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.
Reference researched the decay law of lithium-ion battery capacity in a low temperature environment, and found that the capacity decay rate of the battery increases with the decrease of temperature at 0 °C, − 5 °C, − 10 °C, − 15 °C, and − 20 °C respectively.
During the whole process of battery aging, LAM contributes little in the early stage and tends to accelerate in later stages of battery lifetime. LLI include the formation, thickening, breakage, and reconstruction of SEI films. In addition, CEI films also consume a small amount of active lithium.
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.
Calendar aging of lithium-ion battery can be explained by the Arrhenius equation . where, both and are the SOC dependent terms, is the gas constant, and z is the power law parameter used to denote the dependence of time parameters. 3.5. State of Charge
The capacity degradation of lithium batteries can be qualitatively identified and quantitatively analyzed through the characteristic parameters of IC curve, such as loss of active materials, loss of lithium ions, battery chemical changes, underdischarge and undercharge.
