Electro-chemo-mechanics in solid-state batteries and the understanding on composite cathode issues

The lack of comprehensive understandings to many fundamental problems hinders the practical applications of solid-state energy storage techniques, which usually originate from the complicated multi-physical couplings spanning across multi-scale. In this talk, Dr. Tu will share his research in the effort of investigating electro-chemo-mechanical problems laying behind these applications, including the heterogeneous transport and reactions of electrons and Li-ions in the solid-state batteries, the understanding of dendrite problem, and the development of nanoscale and continuum-scale modeling.

Dr. Howard Qingsong Tu is an assistant professor in the mechanical engineering department, and runs the clean energy and water lab (www.CewLab.org). He got his Ph.D. degree from the University of California at Berkeley in 2017. He was a postdoc researcher in the material science division at Lawrence Berkeley National Lab from 2017-2021. His research has focused on developing sustainable innovative technologies for energy storage systems (such as solid-state batteries) and water desalination systems (such as reverse osmosis and capacitive deionization), with the close-loop data-simulation-experiment approach
