Solid Electrolytes: Transport & Mechanics¶
1. Solid and Quasi-Solid Electrolytes for Zinc Batteries: Balancing Water Activity, Ion Transport, and Interfaces¶
Source: arXiv (2608.29586) · 📅 2026-08-30 · ↗ Open paper
Review of solid and quasi-solid electrolytes for aqueous-adjacent zinc batteries, framing the trade-off between suppressing water-driven parasitics (hydrogen evolution, corrosion, dendritic Zn deposition) and maintaining fast Zn2+ transport and conformal electrode contact. Provides a design-space map across polymer, hydrogel, and composite electrolyte chemistries.
Relevance to DENG.Group
Naibing Wu: the polymer/composite electrolyte design logic and interface-contact discussion transfer directly to his solid polymer and composite simulation work. Also a useful beyond-lithium reference point as the group considers strategy expansion.
Halide Electrolytes¶
2. Elastic properties of amorphous LiTaCl6 solid-state electrolyte¶
Source: Physical Review Materials · 📅 2026-08-29 · ↗ Open paper
Computational study of the elastic behavior of the recently discovered amorphous LiTaCl6 halide solid electrolyte, filling a gap in the mechanical characterization of glassy halide conductors. Links atomic structure to stiffness and mechanical robustness relevant to stack-pressure operation.
Relevance to DENG.Group
Yan Li and Mengke Li: amorphous halides are an emerging branch of their halide electrolyte program; the structure-elasticity methodology complements their degradation and thermal-property simulations. Mechanical moduli also feed into electro-chemo-mechanical interface models across the group.
Interfaces, SEI & Sulfide Chemistry¶
3. Pressure-regulated mechanochemistry at lithium metal-sulfide electrolyte interfaces¶
Source: arXiv (2609.01088) · 📅 2026-09-01 · ↗ Open paper
Presents a process-variable framework coupling interphase chemistry, ion transport, and defect evolution under stack pressure at Li metal/sulfide electrolyte interfaces. Provides a mechanistic interpretation of how pressure steers interphase formation and transport in sulfide solid-state batteries.
Relevance to DENG.Group
Umang Agarwal: stack-pressure-mediated interphase evolution is core to his heterogeneous electrolyte/electrode interface project. Jerry: pressure as a control knob for interphase chemistry connects to the group's electro-chemo-mechanical coupling theme and sulfide interests.
ML Potentials & AI Methods¶
4. Physics-Grounded Materials Artificial Intelligence for Reliable Materials Discovery¶
Source: arXiv (2608.06680) · 📅 2026-08-06 · ↗ Open paper
Perspective on Physics-Grounded Materials AI (PhysMat AI), systematizing the roles physics plays in AI-driven materials discovery: as prior knowledge, descriptors, constraints, verifiers, and infrastructure. Illustrates the framework with catalysis, solid-state electrolytes for batteries, and hydrogen-storage materials.
Relevance to DENG.Group
Yanhao Deng: a strategic map for making ML potential workflows reliability-first (constraints, verifiers) rather than benchmark-chasing, directly applicable to his MLIP development. Jerry: useful framing for grant proposals on trustworthy AI-accelerated battery materials discovery.
