Customer ServiceSeveral factors contribute to battery degradation. One primary cause is cycling, where the repeated charging and discharging of a battery causes chemical and physical changes within the battery cells. This leads to the gradual breakdown of electrode materials, diminishing the ability of the battery to hold a charge.
Therefore, nearly all the over-discharged batteries present a linear degradation rate as the over-discharge cycling proceeds, 0.05%/cycle. The impact of current rate on the degradation is revealed by influencing the cycle time, whereby a high current rate usually brings about a shorter cycle time and further accelerates the degradation.
Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.
The degradation of lithium-ion battery can be mainly seen in the anode and the cathode. In the anode, the formation of a solid electrolyte interphase (SEI) increases the impendence which degrades the battery capacity.
In comparison with the stable degradation of the normal-cycled battery (0.02%/cycle), the capacities of the over-discharged batteries degrade violently during the first few over-discharge cycles, and then the degradation slows; finally, a linear degradation is presented with a degradation rate of 0.05%/cycle.
Several parameters, such as capacity degradation rate, temperature rise, temperature difference and voltage are discussed correspondingly. It is found that battery capacity experiences significant degradation under the abusive condition of overcharge cycle, and the current rate is revealed to affect the degradation rate greatly.
