The anode is one of the two main electrodes in a battery, responsible for storing and releasing electrons during charge and discharge cycles. In most rechargeable batteries, including lithium-ion cells, the anode is the negative electrode during discharge and the positive electrode during charging (based on conventional current flow).
In lithium-ion batteries:
The anode is typically made of graphite, a form of carbon that can reversibly store lithium ions between its layers during charging (a process called intercalation).
During discharge, lithium ions move from the anode to the cathode through the electrolyte, while electrons flow through the external circuit to provide power.
During charging, lithium ions return to the anode from the cathode, where they are stored until the next discharge cycle.
