What are the cathode and anode materials of ternary lithium batteries?

[DeJoel]

Currently, the main commercially used cathode materials include lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate. The anode material is basically graphite. The following is a related introduction about ternary lithium batteries: 1. Materials: "Lithium batteries" are a type of battery that uses lithium metal or lithium alloy as the anode material and non-aqueous electrolyte solutions. 2. Development history: Lithium metal batteries were first proposed and studied by Gilbert-N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal impose very high environmental requirements.

The cathode material of ternary lithium batteries is lithium nickel cobalt manganese oxide, meaning it is a compound composed of a mixture of three metals: nickel, cobalt, and manganese. The anode material is typically graphite, mainly composed of carbon. The cathode is responsible for releasing lithium ions during charging, while the anode absorbs and stores these ions, releasing them back during discharge to power devices or vehicles. This combination enhances the battery's energy density, prolonging the runtime of your phone or electric vehicle. However, the scarcity of cobalt drives up costs and poses supply challenges, so some designs adjust the ratios—for example, increasing the proportion of nickel to improve performance and stability. Overall, understanding these materials can help you maintain battery life and avoid risks like overcharging or overheating.

I often research mobile phone battery issues. The cathode of ternary lithium batteries uses lithium nickel cobalt manganese oxide material, while the anode has a graphite structure. The cathode acts like a starting point, controlling the flow direction of lithium ions; the graphite layers in the anode safely store them, ensuring efficient charging and discharging. This design offers many advantages, such as fast charging and high energy density, but overheating issues must be noted as the materials may become unstable at high temperatures. In automotive applications, it enables electric vehicles to travel longer distances, though aging of the anode graphite can affect overall battery health. Users are advised to regularly check device temperature and use original chargers to extend battery lifespan.

Devices that use ternary lithium batteries have a cathode made of nickel-cobalt-manganese ternary compounds, while the anode is typically graphite. The cathode is responsible for guiding the movement of lithium ions, and the anode acts like a storage tank to receive these ions. This combination makes the battery lightweight and efficient, suitable for portable electronics. Maintenance is simple—just avoid extreme environmental changes.
