Abstract

An indole-based conjugated microporous polymer, poly(bisindolylmaleimide) (PBIM), with superior electrochemical performance as an anode material for LIBs has been obtained by FeCl3-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).
