Dual Electrolyte Additives to Achieve High-Rate Cycle Performance of Lithium-Ion Batteries with a High Nickel Cathode

High-Ni cathodes promise high energy density but suffer from interfacial degradation. Here, a dual-additive electrolyte—trimethylsilyl phosphate to scavenge HF and adiponitrile to tailor Li⁺ solvation—enables a robust, LiF-rich CEI, boosting...
