Book excerpt: In this research work, nanometer-scale alloy particles composed of Au with Fe, Pd and Pt metals respectively were synthesized and used as coating material with the objective to improve the microstructure and catalytic activities of pristine LiMn2O4. These bimetallic nanoparticles were selected based on their ability to provide high electronic conductivity where needed, maintain a thermodynamically stable interface with LiMn2)4, and their potential to act as a chemical catalyst for electrochemical reactions at the nanoscale. Nanoalloys were coated onto the spinel LiMn2O4 via a co-precipitation calcination method and its effect on the conductivity, stability and high rate performances of LiMn2O4 was investigated. The pristine LiMn2O4 and modified cathode materials were examined using a combination of spectroscopic and microscopic techniques along with in detail galvanostatic charge-discharge tests. Microscopic results revealed that the novel nana-alloy composite cathode materials had high phase purity, well crystallized particles and more regular morphological structures with narrow size distributions.

Book Synopsis Development of Pseudocapacitive Properties in Nanostructured LiMn2O4 as a Fast Charging Cathode for Lithium Ion Batteries by : Benjamin Kalman Lesel
Download or read book Development of Pseudocapacitive Properties in Nanostructured LiMn2O4 as a Fast Charging Cathode for Lithium Ion Batteries written by Benjamin Kalman Lesel and published by . This book was released on 2017 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pseudocapacitive materials provide a high energy density solution to fast charging, long cycle life energy storage. This work explores the pseudocapacitive characteristics and attempts to optimize nanostructured LiMn2O4 for use as a cathode material in fast charging, long cycle lifetime lithium ion batteries. Because slow kinetics in traditional batteries is linked to long lithium ion diffusion lengths through micron sized grains, the key to achieving pseudocapacitance in most materials is through nanostructuring to reduced diffusion distance. One of the most effective methods for producing nanostructures is through nanocrystal/polymer templating, which produces a porous structure with interconnected nanoscale walls capable of intercalating lithium ions at pseudocapactive rates. To make a full pseudocapacitive lithium ion battery a reality, however, a pseudocapacitive material of each electrode type, anode and cathode, must be paired. To date, many pseudocapacitive materials have been identified, but nearly all of them are redox active in a voltage range more suitable for anode materials. Recently, we identified a pseudocapacitive cathode material, nanostructured LiMn2O4 which shows impressive rate capabilities. Unfortunately, the improvements came at the cost of energy density, which decreased significantly with decreasing crystallite size. Kinetics for different crystallite sizes, however, increased suddenly below a certain critical crystallite size. We found that this critical crystallite size, below which pseudocapacitance occurred, was linked to a suppression of phase transition in nanoscale LiMn2O4. To address the capacity loss due to dissolution in high surface area nanostructured LiMn2O4 powders, a sol-gel templating method which formed dissolution resistant surfaces was employed. The resulting materials had long needle-like morphology and showed higher capacity and less dissolution than a similarly sized material synthesized with a different structure. It was concluded that the needles of the higher capacity structure were dissolution resistant surfaces along their lengths and therefore maintained higher energy density. In another approach, higher capacity was achieved in nanostructured LiMn2O4 with the addition of magnesium into the crystal structure. It was theorized that the increased capacity came from the magnesium ions stabilizing the surface from dissolution, therefore increasing capacity. This understanding and optimization of nanostructured LiMn2O4 has led to the first scalable pseudocapacitive cathode material that can be effectively used in fast charging, long cycle lifetime lithium ion batteries.

Book Synopsis Development of Nanostructured Alloy-based Composite Anode Materials for Lithium- and Sodium-ion Batteries by : Sang Ok Kim
Download or read book Development of Nanostructured Alloy-based Composite Anode Materials for Lithium- and Sodium-ion Batteries written by Sang Ok Kim and published by . This book was released on 2016 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium-ion batteries are the dominant energy storage technology in portable electronic applications due to their high energy density, long cycle life, and low self-discharge rate. Efforts to extend their implementation into rapidly growing electric vehicles and large-scale stationary energy storage devices require further improvements of performance and safety, as well as cost reduction. In this regard, the development of low-cost, advanced electrode materials for next generation lithium-ion batteries or sodium-ion batteries is increasingly being pursued to achieve these requirements. The purpose of this dissertation is to explore and develop several types of composite alloy-based anodes that can possibly lead to the enhancement of lithium- or sodium-storage performance. Alloy anodes have shown great potential for realization of high-performance lithium- or sodium-ion battery systems with enhanced safety as they offer high theoretical specific capacity and higher operating voltages than graphite. In addition, the successful employment of earth-abundant materials such as silicon and phosphorus could also result in a reduction in battery manufacturing cost. However, the major obstacles associated with the large volume change upon electrochemical reactions give rise to severe capacity fading in the first few cycles, making their implementation into commercial cells quite challenging. In order to overcome this issue, the alloy-based composite anodes are synthesized by applying the active/inactive matrix concept. The composites are capable of possessing the following advantages: (i) structural reinforcement and suppression of particle agglomeration upon cycling through a mechanically durable buffer; (ii) enhanced electrochemical reversibility and fast electrode kinetics through nanoscale active materials; (iii) high conductivity and facile electron transport through a conducting phase; (iv) high chemical and electrochemical stability through an electrochemically inert buffer. Moreover, the composites synthesized have reasonably high tap density that is beneficial for improving the volumetric capacity of lithium- or sodium-ion cells. In this dissertation, three different low-cost alloy-based composite anodes are developed by a low-cost, facile, and scalable high-energy mechanical milling: silicon-, zinc-, and phosphorus-based composites. All the composite systems studied in this work demonstrate enhancements in lithium- or sodium-ion storage performance in terms of high capacity, long cycle life, and high rate capability, while maintaining high tap density. By controlling the type and amount of an inactive matrix, the effects of each inactive matrix on the electrochemical performance of the composite anodes are investigated. In addition, the mechanism for the performance improvement is discussed.

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.

Book excerpt: 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.
