| Popis: | Blended spherical cathodes of lithium iron phosphate with different morphology were prepared using a physical mixing method. The lithium iron phosphate spherical material with high tapped density and non-spherical lithium iron phosphate material with good processing properties were compounded in different proportions. The processability and electrochemical properties of blended spherical cathodes were systematically investigated. The characterization results suggest that the blended spherical cathode material not only exerts the complementary advantages of the spherical and non-spherical material, but also produces a synergistic effect, which improves the processing property of the spherical material. This unique property reduces the internal resistance of the contact between the particles, thereby reducing the internal resistance of battery and improving the overall performance of battery. |
