Electrochemistry is the study of the relationship between electrical energy and chemical reactions. It deals with the transfer of electrons between substances and their chemical reactions. This subject provides the basis for understanding the behaviour of batteries, fuel cells, and other types of energy storage and energy-conversion systems.

Nernst equation is a fundamental equation in electrochemistry that predicts the voltage at which an electrochemical reaction takes place. It is used to calculate the standard electrode potential of an electrochemical cell and the voltage of a galvanic cell under non-standard conditions. Nernst equation is an important tool for understanding the behaviour of batteries and other electrochemical devices.
