Electrochemistry is the science that studies the interconversion between electrical energy and chemical energy, covering the principles, kinetics, and interface behavior of electrochemical reactions. It is the theoretical foundation for understanding and designing devices such as batteries, electrolysis, electroplating, fuel cells, and supercapacitors. In the battery industry, electrochemistry constitutes the core mechanism of battery operation, which is to transfer electrons and ions between the anode and cathode through **redox reactions**, thereby achieving the storage and release of electrical energy.
