Conjugated microporous polymers exhibit great application prospects in lithium-ion battery electrode materials due to the cross-linked porous skeleton and highly conjugated structure. In this work, redox-active conjugated microporous polymers TZF and TBFZ were prepared by using tetrazine as the linking units, and their performances as anode materials for Li-ion batteries were tested. The results show that TZF exhibits better electrochemical performance than TBFZ owing to the richer active unit tetrazine ring and lower LUMO energy level of TZF. In addition, the specific capacity of TZF is improved in different degrees after cycling at various C-rates. The specific charge capacity increases from 62 to 108.6 mAh·g-1 after 250 cycles at 0.1C, when the charge and discharge rate raises to 1.0C, the capacity increases from 40 up to 139 mAh·g-1 after 1000 cycles, and its coulombic efficiency is always close to 100%, indicating that TZF as an anode material for lithium-ion batteries exhibits good redox activity, good rate performance and cycle stability.
