Gradient Mg and Uniform Ti Co-Doping Suppresses Jahn-Teller Effect in LMFP via Optimized Ion-Transport Kinetics and Interfacial Reactions.
LiMn0.6Fe0.4PO4 (LMFP), an olivine-type cathode material, is gaining attention in high-energy-density lithium-ion batteries due to its high operating voltage and cost-effectiveness. However, its practical use is limited by slow Li+ diffusion, poor electronic conductivity, and structural degradation caused by Jahn-Telle...
