POP based nitrogen containing anodic materials for high capacity and fast Charge-Discharge applications in LIB

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.
