Abstract Aqueous Sn‐air batteries are attracting a great deal of interest in recent years due to the ultra‐high safety, low cost, dendrite‐free and highly reversible Sn anode. However, slurry oxygen reduction/evolution reaction (ORR/OER) kinetics on air cathodes seriously affect battery performances. Although various advanced catalysts have been developed, charge overpotentials (~1000 mV) these still not satisfactory. Herein, iron oxide (Fe 2 O 3 ) modified titanium dioxide (TiO nanorods with heterogeneous structure firstly synthesized Ti mesh @TiO /Ti), obtained Fe /Ti films further applied as catalytic electrodes for batteries. The core–shell can effectively facilitate conversion electrochemical intermediates separation photo‐excited electrons holes activate oxygen‐related processes. Density functional theory (DFT) experimental results also confirm that only act electrocatalysts improve ORR/OER properties, but exhibit superior photo‐catalytic activity promote charging kinetics. Hence, /Ti‐based show ultra‐low overpotential ~40 mV, excellent rate capability good cycling stability under light irradiation. This work will shed rational photo‐assisted cathode design new‐type metal‐air

Sn metal is a preferable choice as anode material for aqueous acidic batteries due to its acid-tolerance, non-toxicity, and ease of recycling. However, the large size irregular deposition morphology polyhedral particles are bad constructing stable high-capacity because severe hydrogen evolution shedding. To tackle this critical issue, 4-tert-octylphenol pentaethoxylate (POPE) used an electrolyte additive generate thin-film with reversible stripping/plating behavior. POPE can not only induce homogeneous surface chemistry by adsorbing on via coordination bonds but also inhibit modulating solvation shell
