This study investigates the effects of different titanium doping concentrations on properties iron phosphate precursors and final lithium (LiFePO4) materials, aiming to optimize structural electrochemical performance LiFePO4 by introducing during precursor synthesis stage. Titanium was introduced using titanate as a source prepare with varying concentrations. The materials were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), other techniques. results showed that incorporation significantly influenced Fe P content in precursors, decrease both levels concentration increased. Moreover, increased, particle size decreased, distribution became more uniform. Additionally, improved tap density significant increase observed when reached 4000 ppm. Electrochemical measurements revealed had certain impact discharge capacity LiFePO4, gradually decreasing Overall, this effectively physical stage, providing theoretical foundation for further optimization titanium-doped LiFePO4.

Here, the effects of Mg2+, Mn2+, and SO42- impurities in FePO4 raw materials on properties LFP were studied by converting into doping elements. The results indicate that due to differences ionic radius methods, these three have varying impacts performance LFP. 0.2-0.6% Mg2+ can significantly improve high-rate capacity cycle materials. At 5 C, discharge specific reaches 122.39 mAh/g, respectively, retention rate is 94.7% after 500 cycles. By contrast, Mn2+ leads a significant decline decomposed reduced during synthesis, which slightly reduces electrochemical Therefore, it not case higher purity yields better results. An appropriate amount should be retained, controlled at low level, minimized. Different treated differently reduce preparation cost material.
