Materials Development for Active/Passive Components of a Supercapacitor


Book Description

This brief deals with various forms of supercapacitors starting from traditional carbon based supercapacitors to advanced next generation hybrid supercapacitors. The primary focus is to investigate the successive evolution in the core components of a typical supercapacitor which will bring significant observations regarding their feasibility and overall impact on the charge storage capacity so as to reach at par with the current battery technology. The authors present a critical review of the current collectors, electrode materials and electrolytic components which have distinctive impact on both the power and energy density of a supercapacitor. Emerging trends in the fabrication of hybrid supercapacitor technology bring together the exceptional power density of a double layer capacitor and energy density of a rechargeable battery, which promises a brighter future for the electrical energy storage system.

Supercapacitors


Book Description

Supercapacitors are a relatively new energy storage system that provides higher energy density than dielectric capacitors and higher power density than batteries. They are particularly suited to applications that require energy pulses during short periods of time, e.g., seconds or tens of seconds. They are recommended for automobiles, tramways, buses, cranes, fork-lifts, wind turbines, electricity load leveling in stationary and transportation systems, etc. Despite the technological maturity of supercapacitors, there is a lack of comprehensive literature on the topic. Many high performance materials have been developed and new scientific concepts have been introduced. Taking into account the commercial interest in these systems and the new scientific and technological developments now is the ideal time to publish this book, capturing all this new knowledge. The book starts by giving an introduction to the general principles of electrochemistry, the properties of electrochemical capacitors, and electrochemical characterization techniques. Electrical double layer capacitors and pseudocapacitors are then discussed, followed by the various electrolyte systems. Modelling, manufacture of industrial capacitors, constraints, testing, and reliability as well as applications are also covered. 'Supercapacitors - Materials, Systems, and Applications' is part of the series on Materials for Sustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.




Honey-Bee


Book Description

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.
