Raphaële J. Clément Professor Materials Department University of California, Santa Barbara, U.S. Date: October 27, 2021 Time: 1300h ET Sponsors: Hiden Analytical, Royal Society of Chemistry, American Chemical Society Materials Letters, JEOL USA, Inc. The development of next-generation solid state ion conductors hinges on an understanding of microscopic diffusion mechanisms and the identification of roadblocks along macroscopic diffusion pathways (e.g., intragrain defects and grain boundaries).
Ming Tang Associate Professor Department of Materials Science and NanoEngineering Rice University, U.S. Date: July 28, 2021 Time: 1000h ET Sponsor: Hiden Analytical During battery (dis)charging, lithium (de)intercalation in electrodes is usually spatially non-uniform across multiple length scales. Such a phenomenon is a major impediment to battery performance and life as it causes energy under-utilization and induces over-(dis)charging, etc. While reaction heterogeneity is often attributed to mass transport limitation, this talk highlights the important roles of thermodynamic factors including elastic…
