Summary: In an intermediate concentration of electrolyte, the electrochemical intercalation of K+ ions in graphite anode exhibits a transition from ternary to binary process. The pre-formed anion-derived solid-electrolyte interphase on the graphite anode remains stable in the intermediate concentration of electrolyte, resulting in a two-year cycle life with a high capacity retention based on binary intercalation.

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: Graphite in potassium-ion batteries shows a faster capacity fade compared to lithium-ion batteries, possibly due to the reactivity of the potassium metal counter electrode or the instability of the solid electrolyte interphase. Previous studies have focused on different electrolyte formulations or charge states of graphite electrodes in potassium half cells. This study compares the surface layers in both charged and discharged states of lithium and potassium half cells, revealing significant differences in SEI composition.

Summary: A stable solid electrolyte interphase (SEI) layer is crucial for high performance lithium ion and lithium metal batteries. Understanding the mechanical properties and behavior of the SEI is essential for rational design, but challenging due to its thin and air-sensitive nature. Various techniques have been used to study the mechanics of SEI, but there is a lack of concise review on the findings so far.

Summary: Multivalent chemistry offers benefits for developing energy storage technologies beyond lithium ion. Metallic zinc anodes are appealing for secondary ion batteries due to their high volumetric capacity at a low cost. However, the complex interfacial mass exchange at the Zn electrolyte/anode boundary and the dynamic progression of the solid electrolyte interphase (SEI) are still not fully understood. Critical differences were observed in SEI formation between nonaqueous and aqueous Zn electrolytes for reversible Zn deposition, with a disproportional loss of coulombs in the nonaqueous electrolyte suggesting in situ formation of an ionically permeable SEI layer.

Summary: The property of solid electrolyte interface (SEI) that is related to the nature of electrolyte directly affects the electrochemical performance of electrode materials in potassium ion battery. The correlation between the potassium storage performance of SnO2@C composite and the generation and properties of SEI film in two different electrolytes was explored in this study. It was found that the superior potassium storage performance of SnO2@C in KFSI-DME electrolyte was due to the thin inorganic-rich SEI film generated mainly from decomposition of KFSI salt, while the thick organic SEI film formed in KPF-ED electrolyte resulted in poor potassium storage performance of SnO2/C as anode material.

Summary: The mechanical stability of the solid electrolyte interphase (SEI) plays a crucial role in achieving exceptional cycling performance of K-metal batteries in low concentration carbonate electrolytes. Higher concentration electrolytes lead to increased inorganic content in SEI, which results in higher Young's modulus and ionic conductivity but lower elastic strain limit. SEI with low mechanical properties can trigger dendrite growth, highlighting the importance of optimizing SEI mechanical stability.

Summary: This study investigates the breathing behavior of solid electrolyte interphases (SEIs) induced by discharging/charging on Fe2O3 conversion-type anodes using cryogenic transmission electron microscopy and spectroscopy. The SEI breathing involves swelling and contracting upon lithiation and de-lithiation due to reversible compositional changes. Bare Fe2O3 anodes develop unstable SEI layers with thickness variation and excessive growth. By applying N-doped carbon coating on Fe2O3, a thinner and chemically more stable SEI layer develops, resulting in significantly enhanced cycling stability.

Li foil with {110} texturing shows superior cycling stability compared to Li {100} or pristine Li foils without specific texturing. The enhanced cycle performance of Li {110} is attributed to its low-surface energy/surface diffusion barrier, resulting in dense Li plating and uniform stripping during cycling.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
