Blending Lithium Nickel Manganese Cobalt Oxide with Lithium Iron Manganese Phosphate as Cathode Materials for Lithium-ion Batteries with Enhanced Electrochemical Performance

The effects of LiMn0.7Fe0.3PO4/C (LMFP) species on the electrochemical performance blended cathodes LiNi0.5Mn0.3Co0.2O2 (NMC) and LMFP are examined. Two types LMFPs synthesized by hydrothermal method (LMFP-1) solid-state reaction (LMFP-2) leading to different physical characteristics uniformity primary particles. NMC LMFP-1 show higher discharge capacity, gravimetric energy density, rate capability than those LMFP-2 for same blending ratio (10, 20, 30, 40, 50 wt% NMC) because differences in electronic conductivity, specific surface area, mean particle size, particles between LMFP-2. capacity density : = 9 1 8 2 at 0.2 C-rate comparable NMC. Further, is highest 7 3. An optimal range revealed based cathode. Moreover, has a considerable impact LMFP.
