Explore the materials science fundamentals behind rechargeable battery technology through this comprehensive 9-hour course from nanoHUB-U. Master the equilibrium and time-dependent responses of existing and emerging Li-ion battery chemistries while understanding how material selection and processing impact performance and reliability. Learn essential concepts including battery potential, charge figures of merit, energy and power relationships, and polarization losses. Delve into electrochemical thermodynamics, covering equilibrium principles, electrochemical potential, and thermal effects across different material systems. Examine the critical role of tortuosity and porosity in porous electrodes, including processing effects, inhomogeneities, correlations, and anisotropy. Study interfacial reactions through the Butler-Volmer relation, interface-related processes, and dendrite formation in rechargeable batteries. Investigate battery architectures and design guidelines, including electrolytes, salts, reaction zone models, advanced architectures, and porous electrode theory. Gain practical insights through example applications such as intercalation, SEI formation, and dendrite growth, while learning to integrate experimental microstructural aspects with coarse-grained properties. Develop conceptual guidelines for understanding and improving battery designs, and review current state-of-the-art battery technology and associated metrology methods.
