Research Project Title:

Development of Advanced Metal Anodes for Rechargeable Batteries Using Electrochemical Calorimetry

abstract:The high theoretical capacities (3860 mAh/g) and energy densities of Lithium anode batteries make them attractive storage devices for use in electrical vehicles, which are currently limited by the energy density of today’s Li-ion batteries (~280 Wh/kg cell). However, metallic Li anodes currently do not cycle well, and an unstable solid electrolyte interphase (SEI) can lead to dangerous and undesirable outcomes. The processes underlying these are currently not well understood. This project will involve completion of a single electrode microcalorimeter, which will then be used to provide quantitative measures of thermodynamic changes in the electrochemical reaction processes on a microscopic scale. This will potentially provide meaningful insights into understanding the underlying processes.

Through this SuperUROP, I hope to gain more high-level research experience in Mechanical Engineering, Thermodynamics, and Electrochemistry. I found a passion for thermodynamics and design through my Mechanical Engineering courses at MIT. I am excited to combine the knowledge I have gained through these courses with my experience from performing electrochemical research in high school for this project and hope to publish meaningful results.
