Book Synopsis Electrochemical Modeling of Lithium-Ion Batteries and CNT Biosensors by : Jonathan William Hammond
Download or read book Electrochemical Modeling of Lithium-Ion Batteries and CNT Biosensors written by Jonathan William Hammond and published by . This book was released on 2021 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical systems represent one of the largest markets in technology and design today. Electrochemical systems encompass a wide array of technologies and applications but two of the most common electrochemical systems are batteries and sensors. As these systems advance, there is a growing necessity for highly precise electrochemical modeling, needed for the design, operation and optimization of electrochemical systems. Such models can be divided into two categories: equivalent circuit models (ECMs) and physics-based models. In this study, an examination is made of an ECM for a newly designed electrochemical biosensor and a physics-based model of a lithium-ion NMC532 battery.Biosensor technologies are often slow to use, expensive and are difficult to mass produce, which is problematic in the case of a pandemic as was evidenced early in the COVID-19 outbreak. As such a simple, inexpensive biosensor was developed with the capability of identifying a specific species. The sensor consisted of two silver electrodes printed over a carbon-nanotube (CNT) base which had been coated in a polyethyleneimine layer. The sensor's electric properties were found to decay with time. An ECM was built to track the decay and identify its cause. It was found that oxidation in the CNT layer was likely the cause of decay. It is necessary to measure the entropy of reaction in a battery to determine how much heat will be generated by the cell. Calculating the heat generation is necessary both for safety and to improve the longevity and performance of the cell with cooling systems. Traditional methods of measuring entropy of reaction are slow and require expensive environmental control machinery. As such a physics-based model using a frequency domain method was developed to measure entropy at a significantly faster pace. The model was tested on a custom NMC532 battery with known material parameters to check the model's accuracy. Results from the new model were checked against measurements taken on the same cell using traditional methods. The model validation shows a high degree of accuracy, roughly 50 ℗æV/K, using the new method.

Available in PDF, EPUB and Kindle. Book excerpt: Current imperatives of electrification and decarbonization entail significant improvements in energy density, performance, and cost metrics for battery technology. This has motivated active research into new materials, cell designs, and external controls to ensure safe and efficient operation. Modeling and simulation approaches have a powerful complementary function in this regard, most notably exemplified by the models for Lithium-ion batteries by Newman and co-workers. The overarching theme of this dissertation is thus the development and application of electrochemical modeling approaches at multiple scales in problems relevant to the abovementioned contexts. At the systems level, the development of more intelligent and powerful Battery Management Systems is enabled by fast electrochemical models, which must balance competing considerations of accuracy, computational efficiency, and ease of parameterization. To this end, we report a rigorous and generalized methodology for "upscaling" continuum electrochemical models. This approach, based on the visualization of a battery as Tanks-in-Series, has been demonstrated for both Lithium-ion and more complex Lithium-sulfur batteries. With respect to full models, voltage prediction errors below 20 mV are achieved for high-energy cells in most practical cases. 30 mV errors are achieved for aggressive conditions of high-rate operation at sub-zero ambient temperatures, illustrating their practical utility. This approach results in improved computational speed since each conservation law is replaced by a relatively simple volume-averaged differential or algebraic equation. For examples of large-scale problems, this leads to 10x savings in computation time over fast implementations of conventional models, illustrating competitiveness for real-time applications. In the development of next-generation chemistries, continuum models can serve as a framework for the analysis and interpretation of experimental data, while providing design guidance and helping determine desirable operating regimes. Electrochemical phenomena at different length and time scales are manifested during operation through voltage and temperature signatures, cycle life, and coulombic efficiency. Optimization of cell-level metrics is thus predicated on their correlation with the internal electrochemistry. This entails the integration of electrochemical models at different levels of detail in a computationally efficient and robust manner. To this end, the second half of this dissertation describes our efforts to develop a simulation framework for the modeling of Lithium-metal systems. We first describe a robust computational method to simulate Poisson Nernst Planck (PNP) models for Lithium symmetric cells characterized by thin double layers. This can be leveraged in applications where computational efficiency is of salience, such as cycling simulations and parameterization by coupling kinetic models of interest. This is demonstrated by a systems level method, enabling the quick evaluation of candidate mechanisms appropriately expressed as time-varying rate constants, making it useful for understanding the phenomena underpinning voltage transitions in Lithium symmetric cells. This is followed by a description of a preliminary electrochemical-mechanical model for Li metal interfaces, which is expected to serve as basis for more sophisticated electrochemical-mechanical models for Li metal systems operating under external pressure. We expect these approaches to advance fundamental understanding and design of Li-metal batteries, while creating accessible computational tools to complement experimental studies. Taken together, these contributions are envisaged to advance the knowledge base for model-based design as well as Battery Management Systems, particularly in anticipation of the commercialization of emerging battery chemistries.

