Battery degradation refers to the progressive loss of a battery’s capacity and performance over time, presenting a significant challenge in various applications relying on stored energy . Figure 1 shows the battery degradation mechanism. Several factors contribute to battery degradation.
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.
Thus, a review of this area's understanding is important. It is essential to know how batteries degrade in EVs to estimate battery lifespan as it goes, predict, and minimize losses, and determine the ideal time for a replacement. Lithium-ion batteries used in EVs mainly suffer two types of degradation: calendar degradation and cycling degradation.
As batteries degrade, their capacity to store and deliver energy diminishes, resulting in reduced overall energy storage capabilities. This degradation translates into shorter operational lifespans for energy storage systems, requiring more frequent replacements or refurbishments, which escalates operational costs.
Most battery degradation studies refer to modelled data without validating the models with real operational data, e.g. [10, 12, 17]. In this research, data from a BESS site in Herdecke (GER) operated by RWE Generation is used to analyse the degradation behaviour of a lithium-ion storage system with a capacity of 7.12 MWh.
Battery degradation affects each battery cell in the battery energy storage system (BESS), which in turn causes capacity fading throughout the system. Waldmann et al. estimated an 18% capacity fade in lithium Li 0.89 NiCoO 2 during the first charge discharge cycle .
