Battery degradation refers to the progressive loss of a battery’s capacity and performance over time, presenting a significant challenge in various applications relying on stored energy . Figure 1 shows the battery degradation mechanism. Several factors contribute to battery degradation.
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.
Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy. This capacity loss, coupled with increased internal resistance and voltage fade, leads to decreased energy density and efficiency.
In [ 15 ], it was already demonstrated that the model is applicable for the investigation of cell degradation. The approach was recently applied in [ 16, 17] to analyze the degradation mechanisms in a lithium-ion battery.
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 .
The capacity loss in a lithium-ion battery originates from (i) a loss of active electrode material and (ii) a loss of active lithium. The focus of this work is the capacity loss caused by lithium loss, which is irreversibly bound to the solid electrolyte interface (SEI) on the graphite surface.
Capacity Fade in Lithium-Ion Batteries and Cyclic Aging over
The results show that the lithium loss is the dominant cause of capacity fade under the applied conditions. They experimentally prove the important influence of the graphite stages on the lifetime of a battery. Cycling the cell at SOCs slightly above graphite Stage II results in a high active lithium loss and hence in a high capacity fade.

How to mitigate the problem of battery loss capacity
Li+ battery loss are even higher for Si-based anodes (15-35%) and other anodes with large volume changes and large specific surface areas. Although the battery loss of lithium can be offset by excess cathode loading, the inactive weight in the battery reduces its overall energy density. The need for low cost and high energy density has accelerated the …
