Typical Application
The primary example of a battery electrochemistry application is the charging and discharging of lithium-ion battery cells. During a charging cycle, the lithium ions are extracted from the active particles of the positive electrode (cathode). The ions move through the electrolyte by migration and diffusion from the positive electrode to the negative electrode across the separator. At the negative electrode (anode), the ions intercalate into the active particles. Heat is generated during the flow of electrons, ion migration, and the intercalation process. During discharge, the cycle is reversed.
