Dual electrolyte additives to achieve high-rate cycling 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<sup>+</sup> solvation-enables a robust, LiF-rich CEI, boosting NCM811's stability. This strategy achieves 90.16% capacity retention at 5C, offering a pathway to durable, high-performance batteries.
