During the last decades, lithium‐ion batteries attracted great attention due to their low cost and environmentally friendly energy storage systems as alternatives for fossil fuels. However, theoretical densities prevent wide utilization human life. Therefore, lithium–sulfur have been introduced high (≈2600 Wh kg −1 ) abundant elements of sulfur cathode. some challenges such shuttle phenomenon, lithium dendritic growth, intrinsic conductivity material inhibit further usage. Thus, many researchers tried solve these issues through deposition processes. According this viewpoint, different chemical physical methods anode, cathode, or separators batteries.

ABSTRACT Lithium‐sulfur batteries (LSBs) are viable options for next‐generation energy storage owing to their nontoxic characteristics, elevated theoretical density, and abundant sulfur. However, LSBs face significant challenges, including the shuttle effect, volumetric expansion, low ionic conductivity, anode degradation. Recent creative developments, such as improved electrolyte compositions, protective coatings, novel interlayers, have been introduced solve these issues. Among these, interlayers suffer from issues with lithium polysulfides (LiPSs) capturing ability, mechanical chemical stability, ion electrical thickness, weight, even though they stand out having potential improve battery performance by managing LiPSs improving electron transport. This study aims develop an innovative interlayer LSB systems synthesizing characterizing a nanohybrid combining high‐surface‐area, high‐ion electrically conductive, mechanically chemically stable three‐dimensional graphene foam (3D GF) ultra‐thin Al 2 O 3 enhancing capture without adding weight or volume. Considering this goal, matrix of nanohybrids was initially developed 3D GF through catalytic vapor deposition (CVD). Following that, amorphous films were deposited on using atomic layer (ALD), cycles varying 25 200, optimize film characteristics. Comprehensive analyses SEM (scanning microscopy), EDX (energy‐dispersive X‐ray spectroscopy), Raman spectroscopy, XRD (X‐ray diffraction), XRR reflectivity) confirmed successful synthesis GF/Al nanohybrids. analysis revealed that porous network structure remained intact following deposition, indicating minimal disruption. demonstrated desired composition thin film, while spectroscopy maintenance structural characteristics postdeposition. showed consistent layer‐by‐layer growth films. Moreover, heat treatment‐focused studies indicated thicker ALD‐based facilitated alpha‐phase crystallization at lower temperatures. To best authors' knowledge, introduces initial design producing nanohybrids, revealing approach towards straightforward, effective, scalable production methods alternative effective strategy.

Abstract Although Li metal is considered the most promising anode material owing to its high theoretical capacity, there are numerous restrictions on expanding application because of undesired surface reactions occurring at anode. To solve this, an effective electrolyte combination consisting 1,1‐diethoxyethane (DEE) and lithium bis(fluorosulfonyl)imide (LiFSI) used in this work, which can provide organic/inorganic‐hybridized solid‐electrolyte interphase (SEI) The DEE solvent affords flexible carbon‐abundant components, whereas LiFSI offers mechanically rigid fluoride‐type components; these undergo electrochemical reduction form SEI layers that balanced terms organic inorganic components. Systematic analysis results exhibit when layer integrated with embedded anode, decomposition, dendritic growth suppressed Li/Li cells, thereby improving stability. Similarly, it provides stable cycle life characteristics even 150 cycles Li/S cells (72.0% vs 52.6%).
