Benefiting from the merits of intrinsic safety, high power density, environmental friendliness, and high‐output voltage, aqueous dual‐ion batteries (ADIBs) have shown broad potential applications in future grid‐scale energy storage. However, since the ADIBs require the cathodes to undergo the intercalation reactions through different local structures and mechanisms, causing large structural deformation and cathode failure, their reversible cation‐anion intercalation in the cathode remains a major challenge. To address this issue, based on a reasonable selection and theoretical simulation, this work finds that Todorokite manganese dioxide (t‐MnO2) cathode with a metal‐ion stabilized 3 × 3 large‐tunnel structure should be suitable for cation‐anion intercalation of ADIBs. The comprehensive characterizations confirm that the unique tunnel structure of the t‐MnO2 cathode can withstand large structural deformation during the sulfate radical anion– zinc/proton cation (SO42−–Zn2+/H+) intercalation. Due to the intercalation of SO42−, the ADIB delivered a high reversible capacity of 398 mAh g−1 at 0.2 A g−1 with an output voltage of ≈1.41 V, which is much higher than the theoretical capacity (308 mAh g−1) of Zn‐MnO2 based Zinc‐ion batteries. This work provides the design principles for ADIBs cathode materials and demonstrates that t‐MnO2 can be a promising cathode material for high‐performance ADIBs.

Efficient water electrolysis for green hydrogen production relies on the development of robust oxygen evolution reaction (OER) catalysts, particularly for acidic environments. This study introduces amorphous/crystalline Mn‐Ru binary oxides nanoflowers (a/c‐Mn0.9Ru0.1O2) as a promising acidic OER catalyst, synthesized via a two‐step phase engineering approach. The optimized a/c‐ Mn0.9Ru0.1O2‐200 composition exhibits exceptional OER activity, requiring a low overpotential of 168 mV to achieve a current density of 10 mA/cm2 and demonstrating remarkable stability over 28 hours. This significantly outperforms commercial RuO2 catalysts, which require an overpotential of 320 mV at 10 mA/cm2 and exhibit a stability of only 0.5 h under identical conditions. X‐ray absorption spectroscopy (XAS) and X‐ray photoelectron spectroscopy (XPS) analysis results reveals the formation of Mn‐O‐Ru linkages and an optimized d‐band electronic structure, attributed to strong electronic coupling at the amorphous/crystalline interface. This unique architecture promotes optimal adsorption/desorption of OER intermediates, leading to enhanced catalytic performance. This study offers a novel strategy for the rational design and production of efficient acidic OER catalysts.
