Webinar Description
Hosted by: ACerS Washington DC/Maryland/Virginia Section
Friday, September 26, 2025; 12p.m. – 1p.m. Eastern US time
Sponsored by the ACerS Washington DC/Maryland/Virginia Section, the September webinar will feature one speaker: Ion Conducting Oxides for Electrochemical Energy Conversion and Storage
DESCRIPTION
Ion Conducting Oxides for Electrochemical Energy Conversion and Storage
Rate capability is a limiting factor in solid oxide fuel cells (SOFCs), solid oxide electrolysis cells (SOECs), and oxide-based solid-state lithium (SSLiBs) and sodium (SSNaBs) batteries due to high area specific resistance (ASR). Lower ASR SOFC, SOEC, SSLiB, and SSNaB structures would enable higher power density and lower cost, dramatically improving market adoption of these energy conversion and storage technologies. In this presentation we will explain the roles of solid ion-conductor composition, structure, and interfaces in reducing ASR to achieve extremely high current densities. Results will be presented for GDC based SOFCs/SOECs, Li-garnet based SSLiBs, and NASICON based SSNaBs, and similarities between these dissimilar materials and electrochemical devices elucidated. Moreover, we will demonstrate that SOFC and SOEC current densities over 5 A/cm2 can be achieved at 650°C, and SSNaB and SSLiB current densities of 30 mA/cm2 and 100 mA/cm2, respectively, can be achieved at room temperature, based on these similarities.
BIOGRAPHIES
Dr. Eric D. Wachsman, Director, University of Maryland Energy Innovation Institute
Dr. Eric D Wachsman is the Director of the Maryland Energy Innovation Institute, the William L. Crentz Centennial Chair in Energy Research and a Distinguished University Professor with appointments in both the Department of Materials Science and Engineering, and the Department of Chemical Engineering at the University of Maryland.
