To gain a better insight into over-discharge behavior, an experimental study is carried out in the present work to investigate the impact of current rate, i.e. cycle rate, charge rate and discharge rate on the degradation behavior of a lithium-ion battery under over-discharge condition.
The influence on battery from high charge and discharge rates are analyzed. High discharge rate behaves impact on both electrodes while charge mainly on anode. To date, the widespread utilization of lithium-ion batteries (LIBs) has created a pressing demand for fast-charging and high-power supply capabilities.
Combining the results in The electro-thermal behaviors of the over-discharged lithium-ion batteries in combination with different current rates Section, it can be found that when a battery is over-discharged to 0.5 V at a rate of 0.5C, its discharge capacity is obtained at 1222 mAh.
After the over-discharge cycling, the batteries discussed in Impact of cycle rate on the degradation behavior of lithium-ion battery during over-discharge cycling Section were resumed with normal cycling, that is, they were cycled between 2.75–4.2 V at a rate of 0.5, 1, 2 and 3C, respectively.
When a battery is discharged at a high rate, its discharge time shortens, leading to a short cycle time and a fast degradation. In short, the charge/discharge rate exhibits little impact on the degraded capacity within each over-discharge cycle; however, it may affect the degradation behavior by varying the required cycle time.
The failure behaviors of NCM/Gr battery are explored by accelerated aging test. The variations of electrodes are compared under different high discharge rates. The influence on battery from high charge and discharge rates are analyzed. High discharge rate behaves impact on both electrodes while charge mainly on anode.
