“…The high‐resolution XPS spectrum of Sn 3d for Sn@Cu foam electrodes showed the presence of two valence states of Sn (Figure 4D‐F): Sn metal at 485.0 eV and SnO 2 at 486.9 eV. The Sn 3d 5/2 and Sn 3d 3/2 peaks for both metal and oxide were separated by 8.4 eV 41,42 . Sn@Cu foam electrodes were fabricated and stored in an open atmosphere, thus the presence of SnO 2 may arise from atmospheric oxidation.…”

“…The Sn 3d 5/2 and Sn 3d 3/2 peaks for both metal and oxide were separated by 8.4 eV. 41,42 Sn@Cu foam electrodes were fabricated and stored in an open atmosphere, thus the presence of SnO 2 may arise from atmospheric oxidation. The peaks of metallic Sn were significantly higher for Sn@Cu foam (Na 2 SnO 3 ) electrode than others; thus, the metallic Sn stably exists on the surface of Cu foam electrode, which was beneficial to reduce hydrogen evolution overpotential and side reactions.…”

Summary Aqueous zinc batteries (AZBs) hold great promise for advancing applications in next‐generation energy storage devices because of their high safety, high energy density, and low cost. However, zinc metal anodes have greatly impeded the application in AZBs due to their poor cycle performance. Short lifespan, which is caused by dendritic growth, deformation, corrosion, and competing hydrogen evolution, is very tricky. Herein, a stable Sn@Cu foam, prepared by plating tin on copper foam, is reported as the substrate of Zn anodes. We evaluate the quality of plating tin layers, which are prepared by using different tin salt solutions, and Na2SnO3 solution is eventually selected. Electrochemical tests show that Sn@Cu foam can not only inherit the merits of Cu foam but also suppress hydrogen evolution reaction and lower the initial heterogeneous nucleation barrier of deposited Zn. Moreover, in situ observation by optical microscope demonstrates that Zn dendrite growth on Sn layer is suppressed during the plating‐stripping process. As a result, a compact Zn layer on Sn@Cu foam is obtained (Zn/Sn@Cu foam), symmetrical cells display superior cycling life of 1800 h at 1 mA cm−2 for 1 mAh cm−2, and full cells with VO2 cathode deliver remarkably better cycling stability and longer lifespan.

“…The surface morphology of cathode unit is a performance decisive factor in TEOLEDs. Unlike Mg:Ag thin film that codeposited with Mg and Ag, thin pristine Ag film is known to form a stable morphology due to its high surface energy [27]. Indeed, this is the critical issue when thin pristine Ag film is applied in TEOLED devices.…”

We report, highly efficient red top emission organic light emitting diodes (TEOLEDs) having thin pristine Ag cathode unit with low absorption, uniform surface morphology and good electron injection property. TEOLEDs with Ag cathode unit exhibit almost 1.4 times improvement in current efficiency as well as low driving voltage compared with widely used Mg:Ag cathode and almost identical lifetime with Mg:Ag cathode.
