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.
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 cycle of charging and discharging plays a large role in lithium-ion battery degradation, since the act of charging and discharging accelerates SEI growth and LLI beyond the rate at which it would occur in a cell that only experiences calendar aging. This is called cycling-based 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.
Consumption of the cell’s lithium ions through SEI growth is one contributing factor to the degradation mode known as loss of lithium inventory (LLI). Because these reactions occur even when the cell is not in use, known as calendar aging, lithium-ion battery degradation is unavoidable.
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.
