The current research on power battery life is mainly based on single batteries. As known, the power batteries employed in EVs are composed of several single batteries. When a cell is utilized in groups, the performance of the battery will change from more consistent to more dispersed with the deepening of the degree of application.
Service life refers to the lifespan until the LIB capacity drops below the capacity requirements of a power storage system. In this research, the capacity requirement as a remaining capacity which is 80% of the initial capacity is defined.
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
Limiting degradation has been identified as one of the green principles for responsible battery management , as extending battery lifetime decreases costs and environmental burdens associated with the production of new batteries, including material consumption, mining impacts, and greenhouse gas (GHG) emissions .
Almost always, battery scientists and engineers have tested the cycle lives of new battery designs in laboratories using a constant rate of discharge followed by recharging. They repeat this cycle rapidly many times to learn quickly if a new design is good or not for life expectancy, among other qualities.
Comparison of lithium-ion battery life prediction methods. The data-driven method establishes a prediction model based on the statistical laws of historical data, without considering the physical and chemical reactions inside the battery, and can quickly predict the state and life of the battery.

Repurposing Second-Life EV Batteries to Advance Sustainable
6 · By prolonging the service period of these batteries, the need for immediate recycling is postponed, which reduces the energy and resources required for battery disposal and new battery production . Therefore, overall energy costs decrease, the economy becomes more circular, and less GHGs are emitted into the atmosphere, aligning directly with SDGs 7, 12, and 13.
