Conjugated microporous polymers (CMPs) have been heralded as promising energy-storage materials with advantages such as chemical flexibility, porous structure, and environmentally friendliness. Herein, a novel conjugated microporous polymer was synthesized by integrating triazine, thiophene, and benzothiadiazole into a polymer skeleton, and the Li -storage performance for the as-synthesized polymer anode in Li-ion batteries (LIBs) was investigated. Benefiting from the inherent large surface area, plentiful redox-active units, and hierarchical porous structure, the polymer anode delivered a high Li storage capacity up to 1599 mAh g at a current rate of 50 mA g with an excellent rate behavior (363 mAh g at 5 A g ) and a long-term cyclability of 326 mAh g over 1500 cycles at 5 A g , implying that the newly developed polymer anode offers a great prospect for next-generation LIBs.
共轭微孔聚合物（CMPs）被誉为具有化学灵活性、多孔结构和环境友好性等优点的有前途的储能材料。在此，通过将三嗪、噻吩和苯并噻二唑整合到聚合物骨架中合成了一种新型共轭微孔聚合物，并研究了其在锂离子电池（LIBs）中作为合成聚合物阳极的锂存储性能。受益于其固有的大表面积、丰富的氧化还原活性单元和分级多孔结构，该聚合物阳极在50 mA g的电流速率下具有高达1599 mAh g的高锂存储容量，具有优异的倍率性能（在5 A g时为363 mAh g），并且在5 A g下经过1500次循环后具有326 mAh g的长期循环稳定性，这意味着新开发的聚合物阳极在下一代LIBs中具有广阔的前景。
