Electric current is generated when lithium ions migrate from the negative electrode (anode) to the positive electrode (cathode) through the electrolyte during discharge. Reversing this
When a lithium-ion battery is charged, the lithium atoms at the positive electrode lose electrons and oxidize to lithium ions. Lithium ions swim to the negative electrode via the electrolyte, enter the storage compartment of the negative electrode, and gain an electron, reducing to lithium atoms. When discharging, the whole procedure is reversed.
Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode.
For example, traditional silicon materials undergo volume changes during the charging and discharging process, and the volume expansion rate is very high, which can cause damage to the electrode
In the search for high-energy density Li-ion batteries, there are two battery components that must be optimized: cathode and anode.

In a battery, the positive electrode (Positive) refers to the electrode with relatively higher voltage, and the negative electrode (Negative) has relatively lower voltage.
Although the electrode materials have an important action in rechargeable batteries, there are stringent requirements for the various components of an idealized commercial battery. Therefore, appropriate cathode, anode, electrolyte, binder, separator etc. play irreplaceable roles in improving battery performance.
In a battery, the positive electrode (Positive) refers to the electrode with relatively higher voltage, and the negative electrode (Negative) has relatively lower voltage. For example, in an iPhone battery, the voltage of lithium cobalt oxide (LiCoO2) is always higher than that of graphite, thus LiCoO2 is the positive electrode material, while

The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
The positive electrode has a higher potential than the negative electrode. So, when the battery discharges, the cathode acts as a positive, and the anode is negative. Is the cathode negative or positive? Similarly, during the charging of the battery, the anode is considered a positive electrode.
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?
The anode is one of the essential components of the battery. It is a negative electrode which is immersed in an electrolyte solution. So, when the current is allowed to pass through the battery, it oxidizes itself, and the negative charges start to lose and travel towards the positive electrode. What is the Battery Cathode?
Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode. Cathode active material in Lithium Ion battery are most likely metal oxides. Some of the common CAM are given below
In contrast to the anode, the cathode is a positive electrode of the battery. It gets electrons and is reduced itself. Moreover, the cathode is immersed in the battery's electrolyte solution. So, when the current is allowed to pass, the negative charges move from the anode side and reach the cathode.
