- •
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.
