The standard operating voltage of a battery is indicated by a reference value known as nominal voltage. It is a standardized measurement that illustrates the voltage range in which a battery typically functions.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
A normal alkaline cell, for instance, has a nominal voltage of 1.5 volts, while a typical lithium-ion cell has a nominal voltage of 3.7 volts. It is crucial to understand that a battery's nominal voltage is used to classify and compare batteries, whereas the actual voltage of a battery changes during the course of its discharge cycle.
It is a standardized measurement that illustrates the voltage range in which a battery typically functions. A normal alkaline cell, for instance, has a nominal voltage of 1.5 volts, while a typical lithium-ion cell has a nominal voltage of 3.7 volts.
A battery is an electrochemical device that produces a voltage potential when placing metals of different affinities into an acid solution (electrolyte). The open circuit voltage (OCV) that develops as part of an electrochemical reaction varies with the metals and electrolyte used.
