Halide Electrolytes¶
1. Multi-anion/cation engineering enables fast ion transport and stable interfaces in Zr-based halide electrolytes for all-solid-state batteries¶
Source: Chemical Science (2026), d6sc04008j · 📅 2026-08-01 · ↗ Open paper
Proposes a synergistic multi-anion and cation co-doping strategy to create a highly amorphous Zr-based halide electrolyte, Li2.25Zr0.75Al0.25Cl4.2O0.8F0.2, starting from Li2ZrCl6. The disordered structure delivers fast Li-ion transport together with improved interface stability against electrodes, showing how co-substitution can simultaneously tune transport and interfacial behavior in halides.
Relevance to DENG.Group
Directly relevant to Yan Li (halide degradation/transport) and Mengke Li (ion transport mechanism, thermal properties) — amorphization vs. transport trade-offs are exactly the kind of question their simulations can address.
2. Halide Solid-State Electrolytes for all-Solid-State Lithium Batteries¶
Source: Advanced Energy Materials (2026), 10.1002/aenm.71414 · 📅 2026-08-01 · ↗ Open paper
Comprehensive review systematically summarizing recent advances in halide electrolytes by correlating crystal chemistry, defect chemistry, and ion transport with interfacial behavior in full cells. Covers synthesis, doping strategies, stability against Li metal and high-voltage cathodes, and remaining challenges for commercialization — a structured map of the halide-SSE field as of 2026.
Relevance to DENG.Group
A must-read reference for the halide electrolyte sub-team (Yan Li, Mengke Li) — useful for positioning their simulation work on degradation and transport within the current experimental landscape.
Interfaces & Interphases¶
3. Inorganic interphases for a stable garnet solid electrolyte-lithium metal interface¶
Source: Energy Storage Materials (2026) · 📅 2026-08-01 · ↗ Open paper
Studies how inorganic interphases between garnet LLZO and lithium metal control interfacial resistance, stability, and nonuniform lithium deposition. The analysis connects interphase composition and properties to dendrite initiation at the electrolyte/Li interface, and outlines design criteria for artificial interphase layers that stabilize the LLZO/Li contact.
Relevance to DENG.Group
Sits at the intersection of Umang's heterogeneous-interface simulations and Shoutong's dendrite modeling — interphase-property/dendrite-nucleation links are a natural target for the group's simulation toolchain.
4. Thin-Film Engineering of Artificial Interphases for Lithium Batteries¶
Source: Small (2026), 10.1002/smll.74311 · 📅 2026-08-01 · ↗ Open paper
Review establishing a process-structure-function-application framework for thin-film artificial interphases in lithium batteries, going beyond a material-by-material survey. Covers deposition routes, interphase mechanics and ion transport, and how engineered films improve stability and safety of Li-metal and solid-state cells, with transferable design principles across chemistries.
Relevance to DENG.Group
Useful background for Umang and Shoutong — thin-film artificial interphases are a concrete interface-engineering strategy their simulations could help rationalize and optimize.
