This article provides a comprehensive review on the battery degradation along the whole cycle life. However, the battery degradation problems still need further research, especially for the high energy density battery with new chemistry including the Ni-rich cathode, Li-rich cathode, lithium sulfur battery, all solid state battery, and so on.
Authors have claimed that the degradation mechanism of lithium-ion batteries affected anode, cathode and other battery structures, which are influenced by some external factors such as temperature. However, the effect of battery degradation on EV and energy storage system has not been taken into consideration.
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.
Researchers have discovered the fundamental mechanism behind battery degradation, which could revolutionize the design of lithium-ion batteries, enhancing the driving range and lifespan of electric vehicles (EVs) and advancing clean energy storage solutions.
Then, based on this Degradation Model, it is believed that the optimized battery design, production and management could effectively improve the battery life. 4. The aging mechanism of battery system At present, there are relatively more studies focus on the aging of a single cell, while there are few studies on the aging of the battery system.
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.

The truth about battery degradation in electric vehicles
The main reason that EV batteries degrade is that they use lithium-ion cells, which start depleting as soon as they''re created. Additionally, as an electric battery goes through charge cycles, it slowly loses its maximum potential, which is known as cycling ageing.
