Heptazine-Based Polyimide with Dense Redox Sites and Large Conjugated Structure for Cathodic Lithium-Ion Storage

As organic cathode materials for lithium-ion batteries (LIBs), polyimides (PIs) have attracted widespread attention due to their abundant redox-active carbonyl sites, structural tunability, and environmental compatibility. However, the presence of electrochemically inactive structural units in conventional PIs limits...
