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 expanding use of lithium-ion batteries in electric vehicles and other industries has accelerated the need for new efficient charging strategies to enhance the speed and reliability of the charging process without decaying battery performance indices.
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.
Fast charging is conflict with extending the lifespan of lithium ion battery to mitigate the high cost. Hence, it becomes necessary to identify the battery aging mechanisms and quantify the effects that different charging stresses introduce to the battery.
One of the major issues that has hindered step-change advances in LIB performance is the decline over time in the charge that a battery can deliver (defined as ‘capacity fade’), and its impact on performance. A key location for electrochemical degradation processes is the interface between the electrolyte and the electrode active particles.

$begingroup$ You''re probably confusing what "last longer" means. You will only get 80% of energy per charge cycle, but that cycle will "damage" your battery 5x less than charging it to 100%.So in far future, you get 5x 80% = 400%, instead of 1x 100% = 100% of the power. In other words, you will be able to charge the battery many more times, also getting …

Second, at the end of the cycle charging, when the current is too high, lithium ions will concentrate on the electrode surface and precipitate out lithium metal, causing LLI. It also contains a situation where a particular electrode is peeling off, leading to a reduction in the ''lattice'' that can hold lithium ions, which also causes a decrease in capacity, as shown on the right …
Charging a Lithium battery is very different from charging a Lead-Acid battery. The most crucial difference is that a Lithium battery charges at a lower voltage than required to charge a Lead-Acid battery. Charging a Lithium battery with a higher Lead-Acid charging voltage will cause the Lithium Battery''s Battery Management System (BMS) to self-protect and disconnect the …
