An indole-based conjugated microporous polymer: a new and stable lithium storage anode with high capacity and long life induced by cation–π interactions and a N-rich aromatic structure

An indole-based conjugated microporous polymer, poly(bisindolylmaleimide) (PBIM), with superior electrochemical performance as an anode material for LIBs has been obtained by FeCl 3 -promoted oxidative coupling polymerization. Benefiting from reversible cation–π interactions and a unique aromatic st...

description An indole-based conjugated microporous polymer, poly(bisindolylmaleimide) (PBIM), with superior electrochemical performance as an anode material for LIBs has been obtained by FeCl 3 -promoted oxidative coupling polymerization. Benefiting from reversible cation–π interactions and a unique aromatic structure containing N heteroatoms, the prepared PBIM anode shows high capacity (1172 mA h g −1 , 50 mA g −1 ), outstanding cycle life (1000 cycles), and remarkable rate performance (214 mA h g −1 , 2.5C).
