Aufgrund der steigenden Nachfrage an Lithium werden effektive Verfahren zur Lithium-produktion gesucht. Die größten Lithiumvorkommen sind die Salzseen Südamerikas: Salar de Atacama in Chile und Salar de Uyuni in Bolivien. Im Rahmen dieser Arbeit sollten qualifizierbare Prozessgrundlagen erarbeitet werden. Als Ausgangsmaterial kam eine eingetrocknete Salzmischung des Salar de Uyuni kurz nach der Carnallitabscheidung zum Einsatz. Der Hauptbestandteil war Bischofit neben Lithiumchlorid. Zur Calcinierung wurde ein geeigneter Ofenprozess für die Erzeugung einer größeren Menge Röstgut unter reproduzierbaren Bedingungen entwickelt. Die Extrahierbarkeit von wasserlöslichen Lithiumsalzen aus calciniertem Magnesiumoxid wurde in verschiedenen Laugungsexperimenten untersucht. Mit diesen Grundlagen wurde eine Material- und Energiebilanz für die Erzeugung von 1 t Li2CO3 erstellt und im Zusammenhang mit der Nutzung verschiedener Energiearten diskutiert.

A Soul of a New Machine for our time, a gripping account of invention, commerce, and duplicity in the age of technologyA worldwide race is on to perfect the next engine of economic growth, the advanced lithium-ion battery. It will power the electric car, relieve global warming, and catapult the winner into a new era of economic and political mastery. Can the United States win?Steve LeVine was granted unprecedented access to a secret federal laboratory outside Chicago, where a group of geniuses is trying to solve this next monumental task of physics. But these scientists— almost all foreign born—are not alone. With so much at stake, researchers in Japan, South Korea, and China are in the same pursuit. The drama intensifies when a Silicon Valley start-up licenses the federal laboratory's signature invention with the aim of a blockbuster sale to the world's biggest carmakers.The Powerhouse is a real-time, two-year thrilling account of big invention, big commercialization, and big deception. It exposes the layers of competition and ambition, aspiration and disappointment behind this great turning point in the history of technology.

Lithium has a number of uses but one of the most valuable is a component of high energy-density rechargeable lithium-ion batteries. Because of concerns over carbon dioxide footprint and increasing hydrocarbon fuel cost (reduced supply), lithium may become even more important in large batteries for powering all-electric and hybrid vehicles. Estimates of future lithium demand vary, based on numerous variables. Some of those variables include the potential for recycling, widespread public acceptance of electric vehicles, or the possibility of incentives for converting to lithium-ion-powered engines. This book addresses some of the issues raised by the increased focus on lithium, including the context of the lithium market into which future lithium-based large batteries must fit, the projected effect of electric and hybrid cars on lithium demand, various estimates for future lithium demand, and obstacles to reaching the more optimistic estimates.
