Sulfide Solid Electrolytes

1. Interface Stability and Kinetics of Sulfide Electrolytes in All-Solid-State Batteries

Source: Advanced Science · 📅 2026 · ↗ Open paper

Comprehensive computational thermodynamic analysis of sulfide solid electrolytes and their electrode interfaces in all-solid-state batteries, mapping interfacial reaction products and kinetic barriers. Provides quantitative stability windows and degradation pathways across the sulfide family, connecting phase diagrams to interfacial resistance evolution.

Relevance to DENG.Group

Reference dataset for Umang's electrolyte/electrode interface modeling and group sulfide-degradation discussions — thermodynamic interface maps can benchmark reactive MD/MLIP-derived interphase predictions.

Polymer Electrolytes

2. Dual-layer composite polymer electrolyte enabling stable lithium-metal batteries

Source: ACS Applied Energy Materials · 📅 2026-08 · ↗ Open paper

Designs a dual-layer composite polymer electrolyte pairing a high-conductivity layer with a mechanically robust one, decoupling the transport and dendrite-suppression roles usually forced into a single phase. The architecture stabilizes lithium plating and improves safety, demonstrating the layered/graded design logic now popular in CPE engineering.

Relevance to DENG.Group

Directly relevant to Naibing's composite polymer electrolyte simulations — layered architectures are a natural next modeling target, and the decoupled transport/mechanics framing maps onto his property-prediction workflow.
