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.
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.
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.
Batteries are designed so that the energetically favorable redox reaction can occur only when electrons move through the external part of the circuit. A battery consists of some number of voltaic cells. Each cell consists of two half-cells connected in series by a conductive electrolyte containing metal cations.
[ 3 ] Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices.
Fig. 13.2 shows the current conventional battery structure. Ion sources (anodes), separators, and electrodes (cathodes) comprise an electrochemical cell. Anodes emit positive ions that allow electrons to be obtained from oxidation to reach a separator and be supplied to an external circuit.

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those neg…

Battery
Batteries are designed so that the energetically favorable redox reaction can occur only when electrons move through the external part of the circuit. In simple terms, each battery is designed to keep the cathode and anode separated to prevent a reaction. The stored electrons will only flow when the circuit is closed.
