The cathode is the positive electrode, where reduction (gain of electrons) occurs, while the anode is the negative electrode, where oxidation (loss of electrons) takes place. During the charging process in a battery, electrons flow from the cathode to the anode, storing energy that can later be used to power devices.
In lithium-ion batteries, the anode is also negative when discharging. The primary material used for this electrode is graphite. Lithium ions move from cathode to anode during charging and intercalate into graphite layers. The reaction at the anode can be represented as: Li⁺ + e⁻ + C → LiC₆
While the lithium-ion anode is present opposite to the cathode, it has a negative charge. Hence, it undergoes an oxidation reaction during the charging and discharging of the battery. What Is Lithium Battery Anode Materials?
What are Cathode and Anode for a lithium battery？ The negative electrode in a cell is called the anode. The positive side is called the cathode. During charging, the lithium ions move from the cathode, through the separator, to the anode. During discharge, the flow reverses.
Despite this, in discussions of battery design the negative electrode of a rechargeable cell is often just called "the anode" and the positive electrode "the cathode". In its fully lithiated state of LiC 6, graphite correlates to a theoretical capacity of 1339 coulombs per gram (372 mAh/g).
When a Li-ion battery is charged, the active material on the positive electrode releases part of its Li ions, which flows through the electrolyte to the negative electrode and remains there, storing energy in the battery. When the battery is discharging, the opposite processes occur.
