## Description

- description: "A paucity of redox centers, poor charge transport properties, and
    low structural stability of organic materials obstruct their use in practical
    applications. Herein, these issues have been addressed through the use of a redox-active
    salen-based framework polymer (RSFP) containing multiple redox-active centers
    in \U0001D745-conjugated configuration for applications in lithium-ion batteries
    (LIBs). Based on its unique architecture, RSFP exhibits a superior reversible
    capacity of 671.8 mAh g−1 at 0.05 A g−1 after 168charge-discharge cycles. Importantly,
    the lithiation/de-lithiation performance is enhanced during operation, leading
    to an unprecedented reversible capacity of 946.2 mAh g−1 after 3500 cycles at
    2 A g−1 . The structural evolution of RSFP is studied ex situ using X-ray photoelectron
    spectroscopy, revealing multiple active C═N, C─O, and C═O sites and aromatic sites
    such as benzene rings. Remarkably, the emergence of C═O originated from C─O is
    triggered by an electrochemical process, which is beneficial for improving reversible
    lithiation/delithiation behavior. Furthermore, the respective strong and weak
    binding interactions between redox centers and lithium ions, corresponding to
    theoretical capacities of 670.1 and 938.2 mAh g−1 , have been identified by density
    functional theory calculations manifesting14-electron redox reactions. This work
    sheds new light on routes for the development of redox-active organic materials
    for energy storage applications."
