The construction of stable cathode electrolyte interphase (CEI) is the key to improve the NCM811 particle structure and interfacial stability via electrolyte engineering. In He’s work, lithium hexamethyldisilazide (LiHMDS) as the electrolyte additive is proposed to facilitate the generation of stable CEI on NCM811 cathode surface and eliminate H2O and HF in the electrolyte at the same time, which boosts the cycling performance of Li||NCM811 battery up to 1000 or 500 cycles with 4.5 V cut-off voltage at 25 or 60 °C.

稳定的阴极电解质界面（CEI）的构建是通过电解质工程改善NCM811颗粒结构和界面稳定性的关键。He的工作中，提出使用六甲基二硅氮化锂（LiHMDS）作为电解液添加剂，促进NCM811正极表面生成稳定的CEI，同时消除电解液中的H 2 O和HF，从而提高Li||的循环性能。 NCM811 电池在 25 或 60 °C 时可循环 1000 或 500 次，截止电压为 4.5 V。
