3. How Lithium Ion Batteries Work

Lithium-ion batteries operate through a complex electrochemical process. Each cell consists of an anode (typically made from graphite), a cathode (usually composed of lithium metal oxide), and an electrolyte that facilitates the movement of lithium ions between the anode and cathode.
When charging, lithium ions move from the cathode to the anode, where they are stored. During discharge, the process reverses, allowing the flow of ions back to the cathode, generating electrical energy. This continuous cycle of charging and discharging is what enables lithium-ion batteries to power numerous devices efficiently.
