Monitoring Microscale Inhomogeneity in Lithium-ion Battery Using Multi-Sensor Information and Data-Driven Approaches

Research Project, 2024

Lithium-ion batteries are currently the leading energy storage solution for electric vehicles, due to their favourable electrochemical properties. However, their high cost, limited lifespan, and reliance on scarce metals pose significant challenges. To tackle these issues, extending their service life is crucial, which requires a comprehensive understanding of aging mechanisms, particularly the dependence on electrode microscale inhomogeneity.
The primary objective of this project is to develop an innovative method for monitoring lithiation inhomogeneities in graphite anodes, utilizing multi-sensor information and data-driven approaches. This method will be experimentally examined using an X-ray diffractometer. The results of this project can facilitate the development of refined control strategies that promote homogeneity and adjust for inhomogeneity to improve battery longevity.
