This book was released on 2020-05-11 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Redox-Flow batteries can play a crucial role in the future electricity supply in order to balance the time lag between the generation of electrical energy from photovoltaics or wind power and the demand for electrical energy. However, to deploy the technology on a large scale, significant cost reductions are required. A thorough knowledge of the reactions and processes taking place within a redox-flow battery is very helpful for this task and this knowledge can be significantly improved by using a suitable mathematical model to describe the processes in a single cell of a redox-flow battery. Nevertheless, this requires a valid model that has been compared with experimental data and that can reproduce these data plausibly and validly. In this thesis, the validation of a two-dimensional model for the description of potential and current density distributions in the porous electrodes of a vanadium redox-flow battery is presented, taking into account effects of kinetics and mass transport. Newly developed potential probes are used for in-situ measurement of solid and liquid phase potentials within a single cell of a vanadium redox-flow battery. The description of the measured cell voltage and potential probe signals by the model reveals a good congruence between the model and the experimental data, so the model can be regarded as valid. Additional suggestions for improvements of the model and the implementation of further models describing membrane crossover effects or electrolyte properties are given.

Book Synopsis Model-based Design and Optimization of Vanadium Redox Flow Batteries by : Sebastian König
Download or read book Model-based Design and Optimization of Vanadium Redox Flow Batteries written by Sebastian König and published by Cuvillier Verlag. This book was released on 2017-09-13 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, a holistic approach is used to develop a multi-physical model of the Vanadium Redox Flow Battery on a system level. The model is validated with experimental data from three flow battery manufacturers and is then deployed in an extensive parameter study for designing a flow battery cell. Using finite element analysis (FEA), twenty-four different cell designs are derived, which vary in electrode area and the design of the electrolyte inlet and outlet supply channels. The performance of the designs is then simulated in a single-stack and a three-stack string system. The presented model is also deployed in a flow rate optimization study. Here, a novel strategy involving the model-based optimization of operation-points defined by state-of-charge and charging or discharging current is presented and compared to conventional flow rate control strategies. Finally, a stack voltage controller is introduced, which prevents the violation of cell voltage limits as long as the pump capacity is not fully utilized.

This book was released on 2016-12-30 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines issues related to massive integration of electric and plug-in hybrid electric vehicles into power grids. Electricity is becoming the preferred energy vector for the next new generation of road vehicles. It is widely acknowledged that road vehicles based on full electric or hybrid drives can mitigate problems related to fossil fuel dependence. This book explains the emerging and understanding of storage systems for electric and plug-in hybrid vehicles. The recharging stations for these types of vehicles might represent a great advantage for the electric grid by facilitating integration of renewable and distributed energy production. This book presents a broad review from analyzing current literature to on-going research projects about the new power technologies related to the various charging architectures for electric and plug-in hybrid vehicles. Specifically focusing on DC fast charging operations, as well as, grid-connected power converters and the full range of energy storage systems. These key components are analyzed for distributed generation and charging system integration into micro-grids. The authors demonstrate that these storage systems represent effective interfaces for the control and management of renewable and sustainable distributed energy resources. New standards and applications are emerging from micro-grid pilot projects around the world and case studies demonstrate the convenience and feasibility of distributed energy management.

Download or read book Energy Storage written by Alfred Rufer and published by CRC Press. This book was released on 2017-10-31 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will provide the technical community with an overview of the development of new solutions and products that address key topics, including electric/hybrid vehicles, ultrafast battery charging, smart grids, renewable energy (e.g., solar and wind), peak shaving, and reduction of energy consumption. The needs for storage discussed are within the context of changes between the centralized power generation of today and the distributed utility of tomorrow, including the integration of renewable energy sources. Throughout the book, methods for quantitative and qualitative comparison of energy storage means are presented through their energy capacity as well as through their power capability for different applications. The definitions and symbols for energy density and power density are given and relate to the volume and weight of a given system or component. A relatively underdeveloped concept that is crucial to this text is known as the theory of Ragone plots. This theory makes possible the evaluation of the real amount of energy that can possibly release out of a given system, with respect to the level of power dependency chosen for the discharge process. From systems using electrochemical transformations, to classical battery energy storage elements and so-called flow batteries, to fuel cells and hydrogen storage, this book further investigates storage systems based on physical principles (e.g., gravitational potential forces, air compression, and rotational kinetic energy). This text also examines purely electrical systems such as superconductive magnets and capacitors. Another subject of analysis is the presentation of power electronic circuits and architectures that are needed for continuously controllable power flow to and from different storage means. For all systems described, the elementary principles of operation are given as well as the relationships for the quantified storage of energy. Finally, Energy Storage: Systems and Components contains multiple international case studies and a rich set of exercises that serve both students and practicing engineers.

Download or read book Numerical Modeling of an All Vanadium Redox Flow Battery written by and published by . This book was released on 2014 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a capability to simulate reduction-oxidation (redox) flow batteries in the Sierra Multi-Mechanics code base. Specifically, we focus on all-vanadium redox flow batteries; however, the capability is general in implementation and could be adopted to other chemistries. The electrochemical and porous flow models follow those developed in the recent publication by [28]. We review the model implemented in this work and its assumptions, and we show several verification cases including a binary electrolyte, and a battery half-cell. Then, we compare our model implementation with the experimental results shown in [28], with good agreement seen. Next, a sensitivity study is conducted for the major model parameters, which is beneficial in targeting specific features of the redox flow cell for improvement. Lastly, we simulate a three-dimensional version of the flow cell to determine the impact of plenum channels on the performance of the cell. Such channels are frequently seen in experimental designs where the current collector plates are borrowed from fuel cell designs. These designs use a serpentine channel etched into a solid collector plate.

Book Synopsis Physicochemical Hydrodynamics by : Ronald F. Probstein
Download or read book Physicochemical Hydrodynamics written by Ronald F. Probstein and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physicochemical Hydrodynamics: An Introduction aims to provide an introduction to physicochemical hydrodynamics (PCH), which deals with the interaction between fluid flow and physical, chemical, and biochemical processes. PCH has applications in many areas of science and technology and is a rapidly expanding field. Emphasis of this book is on rational theory and its consequences, with the purpose of showing the underlying unity of PCH, in which diverse phenomena can be described in physically and mathematically similar ways. The magic of this unity is shown in the similar manner in which solutes concentrate in a flow containing chemically reacting surfaces, reverse osmosis membranes, and electrodialysis membranes or the similarity of particle motions in sedimentation, centrifugation, ultrafiltration, and electrophoresis. Problems are included at the end of each chapter and are ordered following the sequence in which the material is set out. The questions range in difficulty, with most requiring an analytic development, but with some asking only for a descriptive answer. All problems are intended to illustrate the ideas presented, though often the solution goes beyond the explicit discussion in the book, with the answer constituting a generalization or extension of the text material. This book is an essential source of information for students majoring in the field of PCH.

Book Synopsis Lithium-ion Batteries by : Perla B. Balbuena
Download or read book Lithium-ion Batteries written by Perla B. Balbuena and published by World Scientific. This book was released on 2004 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book focuses on the mechanisms of formation of a solid-electrolyte interphase (SEI) on the electrode surfaces of lithium-ion batteries. The SEI film is due to electromechanical reduction of species present in the electrolyte. It is widely recognized that the presence of the film plays an essential role in the battery performance, and its very nature can determine an extended (or shorter) life for the battery. In spite of the numerous related research efforts, details on the stability of the SEI composition and its influence on the battery capacity are still controversial. This book carefully analyzes and discusses the most recent findings and advances on this topic.
