This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: With massive commercial success of lithium ion batteries, the ability to operate at and above 70 °C still a crucial issue and a safety concern to combat ever-increasing global warming and to extend applications beyond portable electronics. Among various components of battery, anode and electrolyte and the passivation layer formed between them is crucial towards the development of Li-ion batteries for extendable temperature range. In this regard, room temperature ionic liquids (RTILs) have the capability to tackle thermal stability issues of lithium ion batteries but their poor compatibility with traditional graphite anodes limits their practical application. Towards addressing this issue, we explore the feasibility of engineered three-dimensional Si (3D Si) anodes inconjunction with modified RTIL as an electrolyte and their electrochemical performance up to 150 °C. Detailed electrochemical studies such as electrochemical stability, ionic conductivity, specific capacity, rate capability, and coulombic efficiency reveal that 3D Si anode and RTIL combinations are thermally stable for high temperature rechargeable battery applications. Further, silicon electrode in full cell configuration has been demonstrated in associated with LiFePO4/C cathode to develop next generation Li-ion batteries with enhanced safety and thermal stability. Interaction between electrode and electrolyte has been evaluated by conducting X-ray photoelectron spectroscopy and electron microscopy studies at various electrochemical conditions.
Book Synopsis A Multi-faceted Approach Towards Improving the Performance of Silicon Electrodes for Next-generation Lithium-ion Batteries by : Michael Melnyk
Download or read book A Multi-faceted Approach Towards Improving the Performance of Silicon Electrodes for Next-generation Lithium-ion Batteries written by Michael Melnyk and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although lithium-ion battery technology has been the catalyst in enabling modern electric vehicle, mobile device, and large-scale energy storage technology, the increasing power demands by end-users has motivated research in developing the next-generation of lithium-ion batteries. This next generation of batteries will need to achieve higher energy and power densities, while remaining chemically stable. Silicon-based active material has been proposed as a solution in achieving superior battery performance, as it can offer a lithium storage capacity (4200 mAh/g) tenfold higher than the carbonaceous electrodes employed in commercial Li-ion cells, while also offering superior safety characteristics. Unfortunately, the higher lithium storage capacity translates into an immense volume expansion (300 - 400%) upon lithiation, and thus the mechanical integrity and electrochemical performance of the electrodes are very unstable. Within the past decade, the performance of Si-based electrodes has been greatly improved as active material morphologies, polymer binders, electrolyte additives, and theoretical models have provided solutions in alleviating the stresses and strains generated during Si lithiation/delithiation. A multi-faceted solution pathway is enacted in this research to develop a Si-based electrode that can achieve cycling performance relevant to industrial application, while also offering insight on the influence of several aspects of the Si-based electrode design on cycling performance. From this investigation, a Si-based electrode has been developed with carbon-coated silicon monoxide active material and polyacrylic acid polymer binder, both of which offer several complimentary attributes that enable a moderately stable cycling performance at high active mass loading while offering a gravimetric and areal lithium capacity magnitude relevant to industrial applications. Although much work lies ahead in further improving the capacity retention of the Si-based electrodes reported in this thesis, this work presents an economical platform for future work on the topic.

Book Synopsis Silicon Inverse Opal-based Materials as Electrodes for Lithium-ion Batteries by : Alexei Esmanski
Download or read book Silicon Inverse Opal-based Materials as Electrodes for Lithium-ion Batteries written by Alexei Esmanski and published by . This book was released on 2008 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional macroporous structures ('opals' and 'inverse opals') can be produced by colloidal crystal templating, one of the most intensively studied areas in materials science today. There are several potential advantages of lithium-ion battery electrodes based on inverse opal structures. High electrode surface, easier electrolyte access to the bulk of electrode and reduced lithium diffusion lengths allow higher discharge rates. Highly open structures provide for better mechanical stability to volume swings during cycling.Silicon is one of the most promising anode materials for lithium-ion batteries. Its theoretical capacity exceeds capacities of all other materials besides metallic lithium. Silicon is abundant, cheap, and its use would allow for incorporation of microbattery production into the semiconductor manufacturing. Performance of silicon is restricted mainly by large volume changes during cycling.The objective of this work was to investigate how the inverse opal structures influence the performance of silicon electrodes. Several types of silicon-based inverse opal films were synthesised, and their electrochemical performance was studied.Amorphous silicon inverse opals were fabricated via chemical vapour deposition and characterised by various techniques. Galvanostatic cycling of these materials confirmed the feasibility of the approach taken, since the electrodes demonstrated high capacities and decent capacity retentions. The rate performance of amorphous silicon inverse opals was unsatisfactory due to low conductivity of silicon. The conductivity of silicon inverse opals was improved by crystallisation. Nanocrystalline silicon inverse opals demonstrated much better rate capabilities, but the capacities faded to zero after several cycles.Silicon-carbon composite inverse opal materials were synthesised by depositing a thin layer of carbon via pyrolysis of a sucrose-based precursor onto the silicon inverse opals in an attempt to further increase conductivity and achieve mechanical stabilisation of the structures. The amount of carbon deposited proved to be insufficient to stabilise the structures, and silicon-carbon composites demonstrated unsatisfactory electrochemical behaviour.Carbon inverse opals were coated with amorphous silicon producing another type of macroporous composites. These electrodes demonstrated significant improvement both in capacity retentions and in rate capabilities. The inner carbon matrix not only increased the material conductivity, but also resulted in lower silicon pulverisation during cycling.

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.

