Implication

This work demonstrates stable cycling of LiCoO2 at 4.6 V in lithium-ion batteries, indicating improved thermal stability and mitigation of interfacial side reactions.

Key Points

Stable cycling achieved at 4.6 V with 81.9% capacity retention over 500 cycles.
The constructed CEI mitigates interfacial side reactions at elevated temperatures of 45°C.
This work includes electrolyte engineering to enhance the solvation environment for CEI formation.
Transformative pathway established for lithium-ion batteries to operate reliably under extreme conditions.
