What is the effect of the positive electrode material on the performance of the lithium-ion battery

①Battery energy density Each lithium-ion battery positive electrode material has its theoretical energy density. When a positive electrode material is selected, the upper limit of the battery energy density is selected. The amount design of the positive electrode material and the tap density in the process of processing and construction also have an impact on the energy density of the battery cell product. ②The type of positive electrode material with different cell power density determines the general category of lithium-ion battery charge and discharge power. Some details of the material, as a help factor, will also affect the power characteristics. For example, the invariance of the crystal layout of the cathode material, particle size, doping atoms, carbon coating process, material preparation methods, etc. The above factors ultimately affect the power density of lithium-ion batteries by affecting the ability of the positive electrode material to contain lithium ions and the patency of the deintercalation and insertion channels. ③There are many factors that affect the life of the battery cell cycle life, related to the material of the positive electrode, the important ones are the loss of the active material of the positive electrode material in the cycle utilization, and the collapse of the material layout during the charging and discharging process, the positive electrode is excited to accommodate lithium ions. Attenuation of power. The impurities in the positive electrode material are like elemental iron and trivalent iron. The city and the electrolyte are used for each other, which presents undesirable side effects, which may cause internal micro short circuits.
