💡 Novelty & Significance:
The novelty lies in a nonflammable TEP/THF hybrid electrolyte where weakly coordinating THF boosts anion-derived inorganic interphases and fast Na+ transport. Significance: 18650 cylindrical SIBs achieve 80.6% capacity retention after 300 cycles at 80 °C, pass nail penetration without combustion (peak 88.9 °C), and support layered oxide cathodes, enabling high-temperature, high-safety grid storage.
