The demands for higher energy density, longer cycle life, and faster charging in the automotive industry, are the pillars of Li-ion and beyond battery research. Interestingly, each of these pillars is closely linked to mechanical stress evolution in electrode materials.
This 45-minute webinar will demonstrate how advanced multiphysics simulation — that integrates electrochemical, mechanical, and thermal domains — can be leveraged to model and predict stress evolution and distribution across scales from individual, active material particles to the cell and module levels. This multiscale modeling approach enables a deeper understanding of physic degradation mechanisms, helps identify the root causes of mechanical failure, and supports decisions for designing more robust battery systems. An audience Q&A session will follow the technical presentation.
Speaker:
Rohan Bokil, Battery Applications Engineer at Gamma Technologies
Rohan Bokil serves as a Staff Engineer at Gamma Technologies, where he has worked since 2020. He previously worked within the engine mechanics group, specializing in assisting customers with multibody dynamics models of engine subsystems. This role involved detailed analysis of complex mechanical systems under various loading conditions to enhance performance and reliability. In 2024, Rohan transitioned to the battery applications team. Leveraging his extensive experience from the engine mechanics group, he currently focuses on mechanical deformation and its effects on electrochemical performance for energy storage cells. Through this work, he plays a key role in advancing the understanding and modeling of energy storage systems, ensuring their safety and efficiency under real-world operating conditions. Rohan holds a degree in mechanical engineering from Clemson University.
