This $296,023 Project Grant, awarded by the National Science Foundation (NSF) Engineering program (CFDA 47.041), supports a collaborative research effort between the University of Texas-Austin and Purdue University to investigate redox heterogeneity and dynamics in composite battery electrodes. The project aims to use advanced synchrotron diagnostics, data mining, and theoretical modeling to understand the relationship between structural defects, chemical heterogeneity, and degradation in lithium-ion battery materials. The research tasks include correlating redox heterogeneity with defects at the individual particle level, determining the spatiotemporal statistics of redox heterogeneity, and examining the impact of local charge heterogeneity on battery cell degradation. This three-year award, running from August 2024 to July 2027, is expected to provide insights that will contribute to developing battery materials with enhanced performance and reliability.
