In this paper, the influence of charging stresses on battery life is systematically analyzed, and the capacity degradation rate model under different charge stresses is established. The main conclusions are summarized as follows: There exists a critical charging current rate, which is 1C for the tested batteries.
It is indicated that before the 650th cycle, within a range of 1C, the charging current rate has no significant effect on 1s resistance increase, but after the 650th cycle, the batteries cycling at 1C rate charging suffer a much faster increase of 1s resistance. It may be caused by the weaker charge acceptance capability due to aging.
The long-term effects of charging current rates and cut-off voltages on capacity degradation and resistance increase are compared. The results show that there exists a critical charging current and a critical charging cut-off voltage. When the charging stress exceeds the critical value, battery degradation speed will be greatly accelerated.
So, reducing charging stresses in an appropriate aging stage is necessary to delay battery aging. When the charging current is lower than the critical value, it is the deciding factor of LAM while its effect on the amount of LLI is not significant, and reducing charging current can restrain LAM.
Furthermore, battery aging mechanisms at various charging currents and cut-off voltages are investigated using incremental capacity analysis. It is indicated that charging current and cut-off voltage should be reduced to retard battery degradation when the battery degrades to a certain extent.
It is because that lithium-ion battery aging mechanisms under different charging current rates and cut-off voltages are not clear, and a quantitative model that describes the relationship between capacity degradation speed and charging stresses has not be established.