This book was released on 2015-11-12 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to review innovative physical multiscale modeling methods which numerically simulate the structure and properties of electrochemical devices for energy storage and conversion. Written by world-class experts in the field, it revisits concepts, methodologies and approaches connecting ab initio with micro-, meso- and macro-scale modeling of components and cells. It also discusses the major scientific challenges of this field, such as that of lithium-ion batteries. This book demonstrates how fuel cells and batteries can be brought together to take advantage of well-established multi-scale physical modeling methodologies to advance research in this area. This book also highlights promising capabilities of such approaches for inexpensive virtual experimentation. In recent years, electrochemical systems such as polymer electrolyte membrane fuel cells, solid oxide fuel cells, water electrolyzers, lithium-ion batteries and supercapacitors have attracted much attention due to their potential for clean energy conversion and as storage devices. This has resulted in tremendous technological progress, such as the development of new electrolytes and new engineering designs of electrode structures. However, these technologies do not yet possess all the necessary characteristics, especially in terms of cost and durability, to compete within the most attractive markets. Physical multiscale modeling approaches bridge the gap between materials’ atomistic and structural properties and the macroscopic behavior of a device. They play a crucial role in optimizing the materials and operation in real-life conditions, thereby enabling enhanced cell performance and durability at a reduced cost. This book provides a valuable resource for researchers, engineers and students interested in physical modelling, numerical simulation, electrochemistry and theoretical chemistry.

Download or read book Electrochemical-thermal Modeling of Lithium-ion Batteries written by Mehrdad Mastali Majdabadi Kohneh and published by . This book was released on 2016 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incorporating lithium-ion (Li-ion) batteries as an energy storage system in electric devices including electric vehicles brings about new challenges. In fact, the design of Li-ion batteries has to be optimized depending on each application specifications to improve the performance and safety of battery operation under each application and at the same time prevent the batteries from quick degradation. As a result, accurate models capable of predicting the behavior of Li-ion batteries under various operating conditions are necessary. Therefore, the main objective of this research is to develop a battery model that includes thermal heating and is suitable for large-sized prismatic cells used in electric vehicles. This works starts with developing a dual-extended Kalman filter based on an equivalent circuit model for the battery. The dual-extended Kalman filter simultaneously estimates the dynamic internal resistance and state of the charge of the battery. However, the estimated parameters are only the fitted values to the experimental data and may be non-physical. In addition, this filter is only valid for the operating conditions that it is validated against via experimental data. To overcome these issues, physics-based electrochemical models for Li-ion batteries are subsequently considered. One drawback of physics-based models is their high computational cost. In this work, two simplified one-dimensional physics-based models capable of predicting the output voltage of coin cells with less than 2.5% maximum error compared to the full-order model are developed. These models reduce the simulation computational time more than one order of magnitude. In addition to computational time, the accuracy of the physico-chemical model parameter estimates is a concern for physics-based models. Therefore, commercial LiFePO4 (LFP) and graphite electrodes are precisely modelled and characterized by fitting experimental data at different charge/discharge rates (C/5 to 5C). The temperature dependency of the kinetic and transport properties of LFP and graphite electrodes is also estimated by fitting experimental data at various temperatures (10 °C, 23 °C, 35 °C, and 45 °C). Since the spatial current and temperature variations in the large-sized prismatic cells are significant, one-dimensional models cannot be used for the modeling of these prismatic cells. In this work, a resistor network methodology is utilized to combine the one-dimensional models into a three-dimensional multi-layer model. The developed model is verified by comparing the simulated temperatures at the surface of the prismatic cell (consist of LFP as the positive and graphite as the negative electrode) to experimental data at different charge/discharge rates (1C, 2C, 3C, and 5C). Using the developed model the effect of tab size and location, and the current collector thickness, on the electrochemical characteristics of large-sized batteries is evaluated. It is shown that transferring tabs from the edges and the same side (common commercial design) to the center and opposite sides of the cell, and extending them as much as possible in width, lowers the non-uniformity variation in electrochemical current generation.
Book Synopsis Water in Lithium-Ion Batteries by : Futoshi Matsumoto
Download or read book Water in Lithium-Ion Batteries written by Futoshi Matsumoto and published by Springer Nature. This book was released on 2022-01-04 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the impact of water content in lithium-ion batteries (LIBs) as well as the reactivity of anodes, cathodes and electrolytes with water and processes that provide water-resistance to materials in LIBs. Water in LIBs which were constructed with anode, cathode and organic electrolyte containing lithium salts can degrade the cell performance and seriously damage the materials present. However, because a small amount of water in cells contributes to the formation of the solid electrolyte interphase, complete removal of water from cells lowers the battery performance and increases costs due to removal of water from the battery materials. This book presents the optimal concentration of water for each battery material along with appropriate removal methods and water-scavengers which were developed recently to establish both high performance and lower costs. Moreover this book describes the development of anodes and cathodes prepared by aqueous process and aqueous LIBs in which aqueous electrolytes containing lithium salts are used as an electrolyte. This book will be useful not only for academic researchers but also for company researchers who deal with LIBs.

