摘要:: 共軛微孔聚合物因其交聯(lián)多孔的骨架及高度共軛的結(jié)構(gòu)，在鋰離子電池電極材料領(lǐng)域具有巨大的應(yīng)用前景。以四嗪作為連接單元，構(gòu)筑了具有氧化還原活性的共軛微孔聚合物TZF和TBFZ，并對(duì)該共軛微孔聚合物作為鋰離子電池負(fù)極材料的性能進(jìn)行了測(cè)試。結(jié)果表明，由于具有更豐富的活性單元四嗪環(huán)以及更低的最低未占分子軌道能級(jí)，TZF展現(xiàn)出比TBFZ更好的電化學(xué)性能。此外，在不同的電流密度下循環(huán)后，TZF比容量均有不同程度的提高。當(dāng)電流密度為0.1C時(shí)，循環(huán)250次后比充電容量從62增加到108.6 mAh·g-1；電流密度為1.0C時(shí)，循環(huán)1000次后比充電容量從40提高到139 mAh·g-1，并且?guī)靷愋适冀K接近100%，表明TZF作為鋰離子電池負(fù)極材料具有良好的氧化還原活性及循環(huán)穩(wěn)定性。

Abstract:: 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.
