💡 Novelty & Significance:
γ-ray irradiation enables reagent-free, dose-controlled engineering of 3D PVA binder networks for Li─S cathodes. The 3 kGy dose yields optimal topology, coupling mechanical integrity with ionic/electronic transport, achieving 0.045% decay per cycle over 1000 cycles and 390.2 Wh kg⁻¹ in a 1.23 Ah pouch cell. This establishes a clean, catalyst-free strategy linking binder topology to electrode mechanics and electrochemistry.
