Abstract:

Li-ion batteries are one of the most popular types of rechargeable batteries for portable electronics. They are multiscale systems with processes occuring at di erent scales. The aim of the mathematical modelling is better understanding of the electrochemical processes in Li-ion batteries as well as prolonging the batteries' lifetime and improving their performance. A broad range of scienti c and engineering problems involve multiple scales. Direct numerical simulations lead to a huge number of degrees of freedom dicult to handle even with supercomputers. From an application perspective it is often sucient to predict the macroscopic properties of the multiscale systems. The goal of the upscaling techniques for Lithium-ion battery models is to develop a method that captures the small-scale e ects on the large scales, but does not require resolving all the small-scale features.