This book was released on 2017 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: To further improve the stability and capacity of the Si-based anode materials, the yolk-shell carbon-coated Si nanoparticles, which contain a void space between the yolk and shell, were studied through in situ lithiation and theoretical modeling, as discussed in Chapter 6. The geometrical dimension-dependent fracture of the nanoparticles was revealed from the experimental studies. A mechanics-based theoretical model was proposed to calculate the stress states in the carbon shell upon full lithiation. A design guideline was provided to maintain the structural integrity and maximize the capacity by optimizing the geometrical dimensions of the yolk-shell carbon-coated Si nanoparticles. Apart from voiding the fracture, interfacial stability between electrodes and cooper (Cu) current collector is also important for improving the performance of the Si-based electrode materials. In Chapter 7, the Si-coated Cu nanowires were synthesized though hydrothermal method and magnetron sputtering technique. The lithium nanostructures formed on the surface of Si shell during delithiation. The bulk lithium nanostructures reacted with the delithiated Si shell to form LixSi, inducing the fracture of the Si shell. However, the Si shell adhered well with the Cu core, indicating a stable cycling performance. These results showed the potential application of the Si-coated Cu nanowire structured anode materials for lithium ion batteries. Through the comprehensive studies of the core-shell nanostructured electrode materials, the lithiation/delithiation and fracture mechanisms of the high-capacity core-shell nanostructured electrode materials were analyzed. The experimental and theoretical approaches should be beneficial for the study of other electrode materials. The optimal design guidelines proposed in this thesis should be of great value for the design of the core-shell structured electrode materials with supreme structural integrity and high capacity for lithium ion batteries.

Download or read book Development of Silicon-based Anodes and In-situ Characterization Techniques for Lithium Ion Batteries written by Jinho Yang and published by . This book was released on 2014 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of lithium ion batteries (LIBs) with higher capacity has been booming worldwide, as growing concerns about environmental issues and increasing petroleum costs. The demands for the LIBs include high energy and power densities, and better cyclic stability in order to meet a wide range of applications, such as portable devices and electric vehicles. Silicon has recently been explored as a promising anode material due to its low discharge potential (0.4 V) and high specific capacity (4200 mAh gsuper-1/super). The capacity of silicon potentially exceeds more than 10 times of the conventional graphite anode (372 mAh gsuper-1/super). However, the silicon anode experiences huge volume expansion (400%) and contraction during electrochemical cycles, resulting in pulverization and disintegration of the active material. For the improvement of the battery performance, understanding of the failure mechanism associated with the stress evolution during cycling is critical. This study aims (1) to develop high performance anode materials and (2) to analyze the mechanism of the capacity fading using a novel in-situ characterization technique in order to optimize the electrode design for better operation of the battery. The silicon nitride thin film anodes were investigated for the improvement of cycling performance. In addition, the rate performance was enhanced by controlling the parameters in film deposition. Si-based thin films undergo large stresses induced by the volume changes, which results in material degradation and capacity fading. Hence, the in-situ measurement of the electrochemical processes is critical to clarify how the electrode degrades with time under cycling. For the in-situ measurement, a white light interferometry (WLI) and laser vibrometer were used to gather quantitative data. Amorphous silicon (italica

Book Synopsis Effect of Design Parameters and Intercalation Induced Stresses in Lithium Ion Batteries by : Sumitava De
Download or read book Effect of Design Parameters and Intercalation Induced Stresses in Lithium Ion Batteries written by Sumitava De and published by . This book was released on 2014 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical power sources, especially lithium ion batteries have become major players in various industrial sectors, with applications ranging from low power/energy demands to high power/energy requirements. But there are some significant issues existing for lithium ion systems which include underutilization, stress-induced material damage, capacity fade, and the potential for thermal runaway. Therefore, better design, operation and control of lithium ion batteries are essential to meet the growing demands of energy storage. Physics based modeling and simulation methods provide the best and most accurate approach for addressing such issues for lithium ion battery systems. This work tries to understand and address some of these issues, by development of physics based models and efficient simulation of such models for battery design and real time control purposes. This thesis will introduce a model-based procedure for simultaneous optimization of design parameters for porous electrodes that are commonly used in lithium ion systems. The approach simultaneously optimizes the battery design variables of electrode porosities and thickness for maximization of the energy drawn for an applied current, cut-off voltage, and total time of discharge. The results show reasonable improvement in the specific energy drawn from the lithium ion battery when the design parameters are simultaneously optimized. The second part of this dissertation will develop a 2-dimensional transient numerical model used to simulate the electrochemical lithium insertion in a silicon nanowire (Si NW) electrode. The model geometry is a cylindrical Si NW electrode anchored to a copper current collector (Cu CC) substrate. The model solves for diffusion of lithium in Si NW, stress generation in the Si NW due to chemical and elastic strain, stress generation in the Cu CC due to elastic strain, and volume expansion in the Si NW and Cu CC geometries. The evolution of stress components, i.e., radial, axial and tangential stresses in different regions in the Si NW are studied in details. Lithium-ion batteries are typically modeled using porous electrode theory coupled with various transport and reaction mechanisms with an appropriate discretization or approximation for the solid phase diffusion within the electrode particle. One of the major difficulties in simulating Li-ion battery models is the need for simulating solid-phase diffusion in the second radial dimension r within the particle. It increases the complexity of the model as well as the computation time/cost to a great extent. This is particularly true for the inclusion of pressure induced diffusion inside particles experiencing volume change. Therefore, to address such issues, part of the work will involve development of efficient methods for particle/solid phase reformulation - (1) parabolic profile approach and (2) a mixed order finite difference method. These models will be used for approximating/representing solid-phase concentration variations within the active material. Efficiency in simulation of particle level models can be of great advantage when these are coupled with macro-homogenous cell sandwich level battery models.
