The primary aging effect in a Lithium-ion battery is increased internal resistance (caused by oxidation of the plates). This doesn''t affect the Ah capacity, but it does reduce voltage and waste power at high current.

For a constant current-constant voltage charging mode, the incomplete discharging process affects not only the initial state but also processed variables of the subsequent charging profile, thereby mainly limiting the applications of many feature-based capacity estimation methods which rely on a whole cycling process.
Constant voltage charging current and time lithium batteries are usually discharged at different currents during use, and often cannot experience a complete and
As a battery discharges, its voltage drops. This is because the chemical reaction that produces the electricity is not 100% efficient, so some of the energy is lost as heat. The voltage also drops because of internal resistance within the battery itself.

In this research, we propose a data-driven, feature-based machine learning model that predicts the entire capacity fade and internal resistance curves using only the voltage response from constant current discharge (fully ignoring the charge phase) over the first 50 cycles of battery use data.

Both effects occur as a battery is drained. The open circuit voltage goes down and the internal resistance goes up. Note that open circuit voltage is specifically measuring just the voltage the battery puts out with the internal resistance taken out of the equation. That is because there is no current thru that resistance, hence no voltage drop

Constant voltage (CV) charge phase data helped to determine battery state of health. According to technology, CV current and/or CV duration through aging are exploited. A simple method that can be easily implemented in a BMS. Lithium battery performances degrade even at rest time that means when electric/hybrid electric vehicles are in the parking.
Over time, batteries can lose their capacity to hold charge even if their voltage remains high. Why do batteries lose voltage over time? Batteries lose voltage over time due to several factors like the natural degradation of chemical components, repeated charge-discharge cycles, and environmental conditions such as temperature.
As a note, one of the reasons Power Sonic chose lithium iron phosphate over other types of lithium ion chemistries is because the voltage is very similar to an SLA battery – with lithium voltage being just slightly higher at 12.8V (SLA batteries being 12V). This similarity in voltages also means the way the batteries will feature similar charging characteristics.
Since voltage also drops as the battery discharges, the increased resistance causes it to reach cutoff voltage earlier and so reduces its effective capacity. An old lithium-ion battery which is not powerful enough to run the device it was designed for may still be useful in a lower current application.
Lithium-ion batteries unavoidably degrade over time, beginning from the very first charge and continuing thereafter. However, while lithium-ion battery degradation is unavoidable, it is not unalterable. Rather, the rate at which lithium-ion batteries degrade during each cycle can vary significantly depending on the operating conditions.
(Why Does) As a battery discharges, the voltage it produces decreases. However, the amount of voltage lost during discharge depends on the type of battery and how it is used. For example, lead-acid batteries typically lose about 2% of their voltage per cell per hour when discharged at a constant rate. As a battery discharges, its voltage drops.
Particularly, the capacity researched in this paper refers to the charging capacity. The remaining capacity of a lithium-ion battery is affected by many factors, such as external environmental loads, the number of charging and discharging cycles, the value of discharging current and so on.
As it turns out, the answer to this question is a bit complicated. Batteries will indeed lose some of their charge when left unused for extended periods of time, but the amount of power loss will vary depending on the type of battery and other factors.
However, one potential downside of lithium-ion batteries is their tendency to experience a voltage drop when under load. This voltage drop is caused by the battery’s internal resistance, which increases as the battery discharge rate increases.
