Nanomaterials for Electrochemical Energy Storage
Nanomaterials for Electrochemical Energy Storage: Challenges and Opportunities, Volume Nineteen provides an objective, realistic overview on the use of nanomaterials for various rechargeable electrochemical energy storage systems. It delivers a clear message on opportunities and critical aspects for the application of nanomaterials in currently available commercial devices (i.e., lithium-ion, supercapacitors, lithium-ion capacitors) and in the most promising battery technologies (e.g., lithium-sulphur, sodium-ion, metal-air, multivalent-ion batteries, dual-ion). In addition, it covers the use of nanomaterials on two of the most promising research pathways, specifically solid electrolytes and...
Electrochemical Capacitors
Electrochemical capacitors are most important for the development of future energy storage systems and sustainable power sources. New superior hybrid supercapacitors are based on binary and ternary thin film nanocomposites involving carbon, metal oxides and polymeric materials. The synthesis of materials and fabrication of electrodes for supercapacitor applications is discussed in detail. The book also presents the fundamental theory and a thorough literature review of supercapacitors. Energy Storage, Electrochemical Capacitors, Nanocomposites, Hybrid Supercapacitors, Carbon/Metal Oxide Composites, Metal Oxides/Hydroxides Composites, Polymer Type Capacitors, Nanoscience, Hydrothermal Synthesis, Graphene-based Composites, Ultrasonic Assisted Synthesis
Semiconductor Nanodevices
Semiconductor Nanodevices: Physics, Technology and Applications explores recent advances in the field. The behaviour of these devices is controlled by regions of nanoscale dimensions which typically determine the local density of electronic states and lead to the observation of a range of quantum effects with significant potential for exploitation. The book opens with an introduction describing the development of this research field over the past few decades which contrasts quantum-controlled devices to conventional nanoscale electronic devices where an emphasis has often been placed on minimising quantum effects. This introduction is followed by seven chapters describing electrical nanodevi...
Energy Landscapes of Nanoscale Systems
Energy Landscapes of Nanoscale Systems provides a snapshot of the state-of-the-art in energy landscapes theory and applications. The book's chapters reflect diversity and knowledge transfer that is a key strength of the energy landscape approach. To reflect the breadth of this field, contributions include applications for clusters, biomolecules, crystal structure prediction and glassy materials. Chapters highlighting new methodologies, especially enhanced sampling techniques are included. In particular, the development and application of global optimization for structure prediction, methods for treating broken ergodicity on multifunnel landscapes, and treatment of rare event dynamics that re...
Microscopy and Microanalysis for Lithium-Ion Batteries
The past three decades have witnessed the great success of lithium-ion batteries, especially in the areas of 3C products, electrical vehicles, and smart grid applications. However, further optimization of the energy/power density, coulombic efficiency, cycle life, charge speed, and environmental adaptability are still needed. To address these issues, a thorough understanding of the reaction inside a battery or dynamic evolution of each component is required. Microscopy and Microanalysis for Lithium-Ion Batteries discusses advanced analytical techniques that offer the capability of resolving the structure and chemistry at an atomic resolution to further drive lithium-ion battery research and development. Provides comprehensive techniques that probe the fundamentals of Li-ion batteries Covers the basic principles of the techniques involved as well as its application in battery research Describes details of experimental setups and procedure for successful experiments This reference is aimed at researchers, engineers, and scientists studying lithium-ion batteries including chemical, materials, and electrical engineers, as well as chemists and physicists.
Italian thrash metal militia
Siamo agli albori degli anni Ottanta, quando un gruppetto di metallari inglesi, brutti, sporchi e cattivi, pubblica un paio di album destinati a cambiare la storia del metal. La semina dei Venom attecchisce in breve tempo negli Stati Uniti con Metallica e Slayer, ma sarà l’Europa – insieme al Brasile – a offrire la declinazione più brutale e violenta per sonorità, testi e immagine proposti. L’Italia si inserisce alla perfezione nel contesto europeo dominato da gruppi tedeschi e scandinavi, fornendo un contributo fondamentale e universalmente riconosciuto allo sviluppo in senso estremo del metal di quegli anni. Autentici capofila del movimento sono i milanesi Bulldozer, cui non a c...
Impedanzbasierte Spannungsprädiktion von Lithium-Ionen-Batterien
Diese Arbeit präsentiert ein physikalisch motiviertes Modell, welches die Zellspannung einer Lithium-Ionen-Batterie auf Basis der Zellimpedanz vorhersagt. Das Modell wurde an einer kommerziellen Pouchzelle parametriert und validiert. In einer umfassenden Simulationsstudie wird der Einfluss der Elektrodenmikrostruktur auf die Energie- und Leistungsdichte der Zelle quantifiziert. Darüber hinaus wird eine Routine zur Entwicklung anwendungsspezifischer Zelldesigns vorgestellt. - This work presents a physically motivated model that predicts the cell voltage of a lithium-ion-battery based on its impedance. The model was parameterized and validated on a commercial pouch cell. In a comprehensive simulation study, the influence of the electrode microstructure parameters on the energy and power density is quantified. Furthermore, a routine for the development of application-specific cell designs is developed.
Charakterisierung und Modellierung der waessrigen Lithium-Luft Batterie
To estimate the reachable specific energy and power of aqueous Li-air batteries, a physical based model was developed, which for the first time includes the microstructure of Li-air cells. Parameters like solid/liquid interface resistances were quantified with help of a newly developed setup. Simulations based on the developed model revealed that even conservative estimations promise an increase in the specific energy by at least a factor of two compared to present Li-ion batteries.
Na-ion Batteries
This book covers both the fundamental and applied aspects of advanced Na-ion batteries (NIB) which have proven to be a potential challenger to Li-ion batteries. Both the chemistry and design of positive and negative electrode materials are examined. In NIB, the electrolyte is also a crucial part of the batteries and the recent research, showing a possible alternative to classical electrolytes – with the development of ionic liquid-based electrolytes – is also explored. Cycling performance in NIB is also strongly associated with the quality of the electrode-electrolyte interface, where electrolyte degradation takes place; thus, Na-ion Batteries details the recent achievements in furthering knowledge of this interface. Finally, as the ultimate goal is commercialization of this new electrical storage technology, the last chapters are dedicated to the industrial point of view, given by two startup companies, who developed two different NIB chemistries for complementary applications and markets.
