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.
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.
(ii) In a worst-case scenario, the metallic lithium can grow into branch-like structures called dendrites, which can protrude through the insulating separator and short-circuit the battery. This can cause a catastrophic failure mode, as has been seen in high-profile EV fires covered in the media.
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.
As with fast charging, overcharging a lithium-ion battery can result in lithium plating, which kicks off a rapid, snowball effect of degradation. It’s worth noting that the anode can sometimes degrade more rapidly than the cathode.

As the current flows into the battery, the lithium ions are extracted from the cathode and move through the electrolyte towards the anode. 4. Simultaneously, electrons flow through the external circuit, providing power to the connected device or storing energy in the case of a stationary battery system. 5. The lithium ions intercalate into the anode material, storing …
