Summary: The formation of lithiophobic inorganic solid electrolyte interphase (SEI) on Li anode and cathode electrolyte interphase (CEI) on the cathode is beneficial for high-voltage Li metal batteries. However, decomposition of organic solvents in most liquid electrolytes leads to the formation of organic components in the SEI and CEI. This poses safety risks due to their high volatility and flammability. An organic-solvent-free eutectic electrolyte based on low-melting alkali perfluorinated-sulfonimide salts is reported, which shows promising results for ultrasafe and high-energy Li metal batteries.

Summary: Rechargeable magnesium batteries (RMBs) are promising for their potential in high energy density, low cost, and high safety. However, technological breakthroughs are required for commercialization. Cathode materials are crucial for the commercialization of RMBs as they directly affect energy and power densities. The main challenge lies in the poor diffusion of Mg2+ ions in electrode materials due to strong interaction with host materials. Various attempts have been made to overcome this issue, including synthesis of new materials, morphological modifications, doping, substitution, and addition of second components. This review provides additional information on recent developments in cathode materials for RMBs in the past 3-4 years, as well as perspectives and challenges for future development.

Summary: Facile and efficient production of ultra-stable metal nanocatalysts based on strong metal-support interactions (SMSI) was achieved through ultrasonication in water at ambient conditions, which generated abundant active intermediates, Ti3+ ions, and oxygen vacancies to induce SMSI overlayer formation. The degree of encapsulation could be controlled by the reducibility of solvents and ultrasonication parameters. This approach can be extended to other metal oxide supports and noble metal nanoparticles, leading to enhanced performance in hydrogenation reactions and CO2 conversion.

Summary: In this study, we combine computational chemical reaction network (CRN) analysis based on density functional theory (DFT) and differential electrochemical mass spectroscopy (DEMS) to study gas evolution from a model Mg-ion battery electrolyte. The results reveal H(2)O, C2H4, and CH3OH as major decomposition products, which are explained by identifying elementary reaction mechanisms using DFT. This combined theoretical-experimental approach provides a means to effectively predict electrolyte decomposition products and pathways when initially unknown.

Summary: High-capacity cathodes (LiNi0.8Mn0.1Co0.1O2, NMC811) have the potential for vehicle electrification due to their high gravimetric energy density, but their electrochemical performance depends on the stability of the cathode electrolyte interphase (CEI). A conformal LiF layer formed on the NMC811 electrode surface through an in situ ion-exchange metathesis process improves the electrochemical performance by stabilizing the CEI. This finding could pave the way for enhancing the electrochemical performances and cycling stability of high-capacity cathodes by reengineering the CEI.

Summary: Developing a powerful bifunctional catalyst is crucial for achieving future carbon neutrality by reducing energy consumption in the chemical industry. This study synthesizes mesoporous zeolite-encapsulated palladium nanoparticles (Pd@meso-ZSM-5) using emulsification-demulsification and dry-gel transformation methods, which exhibit remarkable catalytic performance in the one-pot multiple tandem reaction of cyclic ketones to bicyclic alkanes. Unlike traditional two-step synthesis routes, Pd@meso-ZSM-5 efficiently produces bicyclic alkanes instead of monocyclic alkanes, due to the sufficient space for large molecular intermediates provided by mesoporosity and the promoting effect of the acid-Pd interface on intermediate conversion.

Summary: The methylation of imidazolium-based room temperature ionic liquids (RTILs) paired with [Tf2N](-) anion results in an unexpected increase in viscosity, while the viscosity decreases when the methylated imidazolium is paired with [B(CN)(4)](-) anion. The compensated Arrhenius formalism (CAF) is used to study the viscosity observations, focusing on the activation energy and entropy of activation. The results show that the activation energy increases with methylation for [Tf2N](-), but decreases for [B(CN)(4)](-).
