Researchers at the Massachusetts Institute of Technology recently announced a new discovery of long cycle life and high power lithium iron phosphate (LiFePO4) cells. Researchers at the Massachusetts Institute of Technology (MIT) found that solid-solution regions (SSZ) were formed at the boundary between lithium-rich and lithium-poor during charging of lithium iron phosphate battery electrodes, and charge activities were more concentrated in this region, Because lithium ions are released from the electrode. This finding will help researchers and manufacturers make better-performing batteries because of the better understanding of electrode material dynamics and further optimization. Lithium iron phosphate (LFP) electrode charge or discharge process diagram. Since lithium ions are separated during charging to form an iron-depleted (FP) iron (FP) region but with a solid solution region (SSZ, dark blue-green) between them, this region contains some randomly distributed lithium atoms , An ordered array different from the original crystalline material of lithium atoms (light blue). The above finding helps to solve one long-standing problem with lithium iron phosphate batteries: In the bulk form of crystals, the ionic conductivity of lithium iron phosphate and iron phosphate (FePO4 is separated during charging) is poor. However, this material exhibits a very high charge rate when doped and carbon coated optimized and nanoparticles used in the cell. The solid solution region resembles a "sub" state that can last for at least a few minutes at room temperature to replace the lumenal interface between LiFePO4 and FePO4. The ocher interface has been shown to contain many extra line defects known as "dislocations" Like a buffer, reducing the amount of "misalignment" prevents it from moving forward along with the electrochemical reaction.
