Electrochemical surface passivation of LiCoO2 particles at ultrahigh voltage and its applications in lithium-based batteries

LiCoO2 is a cathode material widely used in lithium-ion batteries but suffers from solubilization of cobalt and structural disorder when the voltage is increased to release more capacity. Here the authors show a ternary Li, Al and F-modified LiCoO2 and battery cells with stable cycling behavior over...

Description
Summary:LiCoO2 is a cathode material widely used in lithium-ion batteries but suffers from solubilization of cobalt and structural disorder when the voltage is increased to release more capacity. Here the authors show a ternary Li, Al and F-modified LiCoO2 and battery cells with stable cycling behavior over 4.55 V.
