4+ years of lithium-ion battery R&D experience at BMW in fast charging, degradation mechanisms, and electrochemical diagnostics of silicon-containing cells for EV applications. I work across laboratory and large-format cells, develop electrochemical and analytical methods, and translate battery test data into practical engineering decisions. My expertise includes cell-level aging studies and pack-level charging strategy, with hands-on proficiency in battery laboratory work (clean/dry rooms, glovebox), testing, and electrochemical simulation. I have authored and co-authored peer-reviewed work on SiOx-graphite aging, lithium plating diagnostics, electrolyte salt inhomogeneity, and lithium trapping.
BMW-funded PhD research on fast-charge-induced degradation in silicon-containing lithium-ion cells for EV applications; with industrial rotation in pack-level fast-charging map design, battery cell can corrosion modeling, and cylindrical cell series development. - Established quantitative diagnostic workflows for degradation analysis, including lithium inventory determination (via ICP-OES, micro-GC) and differential voltage analysis. - Identified failure mechanisms in silicon-containing lithium-ion cells (half, pouch, and 4695 cylindrical cells) under varied operating conditions (e.g., charge rates, state-of-charge), and derived mitigation strategies from material to system level. - Developed charging strategies to achieve smooth power profiles, aligned with pack-level requirements and cell-level electrochemical constraints. - Evaluated corrosion kinetics and risk of Ni-coated cell cans under varying conditions (humidity, surface state, electrolyte additives) using physics-based simulation.
- Investigated aging mechanisms (cycle and calendar aging) and rate capability of prismatic (EV32) and cylindrical (4695) battery cells. - Designed and implemented a multiple reference electrode setup for lab pouch cells to enable fast-charging studies. - Developed electrochemical characterization techniques for aged large-format cells.
