Abstract
© 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. The synthesis of a new type of redox-active covalent triazine framework (rCTF) material, which is promising as an anode for Li-ion batteries, is reported. After activation, it has a capacity up to ≈1190 mAh g−1 at 0.5C with a current density of 300 mA g−1 and a high cycling stability of over 1000 discharge/charge cycles with a stable Coulombic efficiency in an rCTF/Li half-cell. This rCTF has a high rate performance, and at a charging rate of 20C with a current density of 12 A g−1 and it functions well for over 1000 discharge/charge cycles with a reversible capacity of over 500 mAh g−1. By electrochemical analysis and theoretical calculations, it is found that its lithium-storage mechanism involves multi-electron redox-reactions at anthraquinone, triazine, and benzene rings by the accommodation of Li. The structural features and progressively increased structural disorder of the rCTF increase the kinetics of infiltration and significantly shortens the activation period, yielding fast-charging Li-ion half and full cells even at a high capacity loading
