| 摘要 | Microporous organic polymers with triphenylamine segments were employed as cathode materials for lithium ion batteries. YPTPA with the highest surface area exhibits a discharge plateau at similar to 3.6 V vs. Li/Li+, an initial Coulombic efficiency of 96.8% at 50 mA g(-1) and a discharge capacity of 105.7 mAh g(-1) at 200 mA g(-1). Compared to the homo-coupled polymer of OPTPA with relatively low surface area (66 m(2) g(-1)), SPTPA and YPTPA with higher surface area (544 and 1557 m(2) g(-1), respectively) show enhanced rate performances and energy densities. YPTPA can deliver 97.6 mAh g(-1) within less than 3 min at high rate of 2000 mA g(-1) and the energy density of 334 Wh kg(-1) under an ultrahigh power density of 6816 W kg(-1), while OPTPA only presents 48.2 mAh g(-1) at 2000 mA g(-1) with an energy density of 155 Wh kg(-1) under 6414 W kg(-1). The great improvement in electrochemical properties of SPTPA and YPTPA demonstrates that increasing surface area of polymer cathodes by interweaving the redox-active units into microporous polymer skeleton is an efficient way to develop advanced polymer cathode materials with outstanding electrochemical performance.
