Similarly, in battery energy storage systems (BESS), battery degradation can limit the amount of energy that can be stored and delivered, impacting the overall efficiency of the system. It''s important to note that while the term battery degradation often conjures up images of a faulty or defective battery, it is, in fact, a natural and expected phenomenon. Just like the components

Although nickel-cadmium batteries lose about 40% of their charge storage spontaneously and without consumption within the first quarter after the last charge date, this amount of energy is automatically depleted for SLA acid batteries. Loss of 40% of the stored energy occurs within one year after the last charging date.
Today''s electrochemical energy storage systems and devices, both mobile and stationary, often combine different charge storage mechanisms whose relative contributions are rate dependent (Fig. 1).Physically, charge storage mechanisms can be classified into two categories: capacitive and faradaic (Fig. 1).Both charge storage mechanisms differ by their
