Lithium batteries consist of key components that work in tandem to produce electrical energy. These include a cathode, an anode, and an electrolyte. The cathode, typically constructed of lithium cobalt oxide, and the anode, made of graphite, serve as positive and negative terminals, respectively. The electrolyte, comprised of a lithium salt dissolved in an organic solvent, acts as a medium for the flow of lithium ions.
Lithium ions serve as the primary charge carriers within these batteries. During discharge, these ions move from the anode to the cathode, creating an electron imbalance which generates electrical current through an external circuit. Conversely, during charging, the flow of electrons is reversed, prompting the lithium ions to migrate back to the anode. This intricate process is the basis for the reliable and efficient operation of lithium batteries, which have become a critical source of power in many modern technologies.
