Abstract Aqueous hydrogen gas batteries (AHGBs) are demonstrated to possess ultra‐long lifetimes and high reliability, making them highly promising for large‐scale energy storage applications. Consequently, the development of high‐efficiency, low‐cost, scalable oxidation/reduction (HOR/HER) catalytic electrode materials is essential promoting industrialization AHGBs. In this study, a processible platinum‐ruthenium‐nickel multimetallic aerogel catalyst presented with pH‐universal HOR/HER activity synthesized by facile method, exhibiting potential industrial‐grade production. Theoretical calculations reveal that synergistic adsorption on different metal atoms optimizes reaction path, thus enhancing activity. Fabricated an extremely low loading (≈30 µg PtRu cm −2 ), both alkaline nickel‐hydrogen (Ni‐H 2 ) battery acidic manganese‐hydrogen (Mn‐H demonstrate performance exceeding 2500 h at 0.5 C over 1500 cycles 20 C, respectively, significantly surpassing those commercial Pt/C catalyst. Notably, 5 Ah scaled‐capacity Ni‐H assembled exhibits exceptional density 169 Wh kg −1 cost US$ 74 kWh based all components cell, providing possibilities commercialization AHGBs in applications future.

Abstract Integrated electrochemical energy devices with multifunctionality are evolving as an auspicious way to lift up technology. However, the challenge is utilizing a single‐electrode material for multifunctional applications essential minimize manpower and overall cost of system. Herein, novel cost‐effective self‐powered aqueous device (SAEED) proposed via integrating asymmetric supercapattery (ASD) water‐splitting (WS) Cu₃Mo₂O₉ (CMD) nanostructures on Ni‐foam (prepared hydrothermal method) trifunctional electrode. First, Cu 3 Mo 2 O 9 /Ni electrode examined supercapacitor, which shows faradaic‐type charge‐storage behavior superior specific capacity 588.88 mAh g −1 . The ǁgraphene ASD constructed, high storage performance capacitance energy/power densities 98% retention over 5000 cycles. Second, electrocatalyst Cu₃Mo₂O₉/Ni explored, reveals impressive HER/OER lower overpotential (HER‐120 mV at 10 mA cm⁻²/OER‐310 50 cm⁻²) values. As proof‐of‐concept, SAEED was developed that contains thermoelectric generator, Cu₃Mo₂O₉ǁgraphene ASD, beaker‐type electrolyzer operating voltage 1.58 V eliminate power loss intermittent issues sustainable uninterrupted production H₂.
