Abstract

Lithium ion batteries possessing the ability of fast charging without compromising on the reversible capacity are the need of the hour. To this end, there is a need to develop active materials that support this property. Owing to the benefits of structural tunability and the possibility of including various Herero atoms in the structure, organic polymers offer a promising candidacy as anodic active materials. In this study, synthesis of BIAN-Bismarck brown based azo and imine functional porous organic polymer and its application as high capacity anode, delivering 500 mAh/g at 0.4 A/g was presented. Besides, the application as a high capacity anode, BBP was also used as a precursor to derive N-doped carbon labelled as PyBBP600 (pyrolysed at 600) and PyBBP800 (pyrolysed at 800). PyBBP800 delivered excellent rate capability and long cyclability at 4 A/g, delivering 125 mAh/g for 5000 cycles. Thereby the application of organic polymer for high energy and high power applications is presented in this work.
