| Abstract: |
| Based on the development and research status of porous organic polymers and their derived carbon materials in anode materials of lithium-ion batteries, we explored a synthesis method of porous carbon nanospheres with controllable pore size. Firstly, we designed and synthesized a series of novel porous organic polymers with regular morphology using the 6,13-bis[bis（4-bromophenyl） methylene]-pentacene compound as the unit. The polymers with different pore sizes were carbonized at different temperatures to study the influence of carbonization temperature on the electrochemical properties of the material. According to the experimental data, the porous carbon material THF-800 has the best cycle stability and excellent magnification performance among the materials. Overall, the porous carbon material THF-800 has been proved to have the potential application value as the anode material in lithium-ion battery. Furthermore, the method we used to control the size of porous organic polymers can promote the application of organic materials in lithium-ion batteries, and finally expands the application of porous organic polymer-derived carbon materials in the anode materials of lithium-ion batteries. |
