Abstract LiFePO 4 is extensively used as a cathode material in lithium‐ion batteries because of its high safety profile, affordability, and extended cycle life. Nevertheless, inherently low transport kinetics restricted electronic conductivity considerably limit rate performance. Furthermore, the failure mechanisms specific to various cycling rates are not well examined. This study presents functional interface layer designed regulate rate‐dependent behavior . At elevated charge/discharge rates, this facilitates mobility, decreases internal polarization, alleviates mechanical stress, reduces structural degradation. lower it contributes formation stable cathode‐electrolyte interphase (CEI), effectively suppressing side reactions minimizing active lithium loss. Consequently, modified demonstrates enhanced stability capacity retention, with retention after 400 cycles at 2C increasing from 76.5% 98.6% 5C 40.2% 90.0%. Through combinations experimental data theoretical analysis, elucidates key underlying rate‐specific regulation, providing valuable insights into relationship between ion dynamics stability. approach represents an effective strategy for supporting potential use advanced energy storage systems that require both rapid charging prolonged
