State of Charge In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate.
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.
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.
Lithium ions must be able to move freely and reversibly between and within the battery’s electrodes. Several factors can impede this free movement and can cause a battery to prematurely age and degrade its state-of-health (SoH). Over time, successive charging and discharging causes damage to the battery’s materials.
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 .
Both modes of lithium loss reduce the charge “currency” or lithium inventory, and thus the battery’s capacity, because there will be a diminished amount of lithium freely available to convey charge between the positive and negative electrodes.
