Summary
Second-life batteries offer a promising solution for improving renewable energy storage while reducing battery waste and system costs. As electric vehicle adoption grows, large numbers of retired batteries can still be reused in stationary energy applications, especially for solar, wind, microgrid, and building energy systems.
This Special Issue aims to collect high-quality research on the design, safety, control, management, and practical application of second-life battery energy storage in renewable energy systems. It welcomes original research and review papers that address technical, economic, environmental, and policy-related aspects of battery reuse for clean and sustainable energy systems.
Suggested themes include:
- Testing, grading, and state-of-health estimation of second-life batteries
- Battery management systems, safety, and thermal control
- Integration of second-life batteries with solar, wind, and hybrid renewable systems
- Energy management, optimization, and control strategies
- Applications in microgrids, buildings, and off-grid energy systems
- Techno-economic analysis, life-cycle assessment, recycling, and circular economy approaches
