battery developed by an Italian physicist, Alessandro Volta. Worldwide, the battery industry has reached a turnover of US $ 48 billion in 2005, which is now very large.
In general, batteries are divided into two as Non-rechargeable and Rechargeable batteries. Disposable (non-rechargeable) batteries;
Zinc carbon; used in low-cost, low-energy processes,
Zinc chloride is used in processes that last less than zinc carbon battery,
Alkaline “long life lar used in processes that require more power,
Silver oxide; commonly used in hearing aids
Lithium; they are generally used in digital cameras and are widely used in watches and computer clocks.
Mercury; usually used in digital watches,
The thermal battery has a high temperature storage structure and is generally used in military applications.
Rechargeable;
The lead acid battery is charged and used continuously in vehicles, alarm systems and uninterruptible power systems.
Lithium ion; is quite common. High charging capacity. It is used in portable digital devices such as laptops, mobile phones, music players and many more.
The lithium-ion polymer has the basic characteristics of a lithium-ion battery, the difference being that it has less charge density.
Nickel metal hydride is used in all applications of Li-Ion and Ni-MH battery types. These types are able to be recharged many times (approximately 1500 times) but store less energy than other types.
The structure that the batteries come together to form is called a battery. It was widely used in lamp radio receivers before the 1960s. Today, they are widely used in portable computers. On the other hand, mobile phones used 3-cell batteries when they came out, but today almost all phone models use single-cell lithium-ion types, but we still call them batteries. You need a habit.
For over 250 years of development, batteries are among the most expensive sources of energy. It can contain very expensive products and even risky chemicals in its structure. For these reasons; because it contains chemical substances can affect human metabolism can have no unpleasant consequences. Nowadays, centers have been established in order to carry out studies for the recycling of toxic substances in used batteries.
It is possible to make batteries from lemon or other acid-containing fruits. These types are called voltaic batteries as a result of converting chemical energy into electrical energy. Batteries are made using the logic of placing two separate metals in an acidic solution. In this way, when a lemon, for example a zinc-plated nail and a copper coin is dipped, the lemon juice forms the required acid solution and can generate electricity, but the electrical energy produced is very weak and is light enough to provide a light glow even in LED lights.
