This book provides comprehensive coverage of Lithium (Li) metal anodes for rechargeable batteries. Li is an ideal anode material for rechargeable batteries due to its extremely high theoretical specific capacity (3860 mAh g-1), low density (0.59 g cm-3), and the lowest negative electrochemical potential (−3.040 V vs. standard hydrogenelectrodes). Unfortunately, uncontrollable dendritic Li growth and limited Coulombic efficiency during Li deposition/stripping inherent in these batteries have prevented their practical applications over the past 40 years. With the emergence of post Liion batteries, safe and efficient operation of Li metal anodes has become an enabling technology which may determine the fate of several promising candidates for the next generation energy storage systems, including rechargeable Li-air batteries, Li-S batteries, and Li metal batteries which utilize intercalation compounds as cathodes.In this work, various factors that affect the morphology and Coulombic efficiency of Li anodes are analyzed. The authors also present the technologies utilized to characterize the morphology of Li deposition and the results obtained by modeling of Li dendrite growth. Finally, recent developments, especially the new approaches that enable safe and efficient operation of Li metal anodes at high current densities are reviewed. The urgent need and perspectives in this field are also discussed. The fundamental understanding and approaches presented in this work will be critical for the applicationof Li metal anodes. The general principles and approaches can also be used in other metal electrodes and general electrochemical deposition of metal films.

This book provides a systematic and standardized approach based on the authors’ over 30 years of research experience with weight function methods, as well as the relevant literature. Fracture mechanics has become an indispensable tool for the design and safe operation of damage-tolerant structures in many important technical areas. The stress intensity factor—the characterizing parameter of the crack tip field—is the foundation of fracture mechanics analysis. The weight function method is a powerful technique for determining stress intensity factors and crack opening displacements for complex load conditions, with remarkable computational efficiency and high accuracy.The book presents the theoretical background of the weight function methods, together with a wealth of analytical weight functions and stress intensity factors for two- and three-dimensional crack geometries; many of these have been incorporated into national, international standards and industrial codes of practice. The accuracy of the results is rigorously verified, and various sample applications are provided. Accordingly, the book offers an ideal reference source for graduate students, researchers, and engineers whose work involves fracture and fatigue of materials and structures, who need not only stress intensity factors themselves but also efficient and reliable tools for obtaining them.

Dieses Buch bietet einen systematischen und standardisierten Ansatz, der auf der über 30-jährigen Forschungserfahrung der Autoren mit Gewichtsfunktionsmethoden sowie auf der einschlägigen Literatur basiert. Die Bruchmechanik ist in vielen wichtigen technischen Bereichen zu einem unverzichtbaren Werkzeug für die Auslegung und den sicheren Betrieb von schadenstoleranten Strukturen geworden. Der Spannungsintensitätsfaktor - der charakterisierende Parameter des Rissspitzenfeldes - ist die Grundlage der bruchmechanischen Analyse. Die Gewichtsfunktionsmethode ist ein leistungsfähiges Verfahren zur Bestimmung von Spannungsintensitätsfaktoren und Rissöffnungsverschiebungen für komplexe Belastungszustände mit bemerkenswerter Berechnungseffizienz und hoher Genauigkeit.Das Buch stellt den theoretischen Hintergrund der Gewichtsfunktionsmethoden sowie eine Fülle von analytischen Gewichtsfunktionen und Spannungsintensitätsfaktoren für zwei- und dreidimensionale Rissgeometrien vor, von denen viele in nationale und internationale Normen und industrielle Regelwerke eingeflossen sind. Die Genauigkeit der Ergebnisse wird genauestens überprüft, und es werden verschiedene Anwendungsbeispiele gegeben. Das Buch ist somit ein ideales Nachschlagewerk für Studenten, Forscher und Ingenieure, die sich mit dem Bruch und der Ermüdung von Werkstoffen und Strukturen befassen und nicht nur die Spannungsintensitätsfaktoren selbst, sondern auch effiziente und zuverlässige Werkzeuge zu deren Ermittlung benötigen.
