Summary: This study investigates the impact of electrolyte chemistry on the dissolution of the solid electrolyte interphase (SEI) in sodium-ion batteries, using beta-alumina as a sodium-conductive membrane to prevent crosstalk. The research found that the solubility of SEI species in the electrolyte can reach up to 30% after a 50-hour pause, and saturation of the electrolyte with these SEI species can counteract aging due to SEI dissolution.

Summary: In this study, the interface stability of sodium ion batteries (SIBs) is improved by suppressing the continuous growth of the solid-electrolyte interphase (SEI) from the perspective of mitigating electron leakage. Two types of SEI layers with different growth behaviors were created through the additive strategy, and their physicochemical features and electronic properties were extensively investigated. Experimental and calculational analyses demonstrated that the suppressed growth SEI layer exhibits both low electron driving force and high electron insulation ability, mitigating electron leakage and enhancing electrochemical performance.

Summary: In this study, correlative scanning electrochemical cell microscopy (SECCM) and shell-isolated nanoparticles for enhanced Raman spectroscopy (SHINERS) were used to screen the formation of solid-electrolyte interphase (SEI) on Si electrodes. The results revealed the heterogeneous and dynamic nature of SEI, showing characteristic evolution as a function of cycle number. This correlative technique has the potential to accelerate the optimization of SEI formation methods in lithium-ion batteries.

Summary: A composite lithium anode (CLA) was designed and prepared to solve the obstacles of huge interfacial resistance and growth of detrimental Li dendrites in solid-state lithium metal batteries (SSLMBs). The CLA significantly improved the intrinsic ionic diffusion capability of the lithium anode and simultaneously enhanced the wettability of the anode towards solid-state electrolyte, resulting in a robust and high ionic conductive solid-state interface. The SSLMB with the CLA achieved excellent cycling performance and high-rate capability, demonstrating its potential for high-performance solid-state Li metal batteries.

Summary: Beta-naphthol reds are widely used pigments with significant historical, commercial, and cultural importance. This research focuses on the structural characterization of two prominent beta-naphthol reds, pigment red 40 (PR40) and pigment red 4 (PR4). The study confirms that both pigments exist as keto/hydrazones in the solid state, and suggests that they should not be mistakenly labeled as azo pigments. The research also investigates the lightfastness of the pigments, finding that while they remain stable in the solid state, degradation occurs when exposed to UV radiation in solution.

Summary: In this study, a novel lithium-sulfur cell configuration was achieved by using a polysulfide cathode and a sulfide solid electrolyte. The liquid-solid interface provided by the polysulfide catholyte enhanced charge transfer and lithium-ion diffusion. The formation of lithium phosphide and lithium phosphate created an ionically conductive protection layer, optimizing the contact between the polysulfide cathode and the solid electrolyte and stabilizing the active electrodes.

Summary: The problems of zinc anode, such as dendrite growth and hydrogen evolution, significantly impair the performance of zinc batteries. The solid electrolyte interphase (SEI), crucial for achieving high reversibility of lithium anode in non-aqueous organic solvents, also contributes to the improvement of zinc anode performance in aqueous electrolytes. However, current research on the interphase for zinc electrodes is fragmented, lacking a deep understanding of the underlying causes or general design rules for SEI construction. The high reactivity of water molecules poses a serious challenge for effective SEI formation.

Summary: The study explored a series of amphiphilic indoline-based unsymmetrical squaraine dyes, where alkyl groups and glycolic chain were systematically modified to control self-assembly and improve interfacial properties. In nonaqueous DSSCs, increasing the number of carbon atoms in alkyl groups enhanced photovoltaic efficiencies. Addition of chenodeoxycholic acid improved efficiency, while increased carbon atoms in the alkyl groups had a detrimental effect on aqueous DSSC efficiency.

Summary: Aqueous zinc metal batteries (AZMBs) are a promising electrochemical energy storage technology due to their high safety, low cost, and high energy density. However, they suffer from side reactions such as dendrite formation and hydrogen evolution. Researchers at the University of Adelaide have developed a novel electrolyte using dimethyl methylphosphonate (DMMP) as a solvent to create a stable and uniform phosphate-based solid electrolyte interface (SEI) layer on the zinc surface. This results in improved Coulombic efficiencies and capacity retentions.

Summary: The mechanism of SEI formation and evolution on Si-based electrodes with and without binder induced by lithiation and delithiation has been elucidated using Si@C-network and Si-XG-AB electrodes. The results demonstrate that the SEI layer on Si-XG-AB electrode partially decomposes during the charging process, leading to a less stable layer, while the SEI layer on Si@C-network electrode shows better stability with less decomposition.

Summary: This study focuses on investigating the sodiation mechanism of non-graphitizing carbons (NGC), and reveals that increasing the pyrolysis temperature leads to NGCs with a more ordered structure and developed closed microporosity. In situ Raman spectroscopy shows that the intercalation of Na+ between the graphene layers occurs mainly during the sloping part of the galvanostatic profile, while the plateau at low voltage can be associated with the filling of micropores with sodium.
