Several 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.
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.
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.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
In addition, the battery degradation mode also includes the internal resistance increase (RI) and loss of electrolyte (LE). The internal resistance increase may directly lead to the battery power fade of the battery, and the battery available capacity would also decrease as the charge and discharge cut-off voltage stay constant.
With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components . Mechanical stress resulting from the expansion and contraction of electrode materials, particularly in the anode, can lead to structural damage and decreased capacity .