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.

Book Synopsis Battery Management Systems by : H.J. Bergveld
Download or read book Battery Management Systems written by H.J. Bergveld and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Battery Management Systems - Design by Modelling describes the design of Battery Management Systems (BMS) with the aid of simulation methods. The basic tasks of BMS are to ensure optimum use of the energy stored in the battery (pack) that powers a portable device and to prevent damage inflicted on the battery (pack). This becomes increasingly important due to the larger power consumption associated with added features to portable devices on the one hand and the demand for longer run times on the other hand. In addition to explaining the general principles of BMS tasks such as charging algorithms and State-of-Charge (SoC) indication methods, the book also covers real-life examples of BMS functionality of practical portable devices such as shavers and cellular phones. Simulations offer the advantage over measurements that less time is needed to gain knowledge of a battery's behaviour in interaction with other parts in a portable device under a wide variety of conditions. This knowledge can be used to improve the design of a BMS, even before a prototype of the portable device has been built. The battery is the central part of a BMS and good simulation models that can be used to improve the BMS design were previously unavailable. Therefore, a large part of the book is devoted to the construction of simulation models for rechargeable batteries. With the aid of several illustrations it is shown that design improvements can indeed be realized with the presented battery models. Examples include an improved charging algorithm that was elaborated in simulations and verified in practice and a new SoC indication system that was developed showing promising results. The contents of Battery Management Systems - Design by Modelling is based on years of research performed at the Philips Research Laboratories. The combination of basic and detailed descriptions of battery behaviour both in chemical and electrical terms makes this book truly multidisciplinary. It can therefore be read both by people with an (electro)chemical and an electrical engineering background.

Download or read book Control Oriented Electrochemical Modeling of Lithium-ion Battery Cells for Applications in EVs, HEVs, and PHEVs written by Sandeep Yayathi and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-ion batteries provide a high energy density and a high power density source for use in many current PHEV and HEV designs. Vehicle energy control strategies are highly dependent on battery performance during various low and high rate operational modes. In this thesis an electrochemical model of a lithium ion cell is developed from the literature. This model will be used in future development of a larger multi-cell battery pack model for use in electric vehicle design and control. This model captures the electrochemical reaction as well as heat and mass transfer within the cell. A physics-based modeling approach is undertaken in this research instead of a parametric modeling technique. This approach will make the effect of battery parameters visible in both the model structure and corresponding system response. It will make the design of control algorithms more robust to system variation. The dynamic effects of the electrochemical reaction and heat and mass transfer within the cell captured by this model are a coupled phenomena, which determine lithium-ion battery performance and life. The cell model is developed using SIMULINK® software from The Mathworks. In addition to development of the cell level model, this thesis will outline the development of an experimental test setup. In order to validate the model, it is necessary to collect data from actual lithium ion cells under various charge and discharge profiles. The experimental logistical and budgetary considerations are also taken into account. The final configuration of the lab equipment is robust enough to handle testing of single lithium-ion cells from low capacity to high capacity as well as entire battery pack modules for the development of vehicle level power management. The automation and data collection for this test setup is accomplished with LabVIEW® from National Instruments.
