Inducing the classic strong metal-support interaction (SMSI) is an effective approach to enhance the performance of supported metal catalysts by encapsulating the metal nanoparticles (NPs) with supports. Conventional thermal reduction method for inducing SMSI processes is often accompanied by undesirable structural evolution of metal NPs. In this study, a mild electrochemical method has been developed as a new approach to induce SMSI, using the cable structured core@shell CNT@SnO₂ loaded Pt NPs as a proof of concept. The induced SnO_x encapsulation layer on the surface of Pt NPs can protect Pt NPs from the poisoned of CO impurity in hydrogen oxidation reaction (HOR), and the HOR current density could still maintain 85% for 2000 s with 10000 ppm CO in H₂, while the commercial Pt/C is completely inactivated. In addition, the electrons transfer from SnO_x to Pt NPs improved the HOR activity of the E-Pt-CNT@SnO₂, achieving the excellent exchange current density of 1.55 A·mg_Pt^-1. In situ Raman spectra and theoretical calculations show that the key to the electrochemical-method-induced SMSI is the formation of defects and the migration of SnO_x caused by the electrochemical redox operation, and the weakening the Sn-O bond strength by Pt NPs.

All-solid-state lithium-ion batteries (LIBs) using ceramic electrolytes are considered the ideal form of rechargeable batteries due to their high energy density and safety. However, in the pursuit of all-solid-state LIBs, the issue of lithium resource availability is selectively overlooked. Considering that the amount of lithium required for all-solid-state LIBs is not sustainable with current lithium resources, another system that also offers the dual advantages of high energy density and safety— all-solid-state sodium-ion batteries (SIBs) —holds significant sustainable advantages and is likely to be the strong contender in the competition for developing next-generation high-energy-density batteries. This article briefly introduces the research status of all-solid-state SIBs, explains the sources of their advantages, and discusses potential approaches to the development of solid sodium-ion conductors, aiming to spark the interest of researchers and attract more attention to the field of all-solid-state SIBs.

Continued growth in energy demand and increased environmental pollution constitute major challenges that need to be addressed urgently. The development and utilization of renewable, sustainable, and clean energy sources, such as wind and solar, are crucial. However, the instability of these intermittent energy sources makes the need for energy storage systems increasingly urgent. Aqueous zinc-ion batteries (AZIBs) have received widespread attention due to their unique advantages, such as high energy density, cost-effectiveness, environmental friendliness, and safety. However, AZIBs face significant challenges, mainly the formation of zinc dendrites that seriously affect the stability and lifetime of the batteries, leading to battery failure. Therefore, reducing the formation of zinc dendrites is crucial for improving the performance of AZIBs. This review systematically and comprehensively comprehends the current strategies and advances in inhibiting the formation of zinc dendrites. By comprehensively analyzing the latest developments in zinc anode, electrolyte, separator design and modification, as well as other novel mechanisms, it provides researchers with a thorough understanding to guide future research and advance the development of AZIBs.
