Hydrothermal synthesis mechanism and electrochemical performance of LiMn0.6Fe0.4PO4 cathode material

Monocrystal LiMn0.6Fe0.4PO4 cathode material was obtained via hydrothermal method at 180 °C for 10 h without any surfactant. The effects of hydrothermal time on the phase and morphology of the material were discussed. By controlling the reaction solutions, the rodlike, flowerlike, and strawlike LiMn0.6Fe0.4PO4 cathode materials were synthesized. Electrochemical performances show that the rodlike LiMn0.6Fe0.4PO4 has the best electrochemical properties. The initial discharge capacity of the rodlike structure is 106.4 mAh·g−1, which is higher than those of flowerlike and strawlike materials.
