The impact of lithium iron phosphate positive electrode material on battery performance is mainly reflected in cycle life, energy density, power density and low temperature characteristics. 1. Cycle life The stability and loss rate of positive electrode materials directly affect the cycle life of lithium batteries.
Since several locations react in the actual charging process simultaneously, as the continuous deintercalation of lithium ions, the areas of each spherical FP continue to expand, causing these areas to contact or even cross each other, and finally, the reaction concludes.
Lithium iron phosphate is an important cathode material for lithium-ion batteries. Due to its high theoretical specific capacity, low manufacturing cost, good cycle performance, and environmental friendliness, it has become a hot topic in the current research of cathode materials for power batteries.
When discharging, the reverse process happens, and lithium ions are intercalated into the material from the electrolyte. The intercalation sequence of lithium ions proceeds from the outside to the inside along the radial spherical reaction interface.
