dc.description.abstract | The rational design of wide-temperature operating Zn-air batteries is crucial for their practical applications. However, the fundamental challenges remain; the limitation of the sluggish oxygen redox kinetics, insufficient active sites, and poor efficiency/cycle lifespan. Here we present heterointerface-promoted sulfur-deficient cobalt-tin-sulfur (CoS1-delta/SnS2-delta) trifunctional electrocatalysts by a facile solvothermal solution-phase approach. The CoS1-delta/SnS2-delta displays superb trifunctional activities, precisely a record-level oxygen bifunctional activity of 0.57 V (E-1/2 = 0.90 V and E-j=10 = 1.47 V) and a hydrogen evolution overpotential (41 mV), outperforming those of Pt/C and RuO2. Theoretical calculations reveal the modulation of the electronic structures and d-band centers that endorse fast electron/proton transport for the hetero-interface and avoid the strong adsorption of intermediate species. The alkaline Zn-air batteries with CoS1-delta/SnS2-delta manifest record-high power density of 249 mW cm(-2) and long-cycle life for >1000 cycles under harsh operations of 20 mA cm(-2), surpassing those of Pt/C + RuO2 and previous state-of-the-art catalysts. Furthermore, the solid-state flexible Zn-air battery also displays remarkable performance with an energy density of 1077 Wh kg(-1), >690 cycles for 50 mA cm(-2), and a wide operating temperature from +80 to -40 degrees C with 85% capacity retention, which provides insights for practical Zn-air batteries. | - |
