Summary

Dr. Tuanan da Costa Lourenço presents a talk on how computational materials science can advance the development of new battery devices. He begins with a personal introduction, highlighting his journey from a chemistry bachelor to a postdoctoral researcher in computational materials design. He explains the basic working principle of batteries, emphasizing the role of the anode, cathode, and electrolyte. He then introduces the computational methods used in his research group, particularly Density Functional Theory (DFT) and classical Molecular Dynamics (MD), and how they complement each other to study battery materials. The talk focuses on sodium-ion batteries as a low-cost and sustainable alternative to lithium-ion batteries, discussing their advantages and challenges. He presents two case studies: one on the effect of ionic liquid crystals on a lithium-oxygen battery electrolyte, and another on sodium-ion electrolytes. In the first case, he shows how MD simulations helped explain unexpected experimental trends in ionic conductivity and viscosity. In the second, he discusses ongoing work on confined systems. Throughout, he emphasizes the importance of combining simulations with experiments to gain atomistic insights and guide material design. The talk concludes with a summary of key findings and future directions.
