This book was released on 2023-10-12 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key R&D concern in the domain of new energy in recent years has been the large-scale development of electrochemical energy storage. However, the steep increase in pricing has constrained the further expansion of lithium-ion batteries, primarily due to the ongoing depletion of their scarce lithium supplies. A potential candidate material at the moment is the potassium-ion battery (KIB), which has an anode made of carbon and/or an alloy and rich reserves, offering an excellent theoretical capacity and ideal working voltage. More significant advancements are still required to achieve long life and high energy density, despite the fact that some significant breakthroughs have been reported. The most recent findings from research on carbon-based [graphite, hard carbon (HC), and nanoporous carbon] and alloy-based (mainly including Sb, Sn, P, and its compounds) anodes for KIBs are compiled in this document. Numerous simulations at the atomic level based on particular chemical interactions, phase transitions, ion/electron transport dynamics, and conduction band spin utilizing density functional theory (DFT) calculations have been conducted to thoroughly investigate the storage mechanism of K+ on various electrode materials. Moreover, this paper examined contemporary structural modification techniques used in carbon- and alloy-based anode electrode materials and applied DFT calculations to confirm the advancement of its thorough tests. To promote the manufacturing of rechargeable KIBs, the challenges and potential of KIBs were also explored in future research.

Book Synopsis Development of Flexible, Carbon-based Electrochemical Energy Storage Electrodes by : Ricky Tjandra
Download or read book Development of Flexible, Carbon-based Electrochemical Energy Storage Electrodes written by Ricky Tjandra and published by . This book was released on 2019 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into energy storage and conversion technologies has skyrocketed within the past few decades, motivated by the increased energy demands of our society and the threat of depleting energy sources. One of the exciting forefronts of energy storage research is the development of flexible electrochemical energy storage systems. This area of active research is fueled by the popularity of the Internet-of-Things (IOT), smart wearables/clothing and flexible electronics. A distinct lack of commercially available electrochemical energy storage options that can be flexed, bent, stretched and twisted is currently available to power these devices. Instead, most of today's flexible electronic and wearables rely on rigid cell formats such as cylindrical and prismatic cells. The problem of flexible energy storage devices can be broken down into 2 deficiencies: the lack of flexible electrodes that can match the performance of their rigid counterparts and the lack of high-performance solid-state electrolytes. Carbon-based materials, especially nanoscale materials such as graphene, are a potential solution to this problem due to their electronic conductivity, relative abundance, energy storage capabilities, and ability to be used in all parts of the energy storage system. All the work presented in this thesis involves the development and applications of carbon-based materials for flexible electrochemical energy storage systems. This thesis will explore two different pathways of achieving flexible electrodes based on carbon-based materials: - Replacement of non-flexible metal foil current collectors using flexible carbon-based current collectors - Elimination of current collectors and binders by using carbon-based, free-standing materials Firstly, this thesis will explore the use of carbon cloth as a substrate for a novel TiO2 nanocrystal material for use as an anode in flexible lithium-ion supercapacitors. Although lithium-ion supercapacitors are the focus of this study, the same composite material can also be used as an anode in traditional lithium-ion batteries. The resulting carbon cloth/TiO2 composite is able to withstand 100 flexion cycles while still retaining its energy storage capabilities, showing the advantage of the carbon cloth as a substrate when compared to traditional metal foils. The composite is also successfully integrated into a flexible pouch cell that delivers an excellent reversible capacity of 270 mAh g-1. This work establishes that carbon cloth can be used to replace metal foils as a flexible current collector without sacrificing electrochemical performance. Secondly, this thesis explores the use of a nitrogen-rich carbon foam based on the carbonization of melamine formaldehyde and graphene oxide for use in lithium-ion hybrid capacitors. The foam presented here can be used as-is as a flexible, free-standing, binder-free anode for lithium-ion hybrid capacitors/batteries. Furthermore, the foam can also be used as a 3-dimensional current collector for other active materials both in the anode and the cathode, which demonstrates its versatility for electrochemical energy storage systems. An all-carbon based lithium-ion hybrid supercapacitor has been fabricated using the foam as both an active material for the anode and the current collector for the activated carbon cathode. The cell shown in this chapter achieved an energy density of 40 Wh kg-1 which is superior to that reported in the literature that are based purely on carbon materials. The work presents a novel carbon-based flexible electrode material and concept device that also enables the removal of binders and current collectors from traditional batteries and supercapacitors, bringing us one step closer to achieving a fully flexible electrochemical energy storage system. Finally, graphene quantum dots (GQDs) have been synthesized using a simple peroxide-assisted method. The GQDs are then electrodeposited onto carbon cloth to make an all-carbon, binder-free, flexible electrode for supercapacitors. This work builds off the TiO2/carbon cloth composite by replacing the TiO2 with a carbon-based nanomaterial. Presently reported research has involved the use of GQDs either in conjunction with another active material or used as an active material on rigid, planar substrates. We have shown that GQDs can function as a stand-alone active material for EDLC capacitors. At the time of writing, this work shows the first such use of GQDs on a non-planar, flexible substrate for supercapacitors. All the work in this thesis centers around the use of carbon-based materials and their composites towards the development of flexible electrodes for lithium-ion batteries, supercapacitors and their hybrids. This thesis provides insights into the viability of using various carbon-based materials in different aspects of flexible electrodes and provides a basis for future investigations into this topic.
Download or read book Honey-Bee written by Anatole France and published by Library of Alexandria. This book was released on 2020-09-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea covers to-day what was once the Duchy of Clarides. No trace of the town or the castle remains. But when it is calm there can be seen, it is said, within the circumference of a mile, huge trunks of trees standing on the bottom of the sea. A spot on the banks, which now serves as a station for the customhouse officers, is still called "The Tailor's Booth," and it is quite probable that this name is in memory of a certain Master Jean who is mentioned in this story. The sea, which encroaches year by year, will soon cover this spot so curiously named. Such changes are in the nature of things. The mountains sink in the course of ages, and the depths of the seas, on the contrary, rise until their shells and corals are carried to the regions of clouds and ice. Nothing endures. The face of land and sea is for ever changing. Tradition alone preserves the memory of men and places across the ages and renders real to us what has long ceased to exist. In telling you of Clarides I wish to take you back to times that have long since vanished. Thus I begin: The Countess of Blanchelande having placed on her golden hair a little black hood embroidered with pearls.... But before proceeding I must beg very serious persons not to read this. It is not written for them. It is not written for grave people who despise trifles and who always require to be instructed. I only venture to offer this to those who like to be entertained, and whose minds are both young and gay. Only those who are amused by innocent pleasures will read this to the end. Of these I beg, should they have little children, that they will tell them about my Honey-Bee. I wish this story to please both boys and girls and yet I hardly dare to hope it will. It is too frivolous for them and, really, only suitable for old-fashioned children. I have a pretty little neighbour of nine whose library I examined the other day. I found many books on the microscope and the zoophytes, as well as several scientific story-books. One of these I opened at the following lines: "The cuttle-fish Sepia Officinalis is a cephalopodic mollusc whose body includes a spongy organ containing a chylaqueous fluid saturated with carbonate of lime." My pretty little neighbour finds this story very interesting. I beg of her, unless she wishes me to die of mortification, never to read the story of Honey-Bee.
Download or read book Na-ion Batteries written by and published by John Wiley & Sons. This book was released on 2021-05-11 with total page 386 pages. Available in PDF, EPUB and Kindle. 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.
