To find the cause of self-discharge, scientists need to identify the complex chemical mechanisms that trigger the degradation process in the battery. Lithium-ion batteries are rechargeable and use lithium ions to store energy. The cathode and the electrolyte are two key components in lithium-ion batteries.
Self-discharge is the phenomenon of automatic discharge of a battery when it is shelved in an open circuit, which generally manifests as a reduction in the OCV after the battery is stored for a period of time . The self-discharge of lithium-ion batteries is affected by battery state of charge (SOC) .
Factors Influencing Self-Discharge Rates Several factors influence the self-discharge rates in lithium-ion batteries: Temperature: Higher temperatures can accelerate the chemical reactions inside the battery, increasing the self-discharge rate. Conversely, lower temperatures can slow down these reactions, reducing self-discharge.
Lithium-ion batteries are rechargeable and use lithium ions to store energy. The cathode and the electrolyte are two key components in lithium-ion batteries. The battery’s longevity can be influenced by the degradation of cathodes.
In the pre-charge and pre-discharge stage, the lithium-ion battery was first charged at a constant current of 8 C for 5 s, and after standing for 5 s, it is discharged at a constant current of 8 C for 5 s and allowed to stand for 10 s.
So far, the self-discharge in LIBs is comparatively the most studied device up to the pouch cell level. However, in contrast, the self-discharge studies in other rechargeable batteries are in an immature state, and more investigations are required.

Why Lithium Batteries Self-Discharge After Fully Charged?
Self-discharge in lithium-ion batteries can have significant implications for their performance. As the battery loses stored energy over time, its capacity decreases, resulting in reduced runtime and overall efficiency. Additionally, self-discharge can lead to early battery failure if not properly managed.
