| Abstract: Using trimellitic acid and cobalt nitrate hexahydrate as raw materials, two cobalt-based metal-organic polymers (Co-MOP) with different reaction times were synthesized by the hydrothermal method. The structure and morphology of Co-MOP were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and N2 adsorption-desorption test. Two cobalt-based metal-organic polymer materials were used as anode materials for lithium-ion batteries, and the electrochemical performance tests were carried out. The results showed that Co-MOP-12 (hydrothermal reaction for 12 h) exhibited excellent electrochemical performance. The first-cycle reversible specific capacity the of Co-MOP-12 electrode reached 979 mAh·g-1 at a current density of 100 mA·g-1. The specific capacity was as high as 1 345 mAh·g-1 after 100 cycles. |
