What is a cathode material for lithium-ion batteries? Cathode material company rankings. Anode materials are one of the key materials that determine the performance of lithium-ion batteries, and they are also an important source of lithium ions in commercial lithium-ion batteries. Among the cathode materials, the most commonly used lithium-ion battery materials are lithium cobalt acid, lithium manganese acid, lithium iron phosphate and ternary materials. Lithium-ion battery cathode material. JPG What is a cathode material for lithium-ion batteries? 1. Lithium manganese manganate is a lithium-ion battery material with a long history of use. It has outstanding advantages such as high safety and strong resistance to overcharge. Due to the structural stability of lithium manganate, the number of cathode materials does not have to exceed that of the cathode too much. In addition, the material price is low, the production process requirements are relatively low, and the widely used cathode material has been obtained earlier. Lithium manganate is limited by its high-temperature performance, and is generally not used in high-power or high ambient temperature situations, such as high-speed passenger cars, and plug-in hybrid vehicles rarely choose lithium manganate as power. But for electric buses and local logistics vehicles, lithium manganese acid is completely capable. 2. Lithium iron phosphate The advantages of lithium iron phosphate are mainly reflected in safety and cycle life. The important determinant is the olivine structure of lithium iron phosphate. On the one hand, this structure reduces the ion diffusion capacity of lithium iron phosphate, and on the other hand, it also has better high temperature stability and good cycle performance. Lithium iron phosphate battery, due to its high safety, although the energy density partially affects its range of use, it is still an important power lithium-ion battery for electric vehicles in my country. In particular, national policies stipulate that buses must use lithium iron phosphate batteries, because this is related to the safety of many people. 3. Ternary lithium Ternary lithium cathode material combines the advantages of LiCoO2, LiNiO2, and LiMnO2 to form a synergistic effect within the same battery, taking into account the three requirements of stability, activity and low cost of the material structure. It has the highest energy density among the three important cathode materials. Its low temperature effect is also significantly better than lithium iron phosphate batteries. The market share of ternary lithium-ion battery cathode materials is gradually expanding, which is mainly driven by the pursuit of automobile mileage. In order to catch up or even exceed the driving range of gasoline-powered vehicles, electric vehicles must be equipped with as much power as possible in a limited space, which makes energy density particularly important.
