Hybrid based on Phenazine Conjugated Microporous Polymer as a High‐Performance Organic Electrode in Aqueous Electrolytes

Incorporating redox active units in a 3D porous network is an encouraging strategy to enhance electrochemical performance of organic electrode materials. Herein, new hybrid composed by phenazine-based conjugated microporous polymer (IEP-27-SR, stand for IMDEA Energy Polymer number 27) and single-walled carbon nanotubes (SWCNTs) graphene oxide (RGO) synthesized, fully characterized tested electrochemically different aqueous electrolyte conditions, i. e., at various pH values (1–12) also with charge carriers (H+ acidic, Li+, Na+, K+ neutral alkaline electrolytes). Although the IEP-27-SR found be very versatile showing good electrochemistry both acidic solution, it exhibits best specific capacity, kinetics cycle stability electrolyte. Then encouragingly, when combined activated (AC) counter construct proof-of-the-concept device, IEP-27-SR//AC demonstrates high capacity (168 mAh g−1 2 C), impressive rate (96 60 C) ultra-long (76 % retention over 28800 cycles 10 C; 2690 h) 1 M H2SO4.
