Arylamine‐Linked Porous Organic Polymers with Abundant Redox‐Active Sites as High‐Capacity and High‐Rate Organic Cathodes for Lithium‐Ion Batteries

. Ex situ FT-IR and XPS spectra combined with theoretical calculations are employed to elucidate the dual-ion storage mechanism. This work provides an effective strategy for designing POPs with high-capacity and high-rate for OCMs.
