BU-802: What Causes Capacity Loss?
Batteries begin fading from the day they are manufactured. A new battery should deliver 100 percent capacity; most packs in use operate at less. As the rock content portion of

Understanding what causes capacity loss of lithium battery packs is essential for optimizing performance and extending service life in business-critical applications. You
Abstract: Accurate state-of-charge (SoC) estimation of lithium-ion batteries has always been a challenge over a wide life scale. In this article, we proposed an SoC estimation method
Battery decay, or capacity fade, is a natural and inevitable process. It''s primarily caused by two irreversible mechanical and chemical changes inside the cells: Loss of Lithium
Capacity degradation refers to the gradual loss of a battery''s ability to hold charge, resulting in reduced runtime and overall efficiency. Typically measured in ampere-hours (Ah)

However, it has a key limitation for battery applications: it splits time series into generic, equal-duration windows that ignore the natural charge–discharge cycle.
The method proposed in this paper is not only able to quantitatively analyze the dominant factors of battery capacity decay, but also achieves high accuracy capacity
Capacity degradation refers to the gradual loss of a battery''s ability to hold charge, resulting in reduced runtime and overall efficiency.
At high charging rates, the main causes of capacity deterioration were the loss of active lithium in the battery and the loss of active material from the negative electrode.
Meanwhile, based on the mechanism model analysis method, combined with the decay mechanism of the battery, the capacity performance prediction of the battery is studied, and
