Abstract Compared with Zn 2+ , the current mainly reported charge carrier for zinc hybrid capacitors, small-hydrated-sized and light-weight NH 4 + is expected as a better one to mediate cathodic interfacial electrochemical behaviors, yet has not been unraveled.

Silicon (Si) and Si-based compounds have been considered by many researchers as one of the anode materials for next-generation lithium-ion batteries (LIBs) due to their extraordinarily large theoretical capacity, moderate operating voltage, abundant resources. However, silicon's poor conductivity significant volume changes during charge discharge, compared conventional carbon materials, severely restrict its widespread use in LIBs. In this study, a two-dimensional (2D) mesoporous Si nanosheet/carbon (pSi@C) composite is designed using cetrimonium bromide–disodium edetate dihydrate (CTAB–EDTA) template via sol–gel method, magnesium thermal reduction decomposition method. The vertical diffusion distance Li+ significantly reduced 2D nanosheets. Additionally, coating on surface provides protective layer limit expansion form stable solid electrolyte interface (SEI). This enhances structural integrity cycle stability pSi@C material insertion extraction.

Therefore, unique technology can be used design composites excellent properties, thereby providing an effective strategy commercial application

Abstract Beyond the high theoretical capacity, conversion‐alloying metal chalcogenides (CAMCs) exhibit exceptional high‐rate performance as Li‐ion battery electrodes. However, inherent origin of remains elusive, especially given lower intrinsic conductivity CAMCs. Here, correlation between phase evolution and charge transport dynamics in fully activated CAMCs is systematically investigated, elucidating a current‐adaptive storage mechanism to explain anomalous performance. Briefly, deconversion reaction manipulated by ion diffusion acts “regulator” adaptively modulate transition from (high electronic conductivity) lithium ionic CAMCs, thus removing bottleneck without affecting formation feedstock required for alloying reaction. On this basis, capacity can be maintained at rates through “fading‐free” This study offers novel perspective design electrode materials.

Abstract Zinc metal is a promising anode candidate for aqueous zinc ion batteries due to its high theoretical capacity, low cost, and safety. However, application currently restricted by hydrogen evolution reactions (HER), by‐product formation, Zn dendrite growth. Herein, “Zn 2+ in salt” (ZIS) interphase situ constructed on the surface of (ZIS@Zn). Unlike conventional water” working environment anodes, intrinsic hydrophobicity ZIS isolates from direct contact with electrolyte, thereby protecting it HER, accompanying side reactions. More importantly, works as an ordered water‐free ion‐conducting medium, which guides uniform deposition facilitates rapid migration at interface. As result, symmetric cells assembled ZIS@Zn exhibit dendrite‐free plating/striping 4500 h critical current 14 mA cm −2 . When matched vanadium‐based (NVO) cathode, full battery exhibits excellent long‐term cycling stability, 88% capacity retention after 1600 cycles. This work provides effective strategy promote stability reversibility anodes electrolytes.
