Jonghyun Park, Associate Professor, Department of Mechanical and Aerospace Engineering, Missouri University of Science & Technology

This talk will delve into the complexities of batteries, which are electrochemical devices that convert chemical energy into electrical energy. The energy conversion process is governed by internal physical and electrochemical reactions involving multiple interrelated factors, such as materials, manufacturing processes, and management. The discussion will explore harnessing the synergy between manufacturing, management, and materials to create more efficient, safer, and longer-lasting batteries.

Shaping the structures through electrode engineering is vital for consistently producing high-quality batteries. The presentation will cover various methods, including structured electrodes for achieving high energy density using extrusion and aerosol jet printing, electric-field-processed electrodes, and femtosecond laser-processed electrodes.

Battery optimization and management via mathematical models are essential tools for understanding the electrochemical processes inside a battery, predicting/optimizing performance, and designing/refining manufacturing processes. The presentation will cover topics such as battery degradation processes and new charging algorithms for extremely fast charging. 

To optimize a battery's energy density, power density, and durability, the final consideration must be the materials used. The presentation will introduce new ideas for material synthesis and processing, leading to property enhancements.

Faculty, students, and the general public are invited.
