Batteries, 2 Volumes
Dieses ausführliche zweibändige Handbuch, Teil der Encyclopedia of Electrochemistry, bietet einen aktuellen und umfassenden Einblick in heutige Batterietechnologien. Behandelt werden Technologien, die über das Potenzial für weitere Energie- und Leistungsdichte verfügen. Die Inhalte stammen von renommierten internationalen Experten des Fachgebiets. - Batterien sind aus dem heutigen Alltag nicht mehr wegzudenken. Sie liefern als elektrochemisch gespeicherte Energie Strom für Fahrzeuge, Flugzeuge, elektronische Geräte und intelligente Stromnetze. Ausführliche Informationen gibt es zu etablierten Batterietechnologien wie Blei-Säure- und Lithium-Ionen-Batterien. Untersucht werden auch aktuelle Entwicklungen neuer Technologien, darunter Lithium-Schwefel- und Lithium-Sauerstoff-Batterien, Natrium-Ionen-Batterien und vollständig organische Batterien. - Das Handbuch richtet sich an Elektrochemiker, Physikochemiker und Materialwissenschaftler. Das zugängliche Kompendium unterzieht die wichtigsten Batterietechnologien einer eingehenden Überprüfung und untersucht die Technologie der Zukunft.

Age of Auto Electric
The electric vehicle revival reflects negotiations between public policy, which promotes clean, fuel-efficient vehicles, and the auto industry, which promotes high-performance vehicles. Electric cars were once as numerous as internal combustion engine cars before all but vanishing from American roads around World War I. Now, we are in the midst of an electric vehicle revival, and the goal for a sustainable car seems to be within reach. In Age of Auto Electric, Matthew N. Eisler shows that the halting development of the electric car in the intervening decades was a consequence of tensions between environmental, energy, and economic policy imperatives that informed a protracted reappraisal of ...
Physically based Impedance Modelling of Lithium-Ion Cells
In this book, a new procedure to analyze lithium-ion cells is introduced. The cells are disassembled to analyze their components in experimental cell housings. Then, Electrochemical Impedance Spectroscopy, time domain measurements and the Distribution function of Relaxation Times are applied to obtain a deep understanding of the relevant loss processes. This procedure yields a notable surplus of information about the electrode contributions to the overall internal resistance of the cell.
Advances in Speech Coding
Speech coding has been an ongoing area of research for several decades, yet the level of activity and interest in this area has expanded dramatically in the last several years. Important advances in algorithmic techniques for speech coding have recently emerged and excellent progress has been achieved in producing high quality speech at bit rates as low as 4.8 kb/s. Although the complexity of the newer more sophisticated algorithms greatly exceeds that of older methods (such as ADPCM), today's powerful programmable signal processor chips allow rapid technology transfer from research to product development and permit many new cost-effective applications of speech coding. In particular, low bit rate voice technology is converging with the needs of the rapidly evolving digital telecom munication networks. The IEEE Workshop on Speech Coding for Telecommunications was held in Vancouver, British Columbia, Canada, from September 5 to 8, 1989. The objective of the workshop was to provide a forum for discussion of recent developments and future directions in speech coding. The workshop attracted over 130 researchers from several countries and its technical program included 51 papers.
