💡 Novelty & Significance:
The work introduces a self-exfoliated bipolar polyimide covalent organic nanosheet anode via an “-NH-” homologation strategy, enabling dual-ion Zn²⁺/SO₄²⁻ storage below 0.6 V. It delivers 185 mAh g⁻¹, 5000-cycle stability, and a record 82.73 Wh kg⁻¹ full cell with MnO₂, offering a dendrite-free, high-performance alternative for aqueous zinc dual-ion batteries.
