Abstract 2D architectures and superior physiochemical properties of MXene offer an exciting opportunity to develop a new class polymer electrolyte membranes by controlling the stacking behavior nanosheets. However, assembling nanosheets into macroscopic stable high‐performance proton conductors is challenging. Here, general strategy reported for achieving MXene‐based heterogeneous via crosslinked cellulose nanofiber/sodium alginate (CNF/SA). Through coordination calcium ions with 1D CNF/SA, abundant hydrogen‐bonding networks are firmly locked network, meanwhile, chains transformed from randomly arranged state long‐range ordered arrangement, such molecular channels collaborate tightly‐stacked jointly guide efficient conduction. Thus, as‐built CNF/SA/MXene (CSM) composite membrane exhibits mechanical (164.7 MPa), conductivity (45.4 mS cm −1 ), power density (49.5 mW −2 low open circuit voltage (OCV) decay rate (0.4 mV h ). The design principle material anchoring through ionic‐cross‐linking mixed‐dimensional assembly can inspire synthesis various ion exchange filtration, transport, sieving, more.

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. A capacity 7.15 Ah energy 110 Wh kgcell–1 are normally measured cycle test under 500 250/500 mAh conditions. operate effectively rates 5–2000 over wide range from −50 60 °C.
