Study of hydrothermally synthesized LiFePO4 with different morphology

详细

Monodispersed LiFePO₄ particles with different morphology have been successfully obtained through hydrothermal method using same starting materials. The morphology of the as-synthesized LiFePO₄ particles were dependent on feeding sequence of starting materials. Different dissolution rate of solid phase in precursor prepared by reversing feeding sequence lead to different morphology. The half-cell using as-obtained LiFePO₄ with different morphology were assembled to investigate electrochemical performance. The results show that LiFePO₄ with nanorods morphology displays a higher initial discharge capacity and excellent cycle retention than the sample with microplates morphology.
