“…Many inorganic materials, including Al 2 O 3 [158,159] , ZnO [113] , amorphous Si [166] , graphite [32,167,168] , LiH 2 PO 4 [169] , BN [161] and Li 3 N [170] , have outstanding reactivity with molten lithium, which can serve as a surface modification layer of garnet SSE to fill the gap between the SSE and lithium electrode. The resulting intimate contact between lithium and garnet SSE leads to a low interfacial resistance decrease.…”

“…A BN nanofilm, which has good insulation and ionic conductivity, was also employed as a protecting layer to reduce the reduction of the SSE by Li metal and stabilize the electrolyte/anode interface [161] . Coating Li 3 N onto the Li metal surface could be an effective method for constructing better SSE-lithium wetted interfaces [170] because Li 3 N has high Li-ion conductivity and is easily prepared by a direct reaction between Li metal and nitrogen at room temperature. Consequently, the surface reactions between the introduced protective interlayers and the Li metal play an essential role in improving the electrode/anode interfacial compatibility and Li-ion and electronic conductivity [171] .…”

All-solid-state lithium-sulfur batteries (ASSLSBs) exhibit huge potential applications in electrical energy storage systems due to their unique advantages, such as low costs, safety and high energy density. However, the issues facing solid-state electrolyte (SSE)/electrode interfaces, including lithium dendrite growth, poor interfacial capability and large interfacial resistance, seriously hinder their commercial development. Furthermore, an insufficient fundamental understanding of the interfacial roles during cycling is also a significant challenge for designing and constructing high-performance ASSLSBs. This article provides an in-depth analysis of the origin and issues of SSE/electrode interfaces, summarizes various strategies for resolving these interfacial issues and highlights advanced analytical characterization techniques to effectively investigate the interfacial properties of these systems. Future possible research directions for developing high-performance ASSLSBs are also suggested. Overall, advanced in-situ characterization techniques, intelligent interfacial engineering and a deeper understanding of the interfacial properties will aid the realization of high-performance ASSLSBs.

“…Lithium-sulfur batteries (LSBs) attract more attention due to their high theoretical capacity of 1675 Ah kg À 1 , high energy density of ~2600 Wh kg À 1 , as well as low cost of sulfur. [1] The severe shuttle effect of lithium polysulfide (LiPS), the slow transformation kinetics of LiPS, and the low conductivity of Li 2 S lead to continuous capacity attenuation, which inevitably limits the development of advanced LSBs. [2] The sulfur cathode host materials can improve the LiÀ S redox kinetics of LSBs.…”

Lithium‐sulfur batteries (LSBs) are considered as the development direction of the new generation energy storage system due to their high energy density and low cost. The slow redox kinetics of sulfur and the shuttle effect of lithium polysulfide (LiPS) are considered to be the main obstacles to the practical application of LSBs. Transition‐metal sulfide as the cathode host can improve the Li‐S redox chemistry. However, there has been no investigation of the application of FeS2 host in Li‐S redox chemistry. Applying the first‐principles calculations, we investigated the formation energy, band gap, Li+ diffusion, adsorption energy, catalytic performance and Li2S decomposition barrier of FeAxS2‐x (A = N, P, O, Se; x = 0, 0.125, 0.25, 0.375) to explore the Li‐S redox chemistry and finally select excellent host material. FeA0.25S1.75 (A = P, Se) has a low Li+ diffusion barrier and superior electronic conductivity. FeO0.25S1.75 is more favorable for LiPS adsorption, followed by FeP0.25S1.75. FeP0.25S1.75(001) shows a low overpotential for the Li‐S redox chemistry. In summary, FeP0.25S1.75 has more application potential in LSBs due to its physical and chemical properties, followed by FeSe0.25S1.75. This work provides theoretical guidance for the design and selection of the sulfur cathode host materials in LSBs.

Nature‐Inspired Strategy: Novel Borohydride‐Based Solid Electrolytes Extracted from Cathode‐Electrolyte Interphase

As the core component of all‐solid‐state batteries, current solid‐state electrolytes fail to simultaneously meet multiple demands, such as their own high performance, the chemical, electrochemical and mechanical compatibility of electrode interface. A fresh perspective is rather desired to guide the development of novel solid electrolytes with comprehensive performance. Herein, this work proposes a novel strategy to synthesize solid electrolytes extracted from cathode‐electrolyte interphase (CEI), which is inspired by peach trees secreting peach gum to prevent further damage. A proof‐of‐concept, using LiBH4‐Se and LiBH4‐S as prototypes, confirms that as‐synthesized electrolytes inherited and improved up the advantages of LiBH4 with unexpected compatibility toward multiple cathodes. It is believed that the family of new electrolytes will be continuously expanded under the guidance of this CEI‐derived concept.
