This article provides a comprehensive review on the battery degradation along the whole cycle life. However, the battery degradation problems still need further research, especially for the high energy density battery with new chemistry including the Ni-rich cathode, Li-rich cathode, lithium sulfur battery, all solid state battery, and so on.
Authors have claimed that the degradation mechanism of lithium-ion batteries affected anode, cathode and other battery structures, which are influenced by some external factors such as temperature. However, the effect of battery degradation on EV and energy storage system has not been taken into consideration.
Each time a battery goes through a charging and discharging cycle, it undergoes stress that contributes to its degradation. The depth of discharge, or how much the battery is drained during each cycle, can impact the rate of degradation. Deep discharges and high charge rates can accelerate degradation.
Battery temperature is considered the most important variable affecting battery degradation. Extreme temperatures, whether high or low, accelerate degradation of the battery. Temperatures above or below 25 lead to an increase in the aging rate.
Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
Along with the key degradation factor, the impacts of these factors on lithium-ion batteries including capacity fade, reduction in energy density, increase in internal resistance, and reduction in overall efficiency have also been highlighted throughout the paper.
