Summary: Argyrodite-type Li6PS5Cl (LPSCl) has attracted attention as a solid electrolyte for all-solid-state batteries due to its high ionic conductivity and mechanical flexibility. However, the interface between LPSCl and cathode materials faces challenges such as electrochemical degradation. In this study, trimethylsilyl compounds were introduced as solid electrolyte additives to improve the interfacial stability between sulfide-based solid electrolytes and cathode materials, resulting in excellent electrochemical performance and enhanced cycle life.

Summary: Na4P2S7-6xO4.62xN0.92x (NaPSON) glassy solid electrolytes (GSEs) were studied for their electrochemical properties and processability into thin films. The x = 0.2 composition (NaPSON-2) showed high conductivity, non-crystallizability, stability against Na-metal, and support for symmetric cell cycling. Thin films of NaPSON-2 exhibited unchanged conductivity and slow growth in resistance, while NaPSON-2 disc displayed stability and reaction products in the bulk. The surface stability was attributed to the segregation of trigonally coordinated nitrogen.

Summary: Sulfide solid electrolyte (SE) and silicon anodes play important roles in all-solid-state batteries (ASSBs), but the bulk instability of sulfide SE and poor utilization of silicon materials pose significant challenges. Improving strategies for sulfide SEs and factors affecting silicon-sulfide SE compatibility, such as carbon's effect and particle size of silicon, need to be considered.

Summary: This study demonstrates the use of an ionic liquid interlayer to address interfacial issues in sulfide-based solid-state sodium batteries (SSSBs). The interlayer stabilizes the Na metal/SSE interface, enabling the formation of a stable solid electrolyte interphase (SEI) and preventing harmful reactions and Na dendrite growth. Experimental and simulation results reveal that the stable SEI is composed of reduced products of TFSI-. Symmetric cells and FeS2||Na quasi-solid-state batteries exhibit stable cycling performance and high specific capacity.

Summary: In this study, a novel cyclic siloxane additive, TMDSi, was proposed to improve the capacity retention and suppress the dissolution of transition metal ions of Ni-rich cathode materials during long-term cycling. The working mechanism of TMDSi was revealed through various techniques, and it was found that TMDSi can effectively scavenge HF and form a protective film on the cathode surface to maintain its morphology and reduce parasitic side reactions. This bifunctional working mechanism makes TMDSi a promising electrolyte additive for Ni-rich cathode in Li-ion batteries.

Summary: The rock-salt phase (RSP) formed on the surface of Ni-rich layered cathodes in liquid-electrolyte lithium-ion batteries is considered electrochemically inactive. However, in sulfide based all solid state batteries (ASSBs), massive RSP forms in the interior of LiNixMnyCo(1_x-y)O2 (NMC) crystals and remains electrochemically active even after long cycles. The tensioned layered phase in ASSBs allows lithium to be squeezed out of RSPs by compressive stress, rendering the RSPs electrochemically active. This discovery enables the development of high energy density and durable ASSBs.

Summary: In chemistry, the theory of aromaticity or pi bond resonance is crucial for understanding the stability and properties of organic molecules. This study presents an analogue theory for sigma bond resonance in flat boron materials, allowing for the determination of two-center two-electron and three-center two-electron bond distributions without quantum calculations. Based on this theory, three rules are proposed for drawing Kekule-like bonding configurations and exploring properties of flat boron materials. Additionally, the theory is applied to explain the stability of neutral borophene with approximately 1/9 hole occupancy and the effect of charge doping on borophene's optimal hole concentration. This theory enhances our understanding of boron materials and facilitates the rational design of boron-based materials.

Summary: Recently, all-solid-state lithium-ion batteries (ASSLBs) have gained significant attention, but degradation processes at the composite cathode interface, including side electrochemical reactions and morphological/structural degradation, still hinder their development. In this study, an elastic and sticky interfacial layer was successfully assembled for ASSLBs using molecular layer deposition (MLD) technique. This layer not only suppressed side reactions but also enabled close contact between NCM811 particles and the electrolyte. The results showed improved capacity retention and lower irreversible resistance compared to bare NCM811. This work highlights the importance of elastic and sticky coatings in maintaining the electrochemical-mechanical integrity of composite cathode materials for ASSLBs.
