"diluents thought to only improve macroscopic properties like electrolyte viscosity/ ionic conductivity... overcome using ionic liquid-based localized high-concentration electrolyte anion-diluent decoupled solvation... compact contact ion pairs' framework dominates... restructuring provides superior oxidation resistance at cathode/ accelerated ion transport kinetics... retains up to 88% capacity over 200 cycles at 4.5 V... 2.6 Ah pouch cell passed nail penetration tests... electric aviation, consumer electronics, grid storage"
