Battery degradation refers to the gradual decline in the ability of a battery to store and deliver energy. This inevitable process can result in reduced energy capacity, range, power, and overall efficiency of your device or vehicle. The battery
Battery degradation refers to the gradual loss of a battery''s ability to hold charge and deliver the same level of performance as when it was new. This phenomenon is an inherent characteristic of most rechargeable batteries, including lithium-ion batteries, which are prevalent in various consumer electronics and electric vehicles.
The steady decline in a battery''s capacity to store and release energy over time is referred to as capacity fade in battery energy storage systems (BESS). This phenomenon is especially important for rechargeable batteries
When a lithium-ion battery is repeatedly charged and discharged, lithium ions get trapped in places they aren''t supposed to be, which alters the battery''s internal structure. This SEI (solid electrolyte interface) layer forms and thickens, impeding ion movement.
Why does the battery capacity decay? Batteries should always be calculated for their capacity decay and final life. Capacity decay to 80% requires replacement of the battery pack, and the final life limit of the battery pack should change depending on the application, user preferences, and company guarantees.
The steady decline in a battery''s capacity to store and release energy over time is referred to as capacity fade in battery energy storage systems (BESS).

The energy storage of a battery can be divided into three sections known as the available energy that can instantly be retrieved, the empty zone that can be refilled, and the unusable part, or rock content, that has become inactive as part of use and aging. Figure 1 illustrates these three sections. Figure 1: Aging battery [1] Batteries begin fading from the day they are

1. Structural changes of cathode materialsThe positive electrode material is an important source of lithium-ion batteries. When the lithium-ion battery is removed from the positive electrode, in order to maintain the neutral state of the material, the metal element will inevitably be oxidized to a high oxidation state, which is accompanied by the change of composition. The
Lithium-ion batteries (LIBs) are extensively employed in electric vehicles (EVs) and energy storage systems (ESSs) owing to their high energy density, robust cycle performance, and minimal self-discharge rate [].As the energy supply and storage unit, the cycle performance of LIBs determines the longevity of the products.
However, with the application in a long time and complex environment, the aging problems of lithium batteries such as capacity decay, power decay and internal resistance increase gradually limit the development of new energy vehicles [2]. The service life of electric vehicles depends on life of lithium batteries. Therefore, accurate prediction of lithium battery

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.
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.
Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.
Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
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.
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.
