Recent research published in IEEE Access sheds light on the potential for second-life applications of electric vehicle (EV) batteries, emphasizing their economic and environmental benefits. As electric vehicle usage rises, the batteries powering them inevitably degrade over time, influenced by factors such as driving habits and charging practices. However, rather than discarding these batteries, the study led by Musa Terkes from the Department of Electrical Engineering at Yildiz Technical University in Istanbul, Türkiye, suggests they can be repurposed for energy storage in various applications.
The research highlights that the feasibility of using these degraded batteries hinges on several technical properties, including remaining capacity, temperature stability, and cycle life. Terkes notes, “Second-life applications can extend existing storage and balance the needs of numerous new batteries,” pointing to a dual advantage: reducing waste and alleviating the demand for new battery production, which is resource-intensive and environmentally taxing.
The commercial implications of this research are significant. By tapping into second-life battery applications, companies can lower costs associated with energy storage solutions. This could be particularly beneficial for businesses looking to enhance their sustainability efforts or offset energy costs. Furthermore, the study outlines the economic landscape surrounding second-life batteries, revealing that their market potential is influenced by various political, economic, and social factors.
The research also delves into the technical aspects of battery performance, including thermal modeling and state of health estimation. Terkes emphasizes the importance of these methodologies in determining how effectively a second-life battery can perform in energy storage systems. “Developing artificial intelligence-based data processing empowered by blockchain to enhance battery features may help sustainable development and clean energy utilization,” he states, suggesting that innovative technologies could play a crucial role in maximizing the utility of second-life batteries.
In addition to exploring the potential applications and challenges of second-life batteries, the study discusses the recycling processes and standards necessary to ensure these batteries can be safely and efficiently repurposed. This holistic approach could not only support the growing energy storage market but also contribute to a circular economy in the battery industry.
As the energy sector increasingly seeks sustainable solutions, the findings from Terkes’ research offer a promising pathway to harnessing the value of used EV batteries. With the right strategies and technologies, second-life batteries could transform not only how we think about energy storage but also how we manage resources in an era that prioritizes clean energy.
