Lithium Ion Battery Definition
Structure of Lithium Ion Battery
Lithium-ion batteries consist of three main components: anode, cathode and electrolyte. The anode usually uses a carbon-based material such as graphite. The cathode is made of lithium metal oxides. The electrolyte is in liquid or gel form containing lithium salts.

Working Principle
Lithium ion batteries work through charging and discharging processes. During charging, lithium ions move from the cathode to the anode. During this process, electrochemical reactions take place. While electrons reach the anode through the external circuit, lithium ions move within the electrolyte.
During the discharge phase, lithium ions return to the cathode. Energy is released during this process. Energy storage and release mechanisms enable the battery to operate efficiently. Thanks to electrochemical reactions, electrical energy is converted into chemical energy and recycled again.
