What is a battery and how does it work?
The term battery has evolved to indicate the product powering a device regardless of the fact that it contains one or more cells. A cell converts chemical energy into electrical energy by virtue of electrochemical reactions occurring at its electrodes.
What is a basic battery concept?
Chapter 1 BASIC BATTERY CONCEPTS 1.1. Cells and Batteries: Components A cell is the basic electrochemical unit converting the chemical energy stored in it into electrical energy. A battery is composed, strictly speaking, of two or more such cells connected in series or parallel.
What are the components of a battery?
There are three main components of a battery: two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals. The electrolyte is a chemical medium that allows the flow of electrical charge between the cathode and anode.
What is a battery used for?
Batteries are commonly used to power small electric devices such as mobile phones, remote controls, and flashlights. The term "battery" has always referred to the combination of two or more electrochemical cells. A battery is made up of one or more electrochemical cells that convert stored chemical energy into electrical energy.
What are the characteristics of a battery?
Usually, we use the term battery for a combination of a few cells that are similar in nature. A practical battery must have the following characteristics: It must be light in weight and compact in size. The cell or a battery must be able to give a constant voltage. Moreover, the voltage of the battery or the cell must not vary during the use.
What is the basic principle of battery?
To understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electrons affinity. Actually, when two dissimilar metals are immersed in an electrolyte, there will be a potential difference produced between these metals.
