Project Title

Quality Control in Mg-Ion Battery Fabrication

Certificate(s): Materials Science and Engineering

I interned with the Arnold Group investigating the inconsistent performance of rechargeable magnesium-ion (Mg-ion) batteries. Mg-ion batteries are an attractive candidate for use in transportation and large-scale energy storage. They have a high theoretical volumetric capacity and are less susceptible to overheating than lithium-ion batteries. During the course of this project, I learned more about solid-state synthesis and the interpretation of X-ray diffraction patterns and impedance spectra. I gained an understanding of how each stage of battery fabrication impacts the performance of the assembled cell, and I became more familiar with the equipment used. My mentor and the other members of the lab taught me a great deal about intelligent experiment design and gave me a sense of life as a full-time researcher.
