2020 Virtual undergraduate Research symposium
Scalable Nanomanufacturing of Next Generation Battery Materials
PROJECT NUMBER: 7
AUTHOR: Jerry Birnbaum, Chemical and Biological Engineering | MENTOR: Colin Wolden, Chemical and Biological Engineering
ABSTRACT
—
Several different methods for the synthesis of anhydrous Na2S for use in next generation batteries were explored in this research project. A solvent based approach was explored by synthesizing Na2S from sodium metal and H2S in a couple different solvents. Another approach explored was the thermal dehydration of widely available Na2S hydrate. The materials obtained from these different synthesis methods were analyzed using TGA and XRD.

Jerry Birnbaum is a junior in the Chemical and Biological Engineering department at the Colorado School of Mines. He is currently developing the scalable synthesis of sodium sulfide nano-particles for use in next generation batteries. The sodium sulfide nano-particles can be used for cheap, large scale storage which is necessary for the expansion of renewable resources. In the future he hoped to extend process for sodium sulfide to cathode formation and use in solid state electrolytes.
A nice project! I had a few questions: Can you explain what method was used to calculate particle size? Does this method have any assumptions about the shape of the particle? Did you conduct any microscopy to elucidate the particle shape/size?
Thanks for the nice poster. All the best!
