Taschenbuch. Zustand: Neu. Neuware -This brief deals with various forms of supercapacitors starting from traditional carbon based supercapacitors to advanced next generation hybrid supercapacitors. The primary focus is to investigate the successive evolution in the core components of a typical supercapacitor which will bring significant observations regarding their feasibility and overall impact on the charge storage capacity so as to reach at par with the current battery technology. The authors present a critical review of the current collectors, electrode materials and electrolytic components which have distinctive impact on both the power and energy density of a supercapacitor. Emerging trends in the fabrication of hybrid supercapacitor technology bring together the exceptional power density of a double layer capacitor and energy density of a rechargeable battery, which promises a brighter future for the electrical energy storage system.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Rapid growth in the research and development of clean energy storage techniques has yielded a significant number of electrochemically active compounds/materials possessing enormous potential to facilitate the fabrication of next generation devices such as the supercapacitor. This Brief describes recent progress in the field of metal-ion based hybrid electrical energy storage devices, with emphasis on the effect of different metal ions and other constituent components on the overall electrochemical performance of battery-supercapacitor hybrids (BSHs). Although significant efforts have been made to create an effective electrical energy storage system that would have the energy density of a battery and the power density of a supercapacitor, persistent challenges still lie in combining these two altogether different systems to form a cost-effective and safe storage device. Detailed comparisons of output performance and longevity (in terms of cyclic stability) are provided, including device fabrication cost and safety.Of the several proposed schematics/prototypes, hybrid supercapacitors, with both carbon-based EDLC electrode and pure faradic (battery type) electrode can work in tandem to yield high energy densities with little degradation in specific power. As a promising electric energy storage device, supercapacitors address several critical issues in various fields of applications from miniaturized electronic devices and wearable electronics to power hungry heavy automobiles. Depending on the electrode configuration and other controlling parameters, these BSHs can have contrasting performance statistics. Metal ion BSHs such as Li+, Na+, Mg+2, Zn+2 etc., acid-alkaline BSHs, and redox electrolyte based BSHs all represent recent approaches, with BSHs based on metal ions, particularly Lithium, of particular interest because of the extreme popularity of Li-ion based batteries. This book is writtenfor a broad readership of graduate students and academic and industrial researchers who are concerned with the growth and development of sustainable energy systems where efficient and cost-effective storage is key.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 120 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The depletion of fossil fuels from the earth¿s crust, and related environmental issues such as climate change, demand that we search for alternative energy resources to achieve some formof sustainable future. In this regard, much scientific research has been devoted to technologies such as solar cells, wind turbines, fuel cells etc. Among them fuel cells attract much attention because of their versatility and efficiency. In fuel cells, different fuels such as hydrogen, CO2, alcohols, acids, methane, oxygen/air, etc. are used as the fuel, and catalysts are employed to produce a chemical reaction for generating electricity. Hence, it is very important to produce these fuels in an efficient, eco-friendly, and cost effective manner. The electrochemical splitting of water is an environmentally friendly process to produce hydrogen (the greener fuel used in fuel cells), but the efficiencies of these hydrogen evolution reactions (cathodic half reaction) are strongly dependent on the anodic half reaction (oxygen evolution reaction), i.e., the better the anodic half, the better will be the cathodic reaction. Further, this oxygen evolution reaction depends on the types of activeelectrocatalysts used. Though many more synthetic approaches have been explored and different electrocatalysts developed, oxide and hydroxide-based nanomaterials and composites (with graphene, carbon nanotubes etc.) show better performance. This may be due to the availability of more catalytic surface area and electro active centers to carry out the catalysis process.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 104 pp. Englisch.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book covers the recent development of metal oxides, hydroxides and their carbon composites for electrochemical oxidation of water in the production of hydrogen and oxygen as fuels. It includes a detailed discussion on synthesis methodologies for the metal oxides/hydroxides, structural/morphological characterizations, and the key parameters (Tafel plot, Turnover frequency, Faradic efficiency, overpotential, long cycle life etc.) needed to evaluate the electrocatalytic activity of the materials. Additionally, the mechanism behind the electro oxidation process is presented. Readers will find a comprehensive source on the close correlation between metal oxides, hydroxides, composites, and their properties and importance in the generation of hydrogen and oxygen from water.The depletion of fossil fuels from the earth's crust, and related environmental issues such as climate change, demand that we search for alternative energy resources to achieve some formof sustainable future.
