**Core Discovery** - *Oak Ridge National Lab's AI-MD Simulation*:
- Revealed Li⁺ desolvation energy barrier as charge-rate limiting factor (0.72eV barrier = 4C max)
- Designed fluorinated ether solvent reducing barrier to 0.51eV (enabling 15C charging)
**Advanced Characterization Tools** 1. _Neutron Depth Profiling_ (NDP):
- Quantified Li-plating at 1nm resolution during -20°C fast-charge
2. _Cryo-Electron Microscopy_:
- Captured SEI crystallization dynamics (0.1ms temporal resolution)
**Industry Impact** - CATL's Condensed Battery (2024):
- 500 Wh/kg achieved via modulated solvation structure
- Solid Power's sulfide electrolyte:
- Ionic conductivity boosted to 25 mS/cm (2× previous) by suppressing anion mobility
