What is battery degradation?

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.

How does battery degradation affect energy storage systems?

Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.

How is battery deterioration predicted?

Battery deterioration is predicted using a machine learning approach called support vector machines (SVM). SVM models anticipate the degree of battery degradation or estimate the battery’s remaining usable life by using historical data and battery performance characteristics, including voltage, current, temperature, and cycle count .

How a lithium ion battery is degraded?

The degradation of lithium-ion battery can be mainly seen in the anode and the cathode. In the anode, the formation of a solid electrolyte interphase (SEI) increases the impendence which degrades the battery capacity.

What is the dominant aging mode for battery capacity decay?

This means that both ANOR and ANOVA analyses lead to the consistent conclusion that LLI is the dominant aging mode for battery capacity decay at different aging phases. From the results of the ANOVA analysis, it can be obtained that LAMp is also dominant in the aging phases of 100–93.3%, 100–86.7%, and 100–80%.
