The battery materials used influence the intercalation process. Lithium-ion batteries use lithium ions (Li +), while sodium-ion batteries use sodium ions (Na +). The chemistry and structure of the cathode is selected to enhance the discharge rates and overall capacity of the battery. The intercalation process is dependent on the cathode and is the foundation for how batteries work.
Three basic battery types are used in 2020s-era electric vehicles: cylindrical cells (e.g., Tesla), prismatic pouch (e.g., from LG), and prismatic can cells (e.g., from LG, Samsung, Panasonic, and others). Lithium-ion flow batteries have been demonstrated that suspend the cathode or anode material in an aqueous or organic solution.
Interestingly, this material demonstrated superior air stability contrary to other reported O3 cathode materials, which might be attributed to the fact of formation of a new surface that protected the bulk material from direct atmospheric contact.

The material contents of the cathode make up about 50% of the battery cell cost. In other words, the Cathode Active Material (CAM) makes up 8-10% of the cost of an EV. CAM is so expensive due to the high costs of mining and refining materials, along with the global supply chain needed today to transport the CAM to battery cell manufacturers.

The cathode, anode, and electrolyte are the most important active materials that determine the performance of a Li-ion battery. As anode materials offer a higher Li-ion storage capacity than cathodes do, the cathode material is the limiting factor in the performance of Li-ion batteries , .
Alternatively, matching organic cathode materials with suitable inorganic cathode materials can effectively eliminate the dead weight of the latter, particularly the binders, improving not only the energy density but also the rate capability of the inorganic cathode material based LIBs. 13, 139 Fourth, most organic cathode materials exhibit redox potentials around 2.5 V versus Li/Li +
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the Li-ion battery cell. The anode is usually made out of porous lithiated graphite. The electrolyte can be liquid, polymer, or solid.
While the cathode material in lithium-ion batteries is well optimized, the anode material can be enhanced and today's research is focused on this particular area. The anode of a lithium-ion battery has an active material. It consists of cobalt, nickel and manganese, presented in a crystalline structure, forming a polymetallic oxide material.
Cathode materials The positive electrode, known as the cathode, in a cell is associated with reductive chemical reactions. This cathode material serves as the primary and active source of most of the lithium ions in Li-ion battery chemistries (Tetteh, 2023).
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.
Cathode materials play a pivotal role in the performance, safety, and sustainability of Li-ion batteries. This review examined the widespread utilization of various cathode materials, along with their respective benefits and drawbacks for specific applications. It delved into the electrochemical reactions underlying these battery technologies.
