Developing solid-state electrolytes (SSEs) is a critical task for advancing all-solid-state batteries (ASSBs) that promise high energy density and improved safety. The dominant strategy in engineering advanced SSEs has been substitutional doping, where foreign atoms are introduced into the atomic lattice of host material to enhance ionic conduction. This enhancement typically attributed optimized charge carriers' concentration or structure alterations. In this study, we extend concept doping explore its effects on chemical bond modulation resulting impact conduction halide SSEs. As case demonstrate cation dopants with indices (e.g., Al3+ Fe3+) can increase covalency metal–halide (M–X) bonds induce local asymmetric field force, higher site lower migration barriers, which significantly frameworks. Specifically, developed series conductivities exceeding benchmark value 1 mS cm–1 at room temperature. Detailed investigations, including neutron powder diffraction, pair distribution function analysis, first-principles calculations, performed gain an insight mechanisms behind adjustment. Furthermore, these materials exhibit enhanced deformability due increased metal framework, enabling high-performance ASSB prototypes operatable low stacking pressures (<10 MPa). These advancements deepen our understanding superionic mark important step toward practical application ASSBs future.

Sulfide-based all-solid-state batteries are currently a focal point of research for next-generation energy storage solutions. However, the poor antioxidative stability sulfide electrolytes limits their practical applications. In this study, we strengthen sulfur-related bonding interactions by regulating local charge density surrounding sulfur atoms, thereby enhancing oxidative electrolytes. First-principles calculations and experimental results demonstrate that substituting certain in Li9.9SnP2S11.9Br0.1 with oxygen leads to an increase electronic around unsubstituted atoms reduction cation–anion bond lengths, which subsequently strengthens bonds including P–S Sn–S. Remarkably, tailored electrolyte also exhibits significant improvements air chemical compatibility halide Batteries constructed obtained Li9.9SnP2S10.9Br0.1O1.0 demonstrated greatly enhanced electrochemical performance. Our highlight how distribution regulation enhances electrolytes, offering valuable insights creating high-performance batteries.

Abstract All‐solid‐state lithium metal batteries (ASSLBs) are promising for high energy and safety. Halide‐based solid‐state electrolytes, characterized by ionic conductivity a notably wide electrochemical window exceeding 4.3 V, hold significant promise compatibility with high‐energy cathodes. However, oxygen in cathodes exhibits strong tendency to interact the central cation halide electrolyte, forming an unstable cathode‐electrolyte interface (CEI) leading cathodic degradations. Herein, pre‐oxidation strategy is proposed Y based leveraging pre‐establish robust Y─O bonds within electrolyte structure Li 2 YCl 2.5 Br 1.5 O 0.5 (2LO‐0.5). The 2LO‐0.5 effectively hinder uncontrolled interactions 3 ⁺, which would otherwise lead formation of oxidizable YOCl. This stabilization promotes thin, stable Y₂O₃‐based CEI against LiNi 0.83 Co 0.11 Mn 0.06 (NCM83). Therefore, ASSLB assembled NCM83 demonstrates initial discharge‐specific capacity 208 mAh g −1 retained 80.6% its after 1000 cycles, attributed film derived from pre‐oxidized strategy. work offers new insights regulating non‐redox reaction between electrolytes oxide cathodes, promoting rational design high‐performance electrolytes.

Combined solid electrolytes address cathode-anode compatibility in all-solid-state Li-ion batteries (ASSLBs), yet interface stability and ion transport mechanisms between different remain unclear. Herein, we investigate Li6PS5Cl (LPSC), Li3InCl6 (LIC), Li1.75ZrO0.5Cl4.75 (LZOC) composite through electrochemical analysis operando X-ray photoelectron spectroscopy. Our results reveal that the electrostatic potential difference LPSC LIC inhibits Li+ migration, leading to decomposition of into InCl3 LiCl, causing battery failure. In contrast, LZOC forms an oxygen-rich interphase with LiCoO2 (LCO), showing better interfacial stability. The promotes diffusion, maintaining even as decomposes, thereby preventing severe degradation LZOC. Therefore, LCO-LZOC cathode exhibits performance than LCO-LIC. This study elucidates basic mechanism reaction diffusion sulfide–halide emphasizes key role electrolyte ASSLBs failure pathways.
