Mathematical Models and Methods for Lithium-ion Batteries

In modern lithium-ion batteries, a variety of physicochemical processes occur simultaneously on various size and time scales. To systematically examine their influence and interactions within a battery, mathematical models are developed that represent the respective processes using partial differential equations. Using numerical methods, specific parameters of a battery can be calculated, such as the cell voltage as a function of state of charge. These models are continuously evolving to, for example, account for aging effects. [>> more]

Crystal growth under the influence of electromagnetic fields

n order to produce semiconductor components used in computers, mobile phones, laser devices or solar cells, semiconductor (single- and poly-) crystals of high quality are needed. The growth process of such crystals is complex and quite often expensive. It is important to find strategies to reduce the costs of the growth process and to improve the quality of the produced crystals. In this context electromagnetic fields often play an essential role. Applied mathematics, in particular the techniques of modeling, analysis, and simulation, is used to support the development of growth processes. [>> more]
