Solid Electrolytes & Dendrite Mechanics

1. 2026 Roadmap on Next-Generation Solid Electrolytes for Battery Materials

Source: Materials Futures (10.1088/2752-5724/ae5120) · 📅 2026-07-01 · ↗ Open paper

A community roadmap envisioning solid electrolytes as active, rather than passive, battery components. Covers advances in sulfide, oxide, halide, and polymer SEs, with emphasis on scalability, interface engineering, and ML-accelerated discovery. The roadmap identifies key bottlenecks in manufacturing, mechanical integrity, and cost reduction for commercial SSBs.

Relevance to DENG.Group

Provides strategic context for the group's overall research direction. Useful for positioning Jerry's program within the field landscape and identifying emerging funding/collaboration opportunities.

ML Interatomic Potentials

2. Experimental Validation of Universal Machine Learning Interatomic Potentials for Lithium-Ion Dynamics in Solid Electrolytes via 7Li NMR

Source: ChemRxiv (10.26434/chemrxiv.15002480) · 📅 2026-06-01 · ↗ Open paper

This preprint demonstrates experimental validation of universal MLIPs (e.g., MACE-MP-0, CHGNet) against 7Li NMR spectroscopy data for lithium-ion dynamics in solid electrolytes. The work benchmarks predicted activation energies and jump frequencies against direct experimental measurements, establishing NMR as a validation tool for ML potentials.

Relevance to DENG.Group

Directly relevant to Yanhao Deng's work on validating ML potentials for solid electrolytes. The NMR validation approach could complement the group's simulation-driven discovery pipeline.
