Thermal Runaway von Lithium-Ionen-Batterien: Einflussfaktoren auf die Materialbeanspruchung druckfester Kapselungen (BestMasters)
by Freyja Galina DaraganTrotz diverser Sicherheitsmaßnahmen auf Zell- und Systemebene kann bei Lithium-Ionen-Batterien (LIB) der „Thermal Runaway“ (TR) auftreten, welcher im Brand und/oder der Explosion der LIB enden kann. In explosionsgefährdeten Bereichen geht hiervon ein besonders großes Risiko aus. Um dieses zu minimieren, kommen Zündschutzarten entsprechend der Norm IEC 60079-0, wie die „druckfeste Kapselung“, zum Einsatz. Auftretende Materialbelastungen durch den TR in einer druckfesten Kapselung können durch verschiedene Faktoren wie das Volumen der Kapselung oder die enthaltene Gasatmosphäre beeinflusst werden. Anhand verschiedener Untersuchungen wurde festgestellt, dass der entstehende Druck nicht ausschließlich von dem Gehäusevolumen, sondern insbesondere von der inneren Oberfläche abhängig ist. Eine Vergrößerung der Oberfläche wirkt demnach druckentlastend. Die Überlagerung des TR mit einer Gasexplosion führt hingegen verglichen mit dem TR unter Luftatmosphäre zu einem Anstieg der Materialbelastung. Bei allen Versuchen herrscht ein proportionales Verhalten zwischen der Systemenergie und der relativen Druckenergie.

Thermal Stability of Metastable Magnetic Skyrmions (Springer Theses)
by Louise DesplatThe energy cost associated with modern information technologies has been increasing exponentially over time, stimulating the search for alternative information storage and processing devices. Magnetic skyrmions are solitonic nanometer-scale quasiparticles whose unique topological properties can be thought of as that of a Mobius strip. Skyrmions are envisioned as information carriers in novel information processing and storage devices with low power consumption and high information density. As such, they could contribute to solving the energy challenge.In order to be used in applications, isolated skyrmions must be thermally stable at the scale of years. In this work, their stability is studied through two main approaches: the Kramers' method in the form of Langer's theory, and the forward flux sampling method. Good agreement is found between the two methods. We find that small skyrmions possess low internal energy barriers, but are stabilized by a large activation entropy. This is a direct consequence of the existence of stable modes of deformation of the skyrmion. Additionally, frustrated exchange that arises at some transition metal interfaces leads to new collapse paths in the form of the partial nucleation of the corresponding antiparticle, as merons and antimerons.

Thermal Transport in Semiconductors: First Principles and Phonon Hydrodynamics (Springer Theses)
by Pol Torres AlvarezStarting from a broad overview of heat transport based on the Boltzmann Transport Equation, this book presents a comprehensive analysis of heat transport in bulk and nanomaterials based on a kinetic-collective model (KCM). This has become key to understanding the field of thermal transport in semiconductors, and represents an important stride. The book describes how heat transport becomes hydrodynamic at the nanoscale, propagating very much like a viscous fluid and manifesting vorticity and friction-like behavior. It introduces a generalization of Fourier’s law including a hydrodynamic term based on collective behavior in the phonon ensemble. This approach makes it possible to describe in a unifying way recent experiments that had to resort to unphysical assumptions in order to uphold the validity of Fourier’s law, demonstrating that hydrodynamic heat transport is a pervasive type of behavior in semiconductors at reduced scales.
