dc.description.abstract | This study presents a novel method that combines dV/dQ curves and entropy profiles to accurately delineate the phase transition boundaries of battery electrodes. This integration provides a comprehensive understanding of the phase transition behavior, enabling precise identification of phase change boundaries. Employing these boundaries, phase-based capacity loss tests are conducted under galvanostatic aging cycles, allowing for the observation of battery aging characteristics across different aging ratios. The findings obtained from these tests offer valuable insights into the aging mechanisms and performance degradation associated with specific phases. Consequently, this research enables the development of strategies to optimize the charging scheme, mitigate capacity loss, and enhance battery performance, ultimately leading to a prolonged battery lifespan. Overall, this study contributes to advancements in accurately characterizing phase transitions, optimizing charging schemes, and improving the overall performance and longevity of batteries. | - |
