💡 Novelty & Significance:
The novelty lies in an in situ polymerized gel electrolyte using AMPSNa, whose anchored anions dual-regulate Na⁺ desolvation and form a stable, ion-conductive SEI. This enables enhanced anode kinetics and interfacial stability in sodium-ion capacitors, achieving 171.2 Wh kg⁻¹ and 96.1% retention over 10,000 cycles—offering a viable route to high-performance, leak-free SICs.
