💡 Novelty & Significance:
The novelty lies in using electric-field-oriented interfacial solvent engineering with 4-cyano-tetrahydropyran to shield vulnerable ether oxygens from the cathode, enabling high-voltage ether electrolytes. This suppresses oxidative decomposition and forms an inorganic-rich interphase, achieving 4.8 V stability and a 331.2 Wh kg–1 pouch cell with 83.5% retention after 600 cycles—significantly advancing practical high-energy Ni-rich lithium-ion batteries.
