Abstract A well‐designed solvothermal approach has been employed to synthesize olivine LiMn 0.5 Fe PO 4 (LMFP) cathode material with a nanoplate configuration. This method precisely controls crystal growth achieve high proportion of (010) facets while minimizing intrinsic defects. These modifications significantly enhance lithium‐ion diffusion kinetics and optimize the electrochemical performance LMFP. The nanoscale reduced anti‐site defect concentration in MP‐PRO sample functionalize jointly promote transport during long‐cycle. Furthermore, superior is closely linked impedance enhanced Mn redox kinetics. Both theoretical calculations experimental results indicate that confinement effect induced by 1,3‐propanediol directs facet orientation confines growth. Compared product synthesized using water (MP‐H 2 O), 1,3‐propanediol‐based (MP‐PRO) delivers specific capacity 130.7 mAh g −1 at 5C demonstrates excellent cycling stability, an 84.6% retention after 1000 cycles. study provides new insights into LMFP electrodes reveals effective electrode structure design realize long‐life rate batteries.
