文摘

•: The external short circuited battery is cycled 1000 times at 0.6C with 30% DOD.
•: Aging mechanism during long-term cycling of short circuited batteries is studied.
•: The polarization of LiCoO₂ electrode is one of major reason of capacity fading.
•: The structure degradation of LiCoO₂ can also cause the capacity loss of battery.
