| Abstract Scope |
In this study, LiFePO4/C material were prepared using a novel multi-step temperature controlled solid-phase method. The phase, morphology and electrochemical performance of the material was characterized using XRD and FESEM and constant current charging and discharging methods. The results showed that the synthesized material had a olivine structure, with spherical particles. The discharge specific capacity could reach to 163 mAh g-1 at the current density of 0.1C, and the capacity retention rate was 94% after 100 cycles at 1C. The material particles prepared by multi-step temperature-controlled synthesis method have a smaller size (50-100nm), and the secondary particles exhibit a porous morphology, which is compared with materials obtained from conventional method. Nanoscale particle size morphology is prone to lithium-ion migration, while porous materials facilitate sufficient infiltration of the electrolyte, resulting in excellent electrochemical performance of the material. |
