Thermal runaway during high-discharge cycles in lithium-ion pouch cells created a significant safety hazard that necessitated a complete redesign of the thermal management cooling architecture. To solve this, I modeled airflow dynamics across a custom-designed aluminum heat sink using MATLAB and Simulink. The project successfully reduced peak operating temperatures by 18 degrees Celsius during 4C discharge rates while simultaneously increasing the usable energy density of the module by 5 percent. This rigorous testing approach established the reliability metrics required for a senior capstone project and provided a blueprint for modular battery pack construction.

My research during my undergraduate fellowship involved applying Python for large-scale data analysis of battery degradation cycles. I processed over 500 gigabytes of cell cycle data using NumPy and Pandas to identify capacity fade patterns in solid-state prototypes, resulting in a 12 percent more accurate predictive model for cycle life. Additionally, I built a prototype Battery Management System using an Arduino platform that reduced voltage balancing latency by 200 milliseconds. These initiatives improved cell characterization efficiency and allowed for more precise state-of-charge estimation, which directly impacts the long term stability of stationary energy storage systems.
