In summary, Chen et al. provides a holistic and practicable strategy to designing highly stable interphases for high-voltage cathodes under thermal stress. By integrating multiple inorganic components with complementary properties through electrolyte additives, ultra-stable cycling durability and interfacial robustness are achieved in LCO at 4.6 V and 45 °C. This work not only offers immediate implications for improving high-energy-density lithium-ion batteries but also establishes a CEI design paradigm that could be extended to other cathode materials operating under extreme conditions.
