To choose the right battery types |
Posted: September 8, 2022 |
In this tutorial, we will learn about an important component in electrical and electronic systems: batteries. We will see some basic information about batteries, learn about different battery types and guide to battery types suitable for your application. Whether you are an electrical engineer or not, you may encounter at least several different battery types in your life. Some common places where you use batteries are wall clocks, alarms or smoke detectors that use small disposable batteries, or cars, trucks or motorcycles that use relatively large rechargeable batteries. In the past decade or so, batteries have become a very important energy source. Even before that, they have become an indispensable part of our lives, supplying power to a variety of portable devices such as transistor radios, walkmans, handheld game consoles, cameras and so on. But with the development of advanced smartphones, tablets, laptops, solar energy and electric vehicles, research on powerful batteries that can last longer and provide necessary energy has reached its peak.With different battery types,you can get good power. In fact, the 2019 Nobel Prize in chemistry has been awarded to three scientists, John B. goodenough, M Stanley Whittingham and Akira Yoshino, who developed lithium-ion batteries. A battery is a chemical device that stores electrical energy in the form of chemical substances and converts the stored chemical energy into direct current (DC) electrical energy through electrochemical reactions. In 1800, Italian physicist Alessandro Volta invented the first battery. Electrochemical reactions in battery types involve the transfer of electrons from one material to another by current (called electrodes). Although the term battery is often used, the basic electrochemical unit responsible for the actual storage of energy is called a battery. As mentioned above, a battery is a basic electrochemical unit and a source of electrical energy generated by chemical energy conversion. In its basic form, the battery types usually contain three main components: two electrodes and electrolyte, as well as terminals, separators and containers. Speaking of electrodes, there are two types of electrodes, called anodes and cathodes. The anode is a negative electrode (also referred to as a fuel electrode or a reduction electrode). It loses electrons to an external circuit and is oxidized in an electrochemical reaction. On the other hand, the cathode is a positive electrode (also referred to as an oxidation electrode). It accepts electrons from an eternal circuit and is reduced in an electrochemical reaction. Therefore, the energy conversion in the battery is due to electrochemical redox reactions. The third important component of the battery is the electrolyte. The electrolyte acts as a medium for transferring charge in the form of ions between the two electrodes. Therefore, electrolytes are sometimes referred to as ionic conductors. An important point to note here is that the electrolyte is not conductive, but only ionic conductive. Batteries are usually composed of one or more "batteries", which are electrically connected in series or parallel configuration to provide the necessary voltage and current levels.
