Quasi-solid-state Zn–air batteries typically exhibit limited rate capability (<10 mA cm–2), primarily due to sluggish oxygen electrocatalysis and unstable electrochemical interfaces. Herein, we report a realistic quasi-solid-state battery featuring multiactive sites' MnFeCoNiRu high-entropy alloys uniformly anchored in carbon nanofibers (MnFeCoNiRu/CNF) as the air cathode poly(acrylamide-co-acrylic acid) organohydrogel an antifreezing conductor electrolyte. The proposed exhibits superb bifunctional activity (ΔE = 0.64 V) stability (>10,000 cycles) toward reversible reaction, outperforming commercial Pt/C RuO2, which is mainly MnFeCoNiRu/CNF possessing different active sites reactions, evidenced by situ Raman spectroscopy density functional theory. Furthermore, with its multiple intermolecular hydrogen bond network modified addition of dimethyl sulfoxide reveals strength at freezing temperature (−50 °C) high chemical/mechanical robustness.

Subnanometer materials (SNMs) refer to nanomaterials with a feature size close 1 nm, similar the diameter of single polymer, DNA strand, and cluster/unit cell. The growth assembly subnanometer building blocks can be controlled by interactions at atomic levels, representing limit for precise manipulation materials. size, geometry, flexibility 1D SNMs inorganic backbones are polymer chains, bringing excellent gelability, adhesiveness, processability different from nanocrystals. ultrahigh surface atom ratio results in significantly increased energy, leading significant rearrangement atoms. Unconventional phases, immiscible metal alloys, high entropy few layers stabilized, spontaneous twisting may induce intrinsic structural chirality. Electron delocalization also emerge subnanoscale, giving rise enhanced catalytic activity. In this perspective, we summarized recent progress on SNMs, including their synthesis, polymer-like properties, metastable chirality, toward energy conversion.
