Abstract: Porous structure LiFePO4/C was synthesized by using triblock copolymer P123 as template combined with the self-assembly method. The crystal structure and electrochemical performance of synthesized samples were characterized by XRD, SEM, Nitrogen adsorption-desorption test, and charge-discharge test. The structure and electrochemical performance of the samples synthesized at different calcination times were studied. Results showed that the porous structure LiFePO4/C sample prepared at 700 ℃ for 12 h had the best electrochemical performance, the first discharge capacity was 151.27 mAh·g-1 at 0.1C rate, and its electrochemical performance was better than the LiFePO4/C sample without porous structure.
